Week 5
At the beginning of our wetlab phase, we wanted to transform E. coli cells with plasmids containing an indigoidine synthetase and a 4'-Phosphopanthetheinyl-transferase (PPTase) to see whether we can observe blue colonies on our plates as this has been reported by groups working with indigoidine synthetases (<bib id="Takahashi2007"/><bib id="Brachmann2012"/>).
We focused on the work of Marius Müller et. al. in 2012 (<bib id="Muller2012"/>). The group used the bpsA indigoidine synthetase (blue pigment synthetase A) from S. lavendulae ATCC11924 (<bib id="Takahashi2007"/>) and the PPTase svp from S. verticillus ATCC15003 (<bib id="Sanchez2001"/>) to establish both a fluorescence and a chromophore based reporter assay for mammalian cells by expression of bpsA and svp which results in production of a blue pigment/ fluorophore. The group kindly supported us by sending two of their constructs, namely the pET derived expression vectors pMM64 carrying the bpsA indigoidine synthetase with an ampicillin resistance gene and pMM65 carrying svp and a kanamycin resistance gene. Both bpsA and svp rom the Fussenegger lab are codon-optimized versions for expression in eukaryotic cell lines.
We transformed competent E. coli TOP10 with each plasmid to prepare plasmid DNA and perform a cotransformation of an E. coli Rosetta strain with both plasmids. Transformed cells which carry both plasmids should produce the blue pigment indigoidine.
Unfortunately, there were no blue colonies after the co-transformation. We repeated the experiment under various growth conditions; i.e. we used different incubation temperatures, light conditions, shaking and addition of ascorbic acid, which was reported to stabilize indigoidine in liquid cultures (<bib id="Muller2012"/>).

Week 9
In order to transfer the gold precipitating NRPS from D. acidovorans to E.coli, the necessary modules will be amplified from the D. acidovorans genome and assembled as plasmids. Due to its large size of 18 Kb, the module DelH will be expressed on a separate plasmid. A strategy was developed, primers designed accordingly and necessary BioBricks obtained from the distribution. The D. acidovorans was obtained from the DSMZ and cultured in Acidovorax complex medium.
Week 10
In order to clone the Delftibactin cluster from D. Acidovorans we decided to use Gibson cloning. Accordingly Gibson Primers were designed to amplify our target backbone pSB4K5 with an overlap to DelA. Furthermore the Gibson Primer designed to join DelOP with DelAF will introduce the ribosome binding site BBa_BNILS. Accordingly the Gibson Primer designed to join DelL with DelOP will introduce the ribosome binding site BBa_BAGAINNILSYOUNOOB.

At the beginning of the week, we could verify that the Gibson Assembly for Tripeptide I was indeed positive, however, the other Gibson Assemblies did not work properly. Instead of picking new colonies, we decided to optimize the Gibson recipe instead, as backbone religations were the most common problem. With these improved protocols, we used Gibson Assembly for the Dipeptide, Tripeptide II and Tetrapeptide I, later that week, Tetrapeptide II followed. After the Transformation to DH10β cells and screening by restriction digest we could send samples for the Dipeptide and Tetrapeptide I to sequencing and obtained a positive alignment. Hence we transformed BAP I cells with the positive constructs. The same was...

Results:
- concentrations are not sufficient for gibson assembly
- PCR will be repeated and gel slices of different reactions will be pooled for one gel extraction using QIAquick Gel Extraction Kit to obtain the concentrations needed for gibson assembly
Restriction digest of fragment FS_02 to FS_05; 11.2 kb; 11-08-2013 with EcoRI-HF
Incubation at 37°C for 2 hours 45min
| what | µL |
|---|---|
| FS_02 to FS_05 (11-08-2013) | 18 |
| EcoRI-HF | 1 |
| CutSmart Buffer | 2.5 |
| dd H2O | 3.5 |
Expected fragment sizes: 2.26kbp; 4.62kbp; 4.32kbp
Results:
- One band of about 5kbp and one of 2.5kbp
- no clear result, digest will be repeated with another enzyme (ClaI), as the enzyme used was beyond expiration date
Restriction digest of fragment FS_02 to FS_05; 11.2 kb; 10-08-2013 with ClaI
Incubation at 37°C for 2 hours
| what | µL |
|---|---|
| FS_02 to FS_05 (10-08-2013) | 20 |
| ClaI | 1 |
| CutSmart Buffer | 2.5 |
| dd H2O | 1.5 |
Expected fragment sizes: 6.9kbp, 4.3kbp
Results:
- restriction digest displays the expected fragments, therefore amplification of the desired fragment can be assumed
- PCR product will be prepared for sequencing by GATC to proof amplification of the desired DNA sequence before Gibson Assembly
