Term Name phosphorelay sensor kinase activity
Term Accession GO:0000155
Aspect molecular_function
Synonyms (3) two-component sensor activity, two-component sensor molecule, two-component system sensor activity
Definition Catalysis of the phosphorylation of a histidine residue in response to detection of an extracellular signal such as a chemical ligand or change in environment, to initiate a change in cell state or activity. The two-component sensor is a histidine kinase that autophosphorylates a histidine residue in its active site. The phosphate is then transferred to an aspartate residue in a downstream response regulator, to trigger a response.
