Strain Comments:

• This is a spontaneous leu⁺ revertant of AB2463.
• 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.
• recA13-- Amino acid substitution Leu 51 Phe
• 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
• AS = amber(UAG) suppressor
• Oc = ochre(UAA) mutation
• strR = streptomycin resist.
