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 DMSZ-German Collection of Microorganism and Cell Cultures (DMSZ no.14576). For more informations you will see our [https://2012.igem.org/Team:TU_Darmstadt/Project/Metabolism project discription].

Labjournal Metabolism

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]). For more informations you will see our project discription.

  • Functional testing of BBa_J23100-xylE-dT
    • We inoculated 2 x 50 mL LB-media-ampicilin with 10 µl of the glycerine stock BBa_J23100-xylE-dT
    • After incubation we centrifuged the culture at 4600x g for 10 minutes
    • We resuspended each pellet in 3 mL PBS buffer and added PBS to 120 ml
    • We added 2 mL of 0.5 M catechol solution to the first cell suspension
    • We added 2 ml of 0.5 M protocatechuic acid to the second cell suspenion
    • We observed in either colony a colour change from colourless to light yellow.
      • Conclusion: XylE accepted protocatechuic acid as a substrate.
  • Kinetic assay of XylE with protocatechuic acid as a substrate
    • We inoculated 50 mL LB-media-ampicilin with 10 µl of the glycerine stock BBa_J23100-xylE-dT

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

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

Enzyme assays

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

    • After the addition of XylE we observed a very high activity.
