Multiple forms of methyl-accepting chemotaxis proteins distinguished by a factor in addition to multiple methylation.
Methyl-accepting chemotaxis proteins are central to both the excitation and adaptation phases of chemotactic behavior. Using null mutations in the genes coding for the two major methyl-accepting proteins (tsr and tar), we identified the gene products among the membrane proteins of Escherichia coli visualized on one- and two-dimensional gels. On two-dimensional gels, both the tsr and the tar pro...
متن کاملMethyl group turnover on methyl-accepting chemotaxis proteins during chemotaxis by Bacillus subtilis.
The addition of attractant to Bacillus subtilis briefly exposed to radioactive methionine causes an increase of labeling of the methyl-accepting chemotaxis proteins. The addition of attractant to cells radiolabeled for longer times shows no change in the extent of methylation. Therefore, the increase in labeling for the briefly labeled cells is due to an increased turnover of methyl groups caus...
متن کاملPosttranslational processing of methyl-accepting chemotaxis proteins in Escherichia coli.
Methyl-accepting chemotaxis proteins (MCPs) of Escherichia coli undergo changes in methylation state in response to chemical stimuli. The addition of methyl groups to MCP is dependent on cheR function; their removal is dependent on cheB function. This MCP methylation system is instrumental in establishing the unstimulated swimming pattern of E. coli and in enabling the cell to carry out sensory...
متن کاملEvolutionary conservation of methyl-accepting chemotaxis protein location in Bacteria and Archaea.
The methyl-accepting chemotaxis proteins (MCPs) are concentrated at the cell poles in an evolutionarily diverse panel of bacteria and an archeon. In elongated cells, the MCPs are located both at the poles and at regions along the length of the cells. Together, these results suggest that MCP location is evolutionarily conserved.
متن کاملA methyl-accepting protein is involved in benzoate taxis in Pseudomonas putida.
Pseudomonas putida is attracted to at least two groups of aromatic acids: a benzoate group and a benzoylformate group. Members of the benzoate group of chemoattractants stimulated the methylation of a P. putida polypeptide with an apparent molecular weight of 60,000 in sodium dodecyl sulfate-polyacrylamide gels. This polypeptide is presumed to be a methyl-accepting chemotaxis protein for severa...
