P1immStrain Comments: - This strain may also carry rfbD1.
- leuB6(Am)-- Suppressed by serU suppressor (supH)
- purE42-- :Strains with this marker are derivatives of Χ148 and may carry malA38LAMR and a suppressor of the Mal- phenotype, sup-78,near his.
- glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
- P1imm-- P1-immunity.
- glnX44(AS) was formerly called su+II
- glnX44(AS) was formerly called supE44
- glnX44(AS) was formerly called glnV44
- manA3 was formerly called man-1
- xyl-7 was formerly called xylA7
- Am = amber(UAG) mutation
- AS = amber(UAG) suppressor
- aziR = azide resistance
