Strain Comments:

• 1.Please note this correction of a detail in the plasmid description in the
• 2.reference below. The plasmid was cut with AvaI and EcoRV, rather than EcoRI and HindIII as stated on p. 9591, for insertion of the suppressor gene into pACYC184.
• lacZ82(Am)-- comes from strain Hfr 3000 X82. It is an amber mutation.
• Δ(kdpC-kdpA)18-- deletion has been called kdpABC5.
• 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
• AS* = synthetic amber suppressor mut
