CGSC Strain#: 6130
Strain Designation: W3160      Source of Strain: M.L. Morse
Sex: F- Chromosomal Markers: galK2(Oc), rph-1
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.
• rph-1-- is a 1 bp deletion that results in frameshift over last 15 codons and has polar effect on pyrE leading to suboptimal pyrimidine levels on minimal medium.(Jensen 1993 JBact.175:3401)
• galK2(Oc) was formerly called gal₂
• Oc = ochre(UAA) mutation
