Chromosomal Markers: araC14, leuB6(Am), fhuA2, Δ(gpt-proA)62, lacY1, glnV44(AS), galK2(Oc), λ^-, rpsL20(strR), xylA5, mtl-1, thiE1, [hsdS20]
Strain Comments:

• leuB6(Am)-- Suppressed by serU suppressor (supH)
• 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.
• [hsdS20]-- : at least [ thr-hsd] comes from E. coli B. r^-_B m^-_B.
• Δ(gpt-proA)62 was formerly called proA2
• galK2(Oc) was formerly called gal₂
• glnV44(AS) was formerly called supE44
• glnV44(AS) was formerly called su⁺_II
• thiE1 was formerly called thi-1
• Am = amber(UAG) mutation
• AS = amber(UAG) suppressor
• Oc = ochre(UAA) mutation
• strR = streptomycin resist.
