GUC49      Source of Strain:
F- Chromosomal Markers: thr-1
, CbiStrain Comments:
- Does not excrete substantially more enterochelin than does parent strain C600. CBI = colicin B insensitive = not exb-.
- leuB6(Am)-- Suppressed by serU suppressor (supH)
- glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
- Cbi-- - Colicin B insensitive phenotype
- glnX44(AS) was formerly called supE44
- glnX44(AS) was formerly called su+II
- 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
