Epigenetic phase variation of the pap operon in Escherichia coli.
Expression of the pyelonephritis-associated pilus (pap) operon in Escherichia coli is regulated by a complex epigenetic phase-variation mechanism involving the formation of differential DNA-methylation patterns. This review discusses how DNA-methylation patterns are formed by protein-DNA interactions and how methylation patterns, in turn, control pap gene expression.
