creC510Strain Comments: - W1895 is a stable clone of the Cavalli Hfr isolated in the Lederberg laboratory
- spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
- creC510-- The constitutive phenotype is due to an R77P amino acid substitution
- creC510 was formerly called phoM510
- Const = constitutive
