Strain Comments:

• Δ(gpt-lac)5-- is the deletion Δ( pro-lac)_X111 of Jacob and originated in the strain Hfr 3000 X111.
• argE-(Am)-- is suppressible by all of the characterized amber and ochre suppressors in Miller et a. 1977
• thiE1 was formerly called thi-1
• Am = amber(UAG) mutation
• NalR = Nalidix.acidResist.
• rifR = rifamycin resistance
• ApR = ampicillin resistant
• AS* = synthetic amber suppressor mut
