CGSC Strain#: 14187
Strain Designation: 594 λ cI857 Sam7      Source of Strain: F. Stahl
Sex: F- Chromosomal Markers: lac-3350, galK2(Oc), galT22, λ[cI857 Sam7], IN(rrnD-rrnE)1, rpsL179(strR)
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.
• IN(rrnD-rrnE)1-- Inverts the region between rrnD (73.74 min) and rrnE (90.66 min)
• galK2(Oc) was formerly called gal₂
• Oc = ochre(UAA) mutation
• strR = streptomycin resist.
