Protein

Chemotaxis response regulator protein-glutamate methylesterase

Gene

cheB

Organism
Clostridium acetobutylicum (strain ATCC 824 / DSM 792 / JCM 1419 / LMG 5710 / VKM B-1787)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Involved in the modulation of the chemotaxis system; catalyzes the demethylation of specific methylglutamate residues introduced into the chemoreceptors (methyl-accepting chemotaxis proteins) by CheR.UniRule annotation

Catalytic activityi

Protein L-glutamate O5-methyl ester + H2O = protein L-glutamate + methanol.UniRule annotation
