CGSC Strain#: 6786
Strain Designation: MM152      Source of Strain: M. Meselson
Other Designations: M152
Other Designations: N100
Sex: F- Chromosomal Markers: galK2(Oc), λ^-, recA3, IN(rrnD-rrnE)1, rpsL200(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.
