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)
• aer-3075::Tn10-- : insertion shown by PCR (Nichols et al. 1998) to be within aer, at nucleotide 3,215,934 (69.321 min.).
• aer-3075::Tn10 was formerly called zgj-3075::Tn10

• rfbC1 was formerly called rfbD1
• thiE1 was formerly called thi-1
• = tetracycline resistant
• Am = amber(UAG) mutation
• AS = amber(UAG) suppressor
