Design Notes
we isolated norM from the genomic sequence of shewanella oneidensis MR-1. We designed our primers in a way that enabled us to use Gibson Assembly to ligate the norM gene with pSB1C3. Insofar, we designed four primers to generate homologous overlaps between pSB1C3 and norM:
- norM_fwd
GAATTCGCGGCCGCTTCTAGATGAAACATTCAGGCTTTCAAGCCAAAC - norM_rev
CTGCAGCGGCCGCTACTAGTATTAATGGTGCACGCTGTCGCCTTC - norM_fwd
GAATTCGCGGCCGCTTCTAGATGAAACATTCAGGCTTTCAAGCCAAAC - norM_rev
CTGCAGCGGCCGCTACTAGTATTAATGGTGCACGCTGTCGCCTTC
- norM_fwd
we eliminated one illegal restriction site: Therefore we substituted one base in the illegal restriction site by using PCR. The designed PCR-primers generated homologue overlaps, thus enabling Gibson Assembly afterwards:
- Pst1 at 234 bp (changing CTGCA^G to CTGtAG)
- Pst1 at 1644 bp (changing CTGCA^G to CTGtAG)
- EcoR1 at 1840 bp (changing G^AATTC to GAATTt)
These primers were used to eliminate the illegal restriction sites:
- pst1-234 fwd (38 bp)
