creC510Strain Comments: - Δ(argF-lac)169-- extends from mmuP through orfs preceding argF, through lac to mhpD, literally Δ(mmuP-mhpD)169. (Peters et al. 2003 JB 185:2017)
- Δ(argF-lac)169-- from strain Hfr3000 U169 was initially called ΔlacU169 and described as a lacZY mutation until found to include argF and lacI.
- recA1-- : Missense mutation, altered isoelectric point. Sequenced: G to A for Nuc. 720 (Gly 160 Asp).
- rph-1-- is a 1 bp deletion that results in frameshift over last 15 codons and has polar effect on pyrE leading to suboptimal pyrimidine levels on minimal medium.(Jensen 1993 JBact.175:3401)
- creC510-- The constitutive phenotype is due to an R77P amino acid substitution
- creC510 was formerly called phoM510
- Am = amber(UAG) mutation
- Const = constitutive
- ApR = ampicillin resistant
