Abstract: In Escherichia coli and Salmonella enterica, RyeA and RyeB RNAs are encoded on opposite DNA strands at the same locus. We present evidence indicating that the last 23 bp of the ryeB gene, corresponding to an internal portion of the ryeA gene, served repeatedly as the integration site for exogenous DNA during Salmonella evolution and still act as an attachment site for present-day bacteriophages. Interestingly, ryeA sequence and expression are modified upon lysogenization.
