Abstract
The bvg locus of Bordetella pertussis, required for coordinate regulation of virulence genes in response to environmental signals, encodes two proteins, BvgS and BvgA, that belong to the bacterial two-component signal transduction systems. We have isolated spontaneous mutations of the bvg locus in Escherichia coli and analyzed their effects on the expression of fhaB::lacZY transcriptional fusions. The mutations, localized in the linker and transmitter domain of BvgS, result in increased activation of fhaB and/or in insensitivity to a modulating agent, nicotinic acid.Entities:
