Strain Designation: AB378      Source of Strain: A.L. Taylor
Sex: Hfr    Point of Origin#:    Map Position: Chromosomal Markers: thr-1, leuB6(Am), lacZ4, glnX44(AS), λ^-, rfbC1, purF1, rpsL8, cysE8, 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)
• purF1-- is a very stable mutation and may be an intragenic deletion.
• cysE8-- mutant grows on L-cysteine, has low reversion rate.
• cysE8 was formerly called cysA8
• glnX44(AS) was formerly called su⁺_II
• glnX44(AS) was formerly called supE44
• glnX44(AS) was formerly called glnV44
• rfbC1 was formerly called rfbD1
• thiE1 was formerly called thi-1
• Am = amber(UAG) mutation
• AS = amber(UAG) suppressor
