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


we eliminated one illegal restriction site: Therefore we substituted one base in the illegal restriction site by using PCR. The designed PCR-primers generated homologous overlaps, thus enabling Gibson Assembly afterwards:

  • Pst1 at 929 bp (changing CTGCA^G to CTGtAG)

These primers were used to eliminate the illegal restriction site:

  • pst1 norM fwd
    GCGATCGTGCTGATATTTCTGCGGTGGTCGCCAAAGTC
  • pst1 norM rev
