This lab journal describes a isolation and characterisation of the terephthalic acid 1,2-dioxigenase system and an dihydrodiol decarboxylase from Comamonas testosteroni KF-1 in Escherichia Coli. The strain was purchased from DSMZ-German Collection of Microorganism and Cell Cultures (DSMZ no.[http://www.dsmz.de/catalogues/details/culture/DSM-14576.html?tx_dsmzresources_pi5%5BreturnPid%5D=304 14576]).

Purification of TphA2

Protein purification according to standard strep-tag purification protocol

Note: We didn't perform an SDS-Page from the purification.

week 19 (17.-21.09.12)

Gel permeation chromatography

We performed the GPC with the following conditions:

Instrument	Pharmacia FPLC System
Colum	Superose 6 10/30
Mobile phase	PBS pH 7.4
Detector	280 nm
Flow rate	0.5 ml/min
Progam	Isocatic

We injected 50 µl of fraction 3 from each protein (TphA1, TphA2, TphA3, TphB and AroY) for analysis of the molar mass and the oligomerization.
- Results:

GPC analysis of TphA3. The Peak of TphA3 has a retention time of 33 minutes. This retention time corresponds to a molar mass of 52 kDa, approximately.

GPC analysis of TphB. The Peak of TphB has a retention time of 32.5 minutes. This retention time corresponds to a molar mass of 64 kDa, approximately. The peak at minute 13 is an undefined contamination.

GPC analysis of AroY. The Peak of AroY has a retention time of 28 minutes. This retention time corresponds to a molar mass of 285.4 kDa, approximately.

Note: The GPC analysis of TphA2 and TphA1 respectively didn't work. The peak at 39 minutes is desthiobiotin from the protein purification.

Operon Construction

After several failed cloning attempts a test restriction digest was performed

Test restriction of J61002-RBS-tphA1-RBS-tphA2-RBS-tphA3-RBS-tphB, J61002-aroY and BBa_K316003 (far left: Lambda DNA/Eco47I (AvaII) Marker, 13)

J61002-RBS-tphA1-RBS-tphA2-RBS-tphA3-RBS-tphB showed unexpected bands although only one was expected after cutting with SpeI and PstI
BBa_K316003 showed two bands when cut with PstI and SpeI and PstI respectively where only one was expected
This lead us to the assumption that our PstI enzyme was contaminated with EcoRI (note the slightly differences between BBa_K316003 cut with SpeI and PstI and BBa_K316003 cut with XbaI and PstI)
Nevertheless also J61002-RBS-tphA1-RBS-tphA2-RBS-tphA3-RBS-tphB seemed to possess mutation(s) introducing new recognition sites for SpeI and/or PstI
As we lacked time to confirm our assumptions by sequencing we decided to cancel further operon construction

week 20 (24.-26.09.12)

Enzyme assays

Tph enzymes
- For the protocol, see here
- We didn't measure the activity.

AroY
- For the protocol, see here
- Before the addition of XylE we observed a brown solution. The brown color is typical for 1,2-Benzoquinone.
- After the addition of XylE we observed a very high activity.

Functional test for AroY:
1) AroY with 50 mM Protocatechuate after 24 h;
2) after addition of [http://partsregistry.org/Part:BBa_K316003 XylE] and 10 min incubation

+*BBa_K316003 showed two bands when cut with PstI and SpeI and PstI respectively where only one was expected
+*This lead us to the assumption that our PstI enzyme was contaminated with EcoRI (note the slightly differences between BBa_K316003 cut with SpeI and PstI and BBa_K316003 cut with XbaI and PstI)
+*Nevertheless also J61002-RBS-tphA1-RBS-tphA2-RBS-tphA3-RBS-tphB seemed to possess mutation(s) introducing new recognition sites for SpeI and/or PstI
+*As we lacked time to confirm our assumptions by sequencing we decided to cancel further operon construction
