Strain Comments: - The mutation coaA1, originally called rts-1, confers temperature-sensitivity on this strain. The mutation ilu-1 confers a temperature-sensitive requirement for isoleucine.
- leuB6(Am)-- Suppressed by serU suppressor (supH)
- glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
- hisG1-- This mutation has been reported as either a frameshift or a 36 nt deletion
- coaA1(ts)-- : C-to-T transition at nucleotide 976 of GenBank M90071 changes Leu codon CTT to Phe codon TTT in amino acid 236 of the long form (L236F). Siri, Westaway, and Hayflick, Personal Communication.
- coaA1(ts) was formerly called rts-1
- fhuA2::IS2 was formerly called fhuA2
- glnX44(AS) was formerly called su+II
- glnX44(AS) was formerly called supE44
- glnX44(AS) was formerly called glnV44
- xyl-7 was formerly called xylA7
- ::IS2 = Insertion of IS2
- Am = amber(UAG) mutation
- AS = amber(UAG) suppressor
- L? = assignment uncertain
- LamR = Lambda-resistant
- ts = Temperature Sensitive
