AW824      Source of Strain:
F- Chromosomal Markers: relA1
, creC510Strain Comments:
- Revertant of hemG mutant AW824, with no accumulation of porphyrins, and no tumbling response to blue light. Control for AW823.
- 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
- = kanamycin resistant
- Const = constitutive
