deo-27 or deo-43Strain Comments: -  deo-27 is  deoB or  deoC.  This strain is φX-sensitive but plates φX poorly with turbid plaques.  This is an  E. coli K-12 x C hybrid.
- glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
- endA1-- G to A transition mutation resulting in E208K amino acid substitution.
- glnX44(AS) was formerly called su+II
- glnX44(AS) was formerly called supE44
- glnX44(AS) was formerly called glnV44
- thiE1 was formerly called thi-1
-  = good miniprep dsDNA quality
- AS = amber(UAG) suppressor
