| MCPs | Methyl accepting chemotaxis proteins. Proteins of the inner cytoplasmic face of the bacterial plasma membane with which the receptors of the outer face interact. Four different MCPs are known in E. Coli, each with a separate set of receptors. Can be methylated at various sites, methylation is part of the adaptation to the signal. Although important intermediate signal integration sites, they are not directly connected to the motor. (18 Nov 1997) |
