- galK2(Oc)-- is a GAA(glu) to TAA(ochre) mutation, residue 134. Oller et al.1993. Apparently non-suppressible, since all revertants found were at the ochre site.
- purB93(ts)-- has a Ts requirement for adenine and an antimutator phenotype (resistance to MNNG and other alkylating agents).
- Δ(gpt-proA)62 was formerly called proA2
- galK2(Oc) was formerly called gal2
- glnV44(AS) was formerly called supE44
- glnV44(AS) was formerly called su+II
- purB93(ts) was formerly called mud
- rfbC1 was formerly called rfbD1
- thiE1 was formerly called thi-1
- AS = amber(UAG) suppressor
- LamR = Lambda-resistant
- Oc = ochre(UAA) mutation
- strR = streptomycin resist.
- ts = Temperature Sensitive
