Bm. Pruss et al., THE ESCHERICHIA-COLI FLAGELLAR TRANSCRIPTIONAL ACTIVATOR FLHD REGULATES CELL-DIVISION THROUGH INDUCTION OF THE ACID RESPONSE GENE CADA, Journal of bacteriology, 179(11), 1997, pp. 3818-3821
FlhD is a positive regulator of cadA. A mutant with a transposon-media
ted lacZ fusion to cad4 exhibited a cell division phenotype similar to
that of the flhD mutant and had FlhD-dependent beta-galactosidase act
ivity. Under different growth conditions, the cell division rate corre
lated with the level of expression of cadA.
