Function

MCP2_SALTY Receptor for the attractant L-aspartate and related amino and dicarboxylic acids. Tar mediates taxis away from the repellents cobalt and nickel. Unlike in E.coli tar, it does not mediates maltose taxis. Chemotactic-signal transducers respond to changes in the concentration of attractants and repellents in the environment, transduce a signal from the outside to the inside of the cell, and facilitate sensory adaptation through the variation of the level of methylation. Attractants increase the level of methylation while repellents decrease the level of methylation, the methyl groups are added by the methyltransferase CheR and removed by the methylesterase CheB.
