Abstract excerpt

Prokaryotic regulatory small RNAs act by a conserved mechanism and yet display a stunning structural variability. In the present study, we used mutational analysis to dissect the functional anatomy of RybB, a σ(E)-dependent sRNA that regulates the synthesis of major porins in Escherichia coli and Salmonella. Mutations in the chromosomal rybB locus that altered the expression of an ompC-lac fusion were identified....
