Strain Designation: GM2159      Source of Strain: M.G. Marinus
Sex: F- Chromosomal Markers: thr-1, araC14, leuB6(Am), Δ(gpt-proA)62, lacY1, tsx-33, glnX44(AS), galK2(Oc), λ^-, hisG4(Oc), rpsL31(strR), dam-13::Tn9, xylA5, mtl-1, recF143, argE3(Oc), thiE1
Strain Comments:

• leuB6(Am)-- Suppressed by serU suppressor (supH)
• 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.
• dam-13::Tn9-- There have been some reports that growing strains with this marker without chloramphenicol can lead to dam+ revertants
• Δ(gpt-proA)62 was formerly called proA2
• galK2(Oc) was formerly called gal₂
• glnX44(AS) was formerly called glnV44
• glnX44(AS) was formerly called su⁺_II
• glnX44(AS) was formerly called supE44
• thiE1 was formerly called thi-1
• = chloramphenicol resistant
• Am = amber(UAG) mutation
• AS = amber(UAG) suppressor
• Oc = ochre(UAA) mutation
• strR = streptomycin resist.
