?cl39097: MCP_signal Superfamily (this model, PSSM-Id:393467 is obsolete)
Methyl-accepting chemotaxis protein (MCP), signaling domain Methyl-accepting chemotaxis proteins (MCPs or chemotaxis receptors) are an integral part of the transmembrane protein complex that controls bacterial chemotaxis, together with the histidine kinase CheA, the receptor-coupling protein CheW, receptor-modification enzymes, and localized phosphatases. MCPs contain a four helix trans membrane region, an N-terminal periplasmic ligand binding domain, and a C-terminal HAMP domain followed by a cytoplasmic signaling domain. This C-terminal signaling domain dimerizes into a four-helix bundle and interacts with CheA through the adaptor protein CheW.
