The three adaptation systems of Bacillus subtilis chemotaxis.
Adaptation has a crucial role in the gradient-sensing mechanism that underlies bacterial chemotaxis. The Escherichia coli chemotaxis pathway uses a single adaptation system involving reversible receptor methylation. In Bacillus subtilis, the chemotaxis pathway seems to use three adaptation systems. One involves reversible receptor methylation, although quite differently than in E. coli. The oth...
متن کاملPermeabilization of Bacillus subtilis to Chemotaxis
The net methylation of methyl-accepting chemotaxis proteins (MCPs) is the biochemical manifestation of physiological adaptation to amino acid chemoattractants by Escherichia coli (4). In Bacillus subtilis, demethylation of MCPs occurs during such adaptation (3). The activity of chemotaxis methyltransferase is detectable in vivo and in vitro. As an alternative assay, whole cells can be permeabil...
متن کاملPhosphorylation of the response regulator CheV is required for adaptation to attractants during Bacillus subtilis chemotaxis.
In the Gram-positive soil bacterium Bacillus subtilis, the chemoreceptors are coupled to the central two-component kinase CheA via two proteins, CheW and CheV. CheV is a two-domain protein with an N-terminal CheW-like domain and a C-terminal two-component receiver domain. In this study, we show that CheV is phosphorylated in vitro on a conserved aspartate in the presence of phosphorylated CheA ...
متن کاملSelective methylation changes on the Bacillus subtilis chemotaxis receptor McpB promote adaptation.
The Bacillus subtilis McpB is a class III chemotaxis receptor, from which methanol is released in response to all stimuli. McpB has four putative methylation sites based upon the Escherichia coli consensus sequence. To explore the nature of methanol release from a class III receptor, all combinations of putative methylation sites Gln(371), Gln(595), Glu(630), and Glu(637) were substituted with ...
متن کاملAdaptation of Bacillus subtilis to oxygen limitation.
Bacillus subtilis grows anaerobically by at least two different pathways, respiration using nitrate as an electron acceptor and fermentation in the absence of electron acceptors. Regulatory mechanisms have evolved allowing cells to shift to these metabolic capabilities in response to changes in oxygen availability. These include transcriptional activation of fnr upon oxygen limitation, a proces...
