Strain Comments:

• lacZ125(Am)-- is the amber mutation from Zipser's strain NG125 and Brenner's CA274. It was formerly called lac_125am by Brenner. In `interval 6' of Newton et al. JMB 14:290 (1965).
• asnB507::Tn10-- cotransduces 47% with supE.
• e14--- : Loss of the e14 element makes the strain McrA^-.
• trpA49(Am)-- is the amber mutation formerly called trp^-_8am by Brenner.
• spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
• = tetracycline resistant
• Am = amber(UAG) mutation
