Methyl-accepting chemotaxis protein PctA

UniProtKB accession:  G3XD24

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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. Major receptor that responds to all naturally occurring L-amino acids, except L-Gln and L-Asp. Also involved in repellent responses to trichloroethylene (TCE), chloroform and methylthiocyanate (PubMed:16233808, PubMed:23650915, PubMed:8522505, PubMed:9353923). Also mediates chemotaxis to histamine, but does not bind histamine (PubMed:30425146). In addition, binds the quorum-sensing signal autoinducer 2 (AI-2), thus inducing chemotaxis toward AI-2 and biofilm formation (PubMed:33097715).
