Coexpression patterns of sigma(B) regulators in Bacillus subtilis affect sigma(B) inducibility.

abstract：:We used Southern blotting to screen a variety of bacterial genes for homology to the kdp genes of Escherichia coli, genes that encode an ATP-driven K+ transport system. We found that most enterobacteria have sequences homologous to those of the three kdp structural genes and the kdpD regulatory gene. A number of dista...
