| Accession | GenProp0762 | |
| Name | chemotaxis response-regulator system | |
| Type | SYSTEM | |
| Description | This property describes chemotaxis response-regulator systems as typified in Escherichia coli, with the histidine kinase CheA, the response regulator CheY, a phosphatase (CheZ in E. coli), and other proteins (CheB, CheW, and CheR in E. coli). This system also requires chemoreceptors, but these may be different in different species and are not currently included. | |
