UniProt functional annotation for P07363

UniProt code: P07363.

Organism: Escherichia coli (strain K12).
Taxonomy: Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia.
 
Function: 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.
 
Catalytic activity: Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L- histidine.; EC=2.7.13.3;
Subunit: An in vitro complex of CheW/CheA(L)/CheA(S) in a 1:1:1 ratio increases the autophosphorylation of CheA and is required for the binding of CheY, the phosphorylation substrate. This complex accounts for 10% of the total number of molecules. {ECO:0000269|PubMed:2068106}.
Subcellular location: Cytoplasm.
Domain: May have three functional domains: one for interaction with CheB and CheY, a second for regulating phosphorylation and controlling the stability of the protein, and a third for receiving input signals regulating CheA activity. {ECO:0000269|PubMed:2832069}.
