This page features the work carried out by the [https://2012.igem.org/Team:TU_Darmstadt/Project/Degradation degradation team]. The main objectives were the production of a BioBrick containing ''[https://2012.igem.org/Team:TU_Darmstadt/Materials/FsC Fusarium solani cutinase]'' or ''[https://2012.igem.org/Team:TU_Darmstadt/Materials/Est13 Est13 esterase]'' two enzymes potentially enabling ''E.coli'' of [https://2012.igem.org/Team:TU_Darmstadt/Materials/PET PET] degradation and over-expression stems for activity screening.
This page features the work carried out by the [https://2012.igem.org/Team:TU_Darmstadt/Project/Degradation degradation team]. The main objectives were the production of a BioBrick containing ''[https://2012.igem.org/Team:TU_Darmstadt/Materials/FsC Fusarium solani cutinase]'' or ''[https://2012.igem.org/Team:TU_Darmstadt/Materials/Est13 Est13 esterase]'' two enzymes potentially enabling ''E.coli'' of [https://2012.igem.org/Team:TU_Darmstadt/Materials/PET PET] degradation and over-expression stems for activity screening.
 +
 +
The [https://2012.igem.org/Team:TU_Darmstadt/Team#Degradation degradation group] consists of six undergraduates and two PhD student advisors. Our objective is the expression of a fusion protein on the surface of ''E. coli'' to enable a microbial polyethylenterephtalate (PET) degradation.
 +
 +
We identified three potential PET degradation enzymes from literature. Two of them are cutinases HiC (''Humicola insolens'' cutinase) and FsC (''Fusarium solani'' cutinase), the other namely pNB-Est13 beeing an esterase. After a short examination we dropped the HiC due to a temperature optimum of 80+°C. Shortly after the FsC was dropped as well, due to its toxicity for ''E.coli''.[[File:Project_overview_degradation.png|450px|thumb|right|Enzymatical degradation of polyethylen terephtalate (PET) to terephtalic acid (TPA)]]
 +
In order to maximise the activity we decided to anchor and display the cutinase/esterase directly on the surface of the producing bacterial cell. Surface-exposed enzymes are directly accessible to the respective substrates which no longer have to traverse the cellular membrane barriers. Furthermore, the enzyme reaction occurs in a chemically more defined environment as compared to the interior of a microbial cell. We use the outer membrane proteins of ''Pseudomonas aeruginosa'' (EstA) as a membrane anchor and the signaling sequence of PhoA translocators to display the enzyme on the outer surface of ''E. coli'' cells. In addition the fusion protein contains a his-tag and a myc-tag for  detection via flow cytometry after antibody staining or Western blot.The [https://2012.igem.org/Team:TU_Darmstadt/Team#Degradation degradation group] consists of six undergraduates and two PhD student advisors. Our objective is the expression of a fusion protein on the surface of ''E. coli'' to enable a microbial polyethylenterephtalate (PET) degradation.
 +
 +
At first the signal sequence (PhoA), the catalytic domain (FsC/Est13) and EstA were assembled inline from their respective vectors. This is due to the fact, that by combining multiple parts in the standardized BioBrick vectors, scars with stop codons are generated that would effectively prevent the fusionproteins expression. In consideration of the DNA constructs length we pursued two PCR based synthesis strategies. One being the SKV (standard cloning procedure) the other being the SOE (standard overlap procedure). The first using primers and restriction sites for assembly the latter using overlapping primers. During both assembly procedures restriction sites of PstI, EcorI, SpeI or XbaI were eliminated from the coding sequence by mutagene PCR. In the end we completely changed our assembly strategy, using synthesis products and BsaI sites to put our parts together. After completion the fusionprotein and its subunits were transfered to the BioBrick standard and sent to the registry.
 +
For further characterisation the enzymes were overexpressed in E. coli strains Top10, DH5α, Mg1655, screened on tributyrin agar and detected via flow cytometry after performing an antibody staining. The material science group went even further and tried to examine them using AFM.

[[File:Splicing_by_Overlapp_extension.svg.png|300px|left|thumb|schematic drawing of SOE PCR. the red gene has to be assembled upstream of the blue gene. Pay attention to the primer overlapps.]]
 +
 +
 +
 +
SOE PCR stands for ''Splicing by Overlapp Extension PCR''. It is a standard overlapp extension procedure, enabling the assembly of genes wihtout performing any cloning, digesting or ligation inbetween.
 +
All you need to do ist running PCRs with specific primers. If gene A is the upstream part and gene B has to be assembled downstream of gene A, primer lo of gene A should have an overlapp of around 20 nucleotides complementary to the first 20 nucleotides of gene B. Primer up of gene B should haven a complementary overlapp of 20 nucleotides to the end of gene A.
 +
 +
We stopped using SOE PCR after a couple of weeks. It is a good method to perform mutationial PCR but to assemble genes of the length of [http://partsregistry.org/wiki/index.php?title=Part:BBa_K808032 BBa_K808032] it is not the best. Due to bad yields of gel extraction after the first assembly steps we stopped SOE PCR and went on with [https://2012.igem.org/wiki/index.php?title=Team:TU_Darmstadt/Labjournal/Degradation#SKV SKV]. But eventually we got our chimeric genes synthesized by [http://de-de.invitrogen.com/site/de/de/home/Products-and-Services/Applications/Cloning/gene-synthesis/GeneArt-Gene-Synthesis.html GeneArt].

The shortcut SKV stands for "Standard Klonierungs Verfahren", in english standard molecular cloning. The team tried to build up the whole construct without usage of the BioBrick system as a second way. Here the team had to generate many primers with different restriction sites to connect the parts of the construct.

We use our induced cells (Top10) with an OD<sub>600</sub>=0.1-0.025 (resuspended in PBS-buffer) as catalysts and ''para-Nitrophenylbutyrate'' as a substrate. Induced cells have the [http://partsregistry.org/Part:BBa_K808030 fusion protein (BBa_K808030)] expressed on their surface. The catalytical domain, formed by pNB-Esterase 13 will show hydrolytic activity we can screen for by performing a [https://2012.igem.org/Team:TU_Darmstadt/Protocols/pNP_Assay pNP-assay]. The substrate will be hydrolysed, and one degradation construct is ''para-Nitrophenylbutyrate''. If released by hydrolysis, a characeristic absorption at 405 nm can be detected and plotted against the time, resulting in straight lines.  The hydrolytic activity is quantified by the slope of the respective straight line.

 +
===== Procedure =====
 +
 +
Round about 1g of PET granulate is added in each two falcon tubes to between 15 and 20 mL water of pH = 7.4 and several drops of [http://en.wikipedia.org/wiki/Bromothymol_blue bromothymol blue]. In one of these falcon tubes Est13 stock solution is added until a concentration of 2,5 µM is reached. For 15 days the solutions are incubated at room temperature. At nine specific days of these the enzymatic solutions and the negative sample are photographed, to control the shift of pH.
 +
 +
===== Results =====
 +
In all photos the degradation with Est13 is in the left falcon tube.

 +
 +
 +
 +
The photos show a decrease of the pH-value over time in the sample containing Est13. The one without this enzyme remains unchanged. So it is concluded that Est13 degrades PET granulate.

 +
[[File:principle of degradation of monomethyl terephthalate.png]]<br />
 +
Conditions: Room temperature (~22°C)
 +
 +
===== Procedure =====
 +
 +
Three different samples of 30 mL dest. water at a pH of 7.4 are incubated for 7 days with a concentration 500µM of monomethyl terephthalate (solved in methanol) and following ingredients:
 +
 +
1. 30µL of FsC (concentration in the incubated solution: ~0,8µM)<br />
 +
2. 30µL of Est13 (concentration in the incubated solution: ~0,8µM)<br />
 +
3. Nothing<br />
 +
 +
To control the shift of the pH during the estercleavage some drops of [http://en.wikipedia.org/wiki/Bromothymol_blue bromothymol blue] are added.
 +
 +
===== Results =====
 +
 +
Following pictures show the shift of the pH over 7 days (The degaradation with Est13 is in the left falcon tube and with FSC in the middle one):
 +
 +
[[File:monomethyl terephthalate degradation at day 1.jpg|thumb|445px|left|Day1: Degradation of monomethyl terephthalate. Left: with Est13(~0,8µM) Middle: with FSC(~8µM) Right: Negativ sample]]

 +
 +
So you can see that both enzymes catalyzed the cleavage of the ester in a few days. In 7 days the pH-value shifted about one unit.

===== Procedure =====
 +
 +
The procedure is the same like in the [https://2012.igem.org/Team:TU_Darmstadt/Protocols/pNP_Assay#Enzyme pNP-assay].

 +
 +
===== Interpretation =====
 +
 +
The result shows that Est13 can catalyze the cleavage of both esters. FsC cannot do this in the given conditions. It is not clear what the reasons for the deactivation of FsC are. Maybe DMSO and/or methanol inhibit the enzyme or it is even not able to catalyze the hydrolysis.

Degradation

This page features the work carried out by the degradation team. The main objectives were the production of a BioBrick containing Fusarium solani cutinase or Est13 esterase two enzymes potentially enabling E.coli of PET degradation and over-expression stems for activity screening.

The degradation group consists of six undergraduates and two PhD student advisors. Our objective is the expression of a fusion protein on the surface of E. coli to enable a microbial polyethylenterephtalate (PET) degradation.

We identified three potential PET degradation enzymes from literature. Two of them are cutinases HiC (Humicola insolens cutinase) and FsC (Fusarium solani cutinase), the other namely pNB-Est13 beeing an esterase. After a short examination we dropped the HiC due to a temperature optimum of 80+°C. Shortly after the FsC was dropped as well, due to its toxicity for E.coli.
Enzymatical degradation of polyethylen terephtalate (PET) to terephtalic acid (TPA)

In order to maximise the activity we decided to anchor and display the cutinase/esterase directly on the surface of the producing bacterial cell. Surface-exposed enzymes are directly accessible to the respective substrates which no longer have to traverse the cellular membrane barriers. Furthermore, the enzyme reaction occurs in a chemically more defined environment as compared to the interior of a microbial cell. We use the outer membrane proteins of Pseudomonas aeruginosa (EstA) as a membrane anchor and the signaling sequence of PhoA translocators to display the enzyme on the outer surface of E. coli cells. In addition the fusion protein contains a his-tag and a myc-tag for detection via flow cytometry after antibody staining or Western blot.The degradation group consists of six undergraduates and two PhD student advisors. Our objective is the expression of a fusion protein on the surface of E. coli to enable a microbial polyethylenterephtalate (PET) degradation.

At first the signal sequence (PhoA), the catalytic domain (FsC/Est13) and EstA were assembled inline from their respective vectors. This is due to the fact, that by combining multiple parts in the standardized BioBrick vectors, scars with stop codons are generated that would effectively prevent the fusionproteins expression. In consideration of the DNA constructs length we pursued two PCR based synthesis strategies. One being the SKV (standard cloning procedure) the other being the SOE (standard overlap procedure). The first using primers and restriction sites for assembly the latter using overlapping primers. During both assembly procedures restriction sites of PstI, EcorI, SpeI or XbaI were eliminated from the coding sequence by mutagene PCR. In the end we completely changed our assembly strategy, using synthesis products and BsaI sites to put our parts together. After completion the fusionprotein and its subunits were transfered to the BioBrick standard and sent to the registry. For further characterisation the enzymes were overexpressed in E. coli strains Top10, DH5α, Mg1655, screened on tributyrin agar and detected via flow cytometry after performing an antibody staining. The material science group went even further and tried to examine them using AFM.

SOE PCR

schematic drawing of SOE PCR. the red gene has to be assembled upstream of the blue gene. Pay attention to the primer overlapps.


SOE PCR stands for Splicing by Overlapp Extension PCR. It is a standard overlapp extension procedure, enabling the assembly of genes wihtout performing any cloning, digesting or ligation inbetween. All you need to do ist running PCRs with specific primers. If gene A is the upstream part and gene B has to be assembled downstream of gene A, primer lo of gene A should have an overlapp of around 20 nucleotides complementary to the first 20 nucleotides of gene B. Primer up of gene B should haven a complementary overlapp of 20 nucleotides to the end of gene A.

We stopped using SOE PCR after a couple of weeks. It is a good method to perform mutationial PCR but to assemble genes of the length of [http://partsregistry.org/wiki/index.php?title=Part:BBa_K808032 BBa_K808032] it is not the best. Due to bad yields of gel extraction after the first assembly steps we stopped SOE PCR and went on with SKV. But eventually we got our chimeric genes synthesized by [http://de-de.invitrogen.com/site/de/de/home/Products-and-Services/Applications/Cloning/gene-synthesis/GeneArt-Gene-Synthesis.html GeneArt].

Molecular cloning.jpg

The shortcut SKV stands for "Standard Klonierungs Verfahren", in english standard molecular cloning. The team tried to build up the whole construct without usage of the BioBrick system as a second way. Here the team had to generate many primers with different restriction sites to connect the parts of the construct.

Sequencing was not successfull. It was discovered later, that there was a contamination of the DH5alpha cells with other plasmid-DNA, probably caused by Electroporation. SOE-PCR
Due to this fact, the isolated plasmids were always mixed up with other plasmids, and sequencing had to fail. The contamination of the cells may have also caused false-positive results of the colony-PCRs.

We suggest that the cutinase FSC has an additional lipase-activity, which causes a lysis of the cell-membrane and may have an selective effect on FSC-negative mutants while cultivating the cells.

Trouble shooting

  • Symptoms
    • very much transformants on crossed out plates after bacterial transformation by Electroporation
    • at first Colony PCR is positive
    • Minipreps result in very high yields (exceeding >200 ng/µL)
    • second Colony PCR is negative
    • sequencing failed
    • BUT FsC in [http://partsregistry.org/Part:pSB1C3 pSB1C3]
      • has had not very much transformants
      • has had a seuqencing result
      • its Minipreps resulted in medium concentrations, settling around 90 ng/µL
  • Diagnosis:
    • our bacterial transformation is done by Electroporation
    • therefor we use electroporation cuvettes, stored in DNA precipitating liquids like isopropanol or ethanol after being washed out.
    • long before we started these electroporation cuvettes were in use.
    • if not washed out carefully, DNA debris (like vectors and Inserts) accumulates in these storage liquids, due to precipitation
    • when an Electroporation is performed with one of these cuvettes, probably containing only little DNA debris, the cells get transformed with numbers of different precipitated plasmids
    • these plasmids contain a variety of resistances, reaching from CAM over KAN to Amp, allowing even "wrong" transformants to grow on selective media
    • after a short period of time, bacterial colonies start to seperate and repel their plasmids, selecting only the most "comfortables"
    • probably our plasmids, containing big genes on ligated vectors, are pushed out during this phase of selection
    • this slow decrease of plasmid could explain the missing second positive signal of Colony PCR

The catalytical domain, formed by pNB-Esterase 13 will show hydrolytic activity we can screen for by performing a pNP-assay. The substrate will be hydrolysed, and one degradation construct is para-Nitrophenylbutyrate. If released by hydrolysis, a characeristic absorption at 405 nm can be detected and plotted against the time, resulting in straight lines. The hydrolytic activity is quantified by the slope of the respective straight line.

Km and Vmax calculation

To find Km the growth of the first seven data points were written down in a diagram. The slope of the regression line gave the speed of the hydrolysis for the single substrate concentrations. Now the value of the speed with the associated concentration of substrate were plotted in a Lineweaver-Burk diagram. At the point where the regression line is crossing the x-axis the x-coordinate amounts to -1/Km. So Km is about 400µM. To calculate the value of Vmax we used the point where the plotted line crosses the y-axis. The associated y-coordinate is 1/Vmax. Consequently Vmax for 50nM Est13 is 0,002798 1/s.

Kcat calculation

The value Kcat is calculated through dividing Vmax by the enzyme concentration of 50nM. Kcat counts 0,055951 1/mol*s.

FsC with ehtylenglycol

Our Simulation lab was able to show , theoratically, a relation between an decrease of enzyme activity and an increase of ethylenglycol concentration. This could be a hint for the mysterious loss of hydrolysis when the degradation rate reaches 5% of PET foil weight as it is described in the literature (Ronkvist, Å. M., Xie, W., Lu, W., & Gross, R. a. (2009). Cutinase-Catalyzed Hydrolysis of Poly(ethylene terephthalate). Macromolecules, 42(14), 5128–5138. doi:10.1021/ma9005318). We tried to proof their theory of potentially higher ethylenglycol concentration surrounding the PET foil. An increasing amount of ehtylenglycol should hamper the hydrolytic activity of FsC in a pNP-assay.

Procedure

The lab test procedure was nearly equal to the normal kinetics records with only one difference. The reaction solution consisted of different composites of PBS buffer and ethylenglycol (0 - 20%). All records were done at a concentration of 1mM of 4-Nitrophenyl butyrate in the experiment.

Records of the different ethylenglycol concentrations and the associated speeds of hydrolisis in a diagram
Plot of enzyme activity related to an increasing ehtylenglcol concentration
Interpretation

As you can see there is a stagnation of the speed of hydrolysis of the ester caused by an increasing concentration of ethylenglycol. But by that you cannot tell that ethylenglycol inhibits the FsC, because the hydrolysis of the ester rose with a higher concentration of ethylenglycol in the negative samples. So it could be that the ethylenglycol starts a concurrent reaction or blocks the 4-Nitrophenyl butyrate.

PET degradation

Principle and conditions
principle of hyrolytic PET degradation. Conditions: Room temperature (~ 22°C) pH = 7.4

Procedure

Round about 1g of PET granulate is added in each two falcon tubes to between 15 and 20 mL water of pH = 7.4 and several drops of [http://en.wikipedia.org/wiki/Bromothymol_blue bromothymol blue]. In one of these falcon tubes Est13 stock solution is added until a concentration of 2,5 µM is reached. For 15 days the solutions are incubated at room temperature. At nine specific days of these the enzymatic solutions and the negative sample are photographed, to control the shift of pH.

Results

In all photos the degradation with Est13 is in the left falcon tube.

Day1:Degradation of PET. Left: With Est13(2,5µM) Right: Negative control
Day2:Degradation of PET. Left: With Est13(2,5µM) Right: Negative control
Day3:Degradation of PET. Left: With Est13(2,5µM) Right: Negative control
Day7:Degradation of PET. Left: With Est13(2,5µM) Right: Negative control
Day9:Degradation of PET. Left: With Est13(2,5µM) Right: Negative control
Day10:Degradation of PET. Left: With Est13(2,5µM) Right: Negative control
Day13:Degradation of PET. Left: With Est13(2,5µM) Right: Negative control
Day15:Degradation of PET. Left: With Est13(2,5µM) Right: Negative control



The photos show a decrease of the pH-value over time in the sample containing Est13. The one without this enzyme remains unchanged. So it is concluded that Est13 degrades PET granulate.

Degradation of monomethyl terephthalate over time

Principle and conditions

Principle of degradation of monomethyl terephthalate.png
Conditions: Room temperature (~22°C)

Procedure

Three different samples of 30 mL dest. water at a pH of 7.4 are incubated for 7 days with a concentration 500µM of monomethyl terephthalate (solved in methanol) and following ingredients:

1. 30µL of FsC (concentration in the incubated solution: ~0,8µM)
2. 30µL of Est13 (concentration in the incubated solution: ~0,8µM)
3. Nothing

To control the shift of the pH during the estercleavage some drops of [http://en.wikipedia.org/wiki/Bromothymol_blue bromothymol blue] are added.

Results

Following pictures show the shift of the pH over 7 days (The degaradation with Est13 is in the left falcon tube and with FSC in the middle one):

Day1: Degradation of monomethyl terephthalate. Left: with Est13(~0,8µM) Middle: with FSC(~8µM) Right: Negativ sample
Day8: Degradation of monomethyl terephthalate. Left: with Est13(~0,8µM) Middle: with FSC(~8µM) Right: Negativ sample

So you can see that both enzymes catalyzed the cleavage of the ester in a few days. In 7 days the pH-value shifted about one unit.

Principles, conditions and method
Principle of degradation of 4-nitrophenyl-3-phenylpropanoate
Principle of degradation of bis(4-nitrophenyl) succinat

Conditions and method are listed by the pNP-assay.

Procedure

The procedure is the same like in the pNP-assay. Only if bis(4-nitrophenyl) succinate is added, add 900µL of reagent A to 100µL of reagent B in step 1.

Results
Plot of enzyme activities on 4-nitrophenyl-3-phenylpropanoate and bis(4-nitrophenyl) succinate
Interpretation

The result shows that Est13 can catalyze the cleavage of both esters. FsC cannot do this in the given conditions. It is not clear what the reasons for the deactivation of FsC are. Maybe DMSO and/or methanol inhibit the enzyme or it is even not able to catalyze the hydrolysis.
