Strain Designation: CAJ64      Source of Strain: Sambrook
Sex: F- Chromosomal Markers: Δ(codB-lacI)3, relA1, spoT1, trpT171(UGAs)
Strain Comments:

• Δ(codB-lacI)3-- is a deletion of the entire lac operon, from the strain Hfr 3000 X74 of Jacob. Refs. on extent of deletion: Sung et al.1987,J.Bact.169:2639; Gerdes et al.2001
• Δ(codB-lacI)3-- Shown by Ferrandez et al. 1997 to extend to mhpD
• Δ(codB-lacI)3-- Shown by Durfee et al. to extend from codon 292 of yahG through mhpE
• spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
• Δ(codB-lacI)3 was formerly called Δlac74
• Δ(codB-lacI)3 was formerly called Δ(lac)3
• Δ(codB-lacI)3 was formerly called Δ(yahG-mhpE)
