Week 10
This week the project DelRest was launched. In order to clone the Delftibactin cluster from D. Acidovorans into E.coli we decided to use Gibson cloning. Therefore Gibson primers were designed to amplify our target backbone pSB4K5 with an overlap to DelA. Furthermore the Gibson primer connecting DelOP and DelAG introduces the ribosome binding site BBa_BNILS. Accordingly the Gibson primer for joining DelL with DelOP includes the ribosome binding site BBa_BNILS. The very last gibson primer used to amplify DelL consequently has an overlap to the beginning of the mRFP reporter gene connected to pSB4K5. Check out our vectormap if you are curious about the detailed primer design. The goal of this week was to amplify our previously assembled backbone with the intended overlaps as well as the desired genes from our host organism D. Acidovorans .
Week 11
During the past week we managed to amplify 11 kb as a single fragment including the genes DelA to DelF from genomic DNA from D. Acidovorans. Furthermore we were able to equip our biobrick backbone pSB4K5 with the desired overlaps to the genes of the Delftibactin cluster. We also succeeded in the amplification of the very last gene in our construct, DelL. However still a lot of work has to be done, since the amplification of DelF-G and DelO-P turned out to be more complicated. Since our initial plan, to amplify DelO-P with a Gibson primer which includes an overlaps to DelL and furthermore introduces an artificial ribosom binding site, turned out to be quite ambitious, we orderd shorter versions of all our Gibson primers, used to amplify genomic DNA. Using these shorter primers which should anneal better we will try to preamplify the desired genes in order to obtain a specific template for the amplification with the needed overlaps. Furthermore we will optimize the PCR conditions for the amplification of DelF-G.
Week 12
By the end of last week we decided that the short primers we had ordered in the previous week did not lead to any advantage in amplification of the missing genes from D. Acidovorans . Also the amplification of DelF-G did not proceed as expected. Additionly, further analysis of the Delftibactin cluster, led to the discovery of another putative promotor in front of DelO-P. Therefore we not only decided to design new primers for the region of DelFG but also modified the entire strategy and our construct in concerns of DelOP. To ensure the expression of DelOP in our target organism E.coli we decided to introduce this promotor in our final vector. Logically new primers were ordered for this region but as we still want to use Gibson cloning also the very last fragment of DelA-G has now to be amplified with an overlap, matching the promotor in front of DelOP. The correlating primers can be found in our new vector map.

- The amplification of FS_21 to FS_07 led to several bands, but none of these was the intended product
- The amplfication of FS_20 to FS_07 also led to several bands, one band at the right height was observed. Consequently the specificity of the PCR will be increased by a higher annealing temperature

Results:

- 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

Result:
- None of the screened colonies led to the correct amplicon, therefore the correct assembly has not worked in any of the white colonies
- screening will be repeated, with white colonies as template, as bacteria including the correct 32 kbp backbone might not be capable of expressing mRFP anymore due to the large insert between lac promotor and mRFP

Result:
- Colony D8w shows expected amplicon of 1.5kbp
- The other colonies were screened negative.
- D8w will be transfered to liquid culture to repeat screening PCR as well as for further validation beeing screening for the other insert fragments as well as test restriction digest
- Furthermore another electorporation will be carried out to yield more clones positive for screening with the Primers VR and FS_14, therefore the remaining 10µl of the Gibson assembly will be purified using isopropanol precipitation
Electroporation
We electroporated the Gibson assembly (15-08) again to increase the chance of a positive clone. We purified it by isopropanol purification.

Results:
- Sequencing of the final construct pFSN for all internal Gibson sites validated the intended sequence
- Sequence of mRFP shows mutations within the primer site, therefore it can be concluded that mRFP is not functional
- Colonies of D8w will be further analyzed by FACs to investigate whether mRFP is functional or not
- Additionaly, SDS-page of clone D8w will be conducted to check for expression of the inserted Del genes
- Concluding the results of colony PCRs, restriction digests and sequencing it can be concluded, that we successfully amplified 28 kbp of genomic DNA from our donator organism Delftia acidovorans SPH-1 distributed from the DSMZ, ligated the thereby obtained 6 fragments including the standard biobrick backbone pSB4K5 sucessfully in the intended order and consequently transformed a plasmid of 32 kbp in total into E. Coli using electroporation

- Another 8 ml of colony D8w (pFSN-1) were midi-preped according to protocol 'Preparation of large plasmids'.
