CGSC Strain#: 6331
Strain Designation: W4573      Source of Strain: J. Lederberg
Sex: F- Chromosomal Markers: araC14, Δlac-85, glnX44(AS), galK2(Oc), rpsL197(strR), malT1(λ^R), xylA5, mtl-1
Strain Comments:

• glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
• 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
• glnX44(AS) was formerly called su⁺_II
• glnX44(AS) was formerly called supE44
• glnX44(AS) was formerly called glnV44
• AS = amber(UAG) suppressor
• LamR = Lambda-resistant
• Oc = ochre(UAA) mutation
• strR = streptomycin resist.
