Obg, an essential GTP binding protein of Bacillus subtilis, is necessary for stress activation
of the ςB transcription factor. We investigated Obg's cellular associations by differential …

In 1992, we described the cloning and sequencing of the dnaK locus of Bacillus subtilis
which, together with transcriptional studies, implied a tetracistronic structure of the operon …

The expression of the gsiB gene of Bacillus subtilis in response to a wide variety of stress
conditions was analysed, and the results provide evidence that gsiB is subject to a σ B …

sigma B is a secondary sigma factor of Bacillus subtilis. sigma B-dependent transcription is
induced when B. subtilis enters the stationary phase of growth or is exposed to any of a …

Bacteria respond to physical and chemical stresses that affect the integrity of the cell wall
and membrane by activating an intricate cell envelope stress response. The ability of cells to …

The sigB operon of Bacillus subtilis encodes sigma B and three additional open reading
frames (orfV, orfW, and orfX). Having previously mapped several mutations that alter the …

Bacteria need dedicated systems that allow appropriate adaptation to the perpetual changes
in their environments. In Bacillus subtilis, two HtrA-like proteases, HtrA and HtrB, play critical …

In this paper we have defined proteome signatures of Bacillus subtilis in response to heat,
salt, peroxide, and superoxide stress as well as after starvation for ammonium, tryptophan …

RsbU is a positive regulator of the activity of σ B, the general stress-response σ factor of
Gram+ microorganisms. The N-terminal domain of this protein has no significant sequence …

Exogenously provided proline has been shown to serve as an osmoprotectant in Bacillus
subtilis. Uptake of proline is under osmotic control and functions independently of the known …
