CC -!- FUNCTION: Mediates chemotaxis towards five attractant amino acids
CC (leucine, isoleucine, valine, methionine and cysteine). Probably
CC transduces the signal from the substrate-binding protein BasB to the
CC histidine kinase CheA. {ECO:0000269|PubMed:10672186,
CC ECO:0000269|PubMed:12006484}.
CC -!- SUBUNIT: Interacts with CheA, CheY, CheW1 and CheW2.
CC {ECO:0000269|PubMed:23171228}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:10672186};
CC Multi-pass membrane protein {ECO:0000269|PubMed:10672186}.
CC -!- PTM: Methylated by CheR. {ECO:0000269|PubMed:10672186,
CC ECO:0000269|PubMed:18514223}.
CC -!- DISRUPTION PHENOTYPE: Mutants completely lose the chemotactic response
CC towards leucine, isoleucine, valine, methionine and cysteine, but they
CC still respond to arginine. {ECO:0000269|PubMed:10672186,
CC ECO:0000269|PubMed:12006484}.
CC -!- SIMILARITY: Belongs to the methyl-accepting chemotaxis (MCP) protein
CC family. {ECO:0000305}.
