| '''Response regulators''' (RR) are part of the two-component signal transduction systems which enable bacteria to sense and respond to a wide range of environments. | | '''Response regulators''' (RR) are part of the two-component signal transduction systems which enable bacteria to sense and respond to a wide range of environments. |
| Two-component RR is a complex of histidine kinase (sensor protein SP) and RR. The RR act as phosphorylation-activated switches. Most RR consist of N terminal shich is the signal receiving domain and C terminal which is the DNA-binding domain. | | Two-component RR is a complex of histidine kinase (sensor protein SP) and RR.
