Abstract

In the bacterium Bacillus subtilis (Bs), the alternative transcription factor sigma B is activated by environmental stresses to control the expression of a large set of unlinked genes. However, the range of physiological functions mediated by these sigma B-controlled genes is presently unknown. We report here that the newly identified gene csbB is under the dual control of a sigma B-dependent and a sigma B-independent promoter. The predicted product of csbB is a 329 residue protein containing two potential membrane-spanning segments in its C-terminal region, leading us to speculate that one class of sigma B-controlled genes acts to modify the cell envelope as part of the general stress response.
