Strain Comments:

• 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
• rpoC4(ts)-- is a temperature-senstive mutation.
• fhuA2::IS2 was formerly called fhuA2

• glnX44(AS) was formerly called su⁺_II
• glnX44(AS) was formerly called supE44
• thiE1 was formerly called thi-1
• xyl-7 was formerly called xylA7
• ::IS2 = Insertion of IS2
• AS = amber(UAG) suppressor
• L? = assignment uncertain
• LamR = Lambda-resistant
• ts = Temperature Sensitive
