Design Notes

  • HisB KO: 6 nucleotides (694-699) coding for amino acids V and E were deleted using MAGE.
  • PyrF KO: Two early in-frame stop codons were made using MAGE to substitute 8T-->A and 16C-->G
  • rpoZ KO: Lambda red was used to replace gene with Zeocin resistance cassette.
  • Kanamycin resistance cassette—Zif268 binding site and weak promoter—His3—URA3: inserted into 1529620 genomic locus using lambda red.
  • MutS KO: replaced by chloramphenicol resistance cassette.

Base strain was EcNR2, a modified E. coli strain as described in Wang et al (2009).

URA3 and His3 genes were synthesized.
