Protein

Chemoreceptor McpA

Gene
mcpA, CC_0430
Organism
Caulobacter crescentus (strain ATCC 19089 / CB15)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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.
