Strain Comments: - This strain is a P2 eductant.
- lacZ2286(Am)-- is a UAG mutation in the first segment of the lacZ gene (Zipser et al., 1970).
- trpA49(Am)-- is the amber mutation formerly called trp-8am by Brenner.
- rpsL150(strR)-- T to C transition mutation resulting in a K43R amino acid substitution.
- Am = amber(UAG) mutation
- strR = streptomycin resist.
