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.</p>

In order to transfer the gold precipitating NRPS from <i>D. acidovorans</i> to <i>E.coli</i>, 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 <i>D. acidovorans</i> was obtained from the DSMZ and cultured in Acidovorax complex medium.

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.

Results:

  • A weak band was visible, but it was on the wrong height.
  • Accidently the band was cut anyway.
  • Either the primers did not bind or the DNA still had to many secondary structures --> the consequence is to change the annealing temperature.

Results:

  • Amplification of DelOP was successfull
  • The gradient PCR shows that amplification worked best with an annealing temperature of 72.3°C, interestingly this annealing temperature was used for the remaining mastermix of the gradient PCR which included more DMSO than the other samples as mixing of DMSO often is not perfect and therefore the very last sample is of higher DMSO concentration
  • Therefore PCR will be repeated with an annealing temperature of 72.3°C and 10% DMSO
