title: Multiple controls exerted on in vivo expression of the pepN gene in Escherichia coli: studies with pepN-lacZ operon and protein fusion strains.
abstract: Three physiological conditions were shown to promote transcriptional regulation of pepN expression: phosphate limitation, the nature of the source of carbon and energy, and anaerobiosis. The transcriptional level of regulation can be deduced from the observation of these effects in strains carrying operon fusion pepN-lacZ. Mutations in the various genes phoB, phoM, phoR, crp, and fnr (oxrA) did not affect pepN expression.
