W. ArberOther Designations:
F- Chromosomal Markers: leuB6
, lacY1 or Δ(cod-lacI)6
, hsdR13Strain Comments:
- This is a K-12 derivative which has received the hsd- deoB region from E. coli 15. This strain is r-A m+A.
- leuB6(Am)-- Suppressed by serU suppressor (supH)
- glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
- glnX44(AS) was formerly called supE44
- glnX44(AS) was formerly called su+II
- glnX44(AS) was formerly called glnV44
- thiE1 was formerly called thi-1
- Am = amber(UAG) mutation
- AS = amber(UAG) suppressor
