mcpQ

Methyl-accepting chemotaxis protein McpQ

638 amino acids

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. McpQ recognizes specifically citrate and citrate/metal(2+) complexes. Binds citrate/metal(2+) complexes with higher affinity than free citrate, and mediates preferentially chemotaxis toward citrate/metal(2+) complexes.
