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. RR CheY is a chemotaxis response regulator in bacteria. RR Spo0 is the sporulation response regulator. For details see:
For PleD:
- PleD activation
- PleD allosteric product inhibition
- PleD catalysis
- Response regulator PLED in complex with C-di-GMP
For PhoP:
For photosynthetic apparatus RR:
For WspR RR:
