Strain Comments: - 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.
- galK2(Oc) was formerly called gal2
- Chi- = lacks only Chi activity
- Oc = ochre(UAA) mutation
- strR = streptomycin resist.
- ts = Temperature Sensitive
