Strain Designation: MA255      Source of Strain: W.K. Maas
Sex: F- Chromosomal Markers: thr-1, leuB6(Am), fhuA2::IS2, lacY1, glnX44(AS), gal-6, λ^-, relA1, CanR?-1, speB2, speC3, rpsL133(strR), xyl-7, mtlA2, 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)
• CanR?-1-- This is a mutation that results in canavanine resistance and maps near argP, but does not affect arginine transport.
• CanR?-1 was formerly called can-1
• fhuA2::IS2 was formerly called fhuA2
• 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
• xyl-7 was formerly called xylA7
• ::IS2 = Insertion of IS2
• Am = amber(UAG) mutation
• AS = amber(UAG) suppressor
• strR = streptomycin resist.
