, thiE1Strain Comments:
- e14--- : Loss of the e14 element makes the strain McrA-.
- serA6-- grows well on 100ug/ml Ser and poorly on 20ug/ml, serA6 is tight. (In JC158).
- spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
- lacI22 was formerly called lacI3
- lacI22 was formerly called laci3-
- thiE1 was formerly called thi-1
