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:
- 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
- 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.

- 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.
