, creC510Strain Comments:
- phoA8 is a deletion.
- glpD10-- : Loss of G-3-P dehydrogenase (aerobic) results in inability of strains to grow on glycerol or glycerol-3-P as sole carbon source.
- glpD10-- : Loss also results in stasis with gluconeogenic C sources, e.g., succinate. glpA or glpD mutants should be grown on min.salts+1% glycerol-free casein hydrolysate+1% glucose
- spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
- rrnB-2-- : loss of spacer loop sequence
- creC510-- The constitutive phenotype is due to an R77P amino acid substitution
- creC510 was formerly called phoM510
- Const = constitutive
- T2R = T2 Resistant
