Extracytoplasmic Function σ Factors Regulate Expression of the <i>Bacillus subtilis yabE</i> Gene via a <i>cis</i> -Acting Antisense RNA

Abstract

Bacillus subtilis yabE encodes a predicted resuscitation-promoting factor/stationary-phase survival (Rpf/Sps) family autolysin. Here, we demonstrate that yabE is negatively regulated by a cis-acting antisense RNA which, in turn, is regulated by two extracytoplasmic function sigma factors: sigma(X) and sigma(M).
