Abstract excerpt
The general stress regulon of Bacillus subtilis is induced by activation of the sigma(B) transcription factor. sigma(B) activation occurs when one of two phosphatases responds to physical or nutritional stress to activate a positive sigma(B) regulator by dephosphorylation. The signal that triggers the nutritional stress phosphatase (RsbP) is unknown; however, RsbP activation occurs under culture conditions...
