Protein
Chemotaxis protein CheA
Gene
cheA, TM_0702
Organism
Thermotoga maritima (strain ATCC 43589 / MSB8 / DSM 3109 / JCM 10099)
Status
Reviewed - Annotation score: 2 out of 5 - Experimental evidence at protein leveli

Functioni

Involved in the transmission of sensory signals from the chemoreceptors to the flagellar motors. CheA is autophosphorylated; it can transfer its phosphate group to either CheB or CheY By similarity.

Catalytic activityi

ATP + protein L-histidine = ADP + protein N-phospho-L-histidine.
