- 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.
- glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
- deoR481-- A selectable phenotype of deoR mutants includes the ability to grow preferentially on minimal medium with inosine as the sole carbon source.
- gyrA96(NalR)-- resistant to 200ug/ml nalidixic acid
- gyrA96(NalR)-- GAC to AAC at codon 87
- recA1-- : Missense mutation, altered isoelectric point. Sequenced: G to A for Nuc. 720 (Gly 160 Asp).
- endA1-- G to A transition mutation resulting in E208K amino acid substitution.
- glnX44(AS) was formerly called glnV44
