| Term | phosphorelay sensor kinase activity | ID (Ontology) | GO:0000155 (Gene Ontology) |
| 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.[ PubMed:10966457 PubMed:20223701 PubMed:31386843 PubMed:9191038 ] | ||
