F- Chromosomal Markers: thr-1
- leuB6(Am)-- Suppressed by serU suppressor (supH)
- 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.
- sulA211-- was formerly called sfiA11.
- recA441(ts)-- formerly tif-1 (temp.-induced filamentation). Not a Rec- phenotype, "constitutive protease activity" not requiring ss-DNA binding at hi temp.
- lexA3(Ind-)-- : Non-cleavable LexA repressor protein; defective in SOS induction, UV sensitive
- 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
- rfbC1 was formerly called rfbD1
- Am = amber(UAG) mutation
- AS = amber(UAG) suppressor
- Ind- = non-inducible
- Oc = ochre(UAA) mutation
- strR = streptomycin resist.
- ts = Temperature Sensitive
