Notes

BW25113 is a derivative of the F-, λ-, E. coli K-12 strain BD792 (CGSC6159)[1], which is a derivative of E. coli K-12 W1485. According to the CGSC, BD792 carries rpoS396(Am), but this mutation is not listed in the published genotype for BW25113, as according to Baba 2006 [2], a pseudoreversion rpoS (Q33) allele was transferred from MG1655 into a predecessor of BW25113.


BW25113 was used to make the Keio Collection of single-gene knockouts. [2] [1] Available from the Coli Genetics Stock Center: CGSC#7636 The genotype for BW25113 in Datsenko et al. [1] said the strain is lacIQ, but it was later shown to be lacI+ Baba et al. (Supplementary Table 1)[2].

According to the CGSC, lacZ4787(del) has 4 tandem copies of the rrnB transcriptional terminator inserted by gene replacement into the region extending from near the SacII site near the N-terminus of lacZ through the promoter.
