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 which is the signal receiving domain and C terminal which is the DNA-binding domain (DBD). RR CheY is a chemotaxis response regulator in bacteria. RR Spo0 is the sporulation response regulator. RR PleD is required in loss of motility. For details see PleD activation, PleD allosteric product inhibition, PleD catalysis and Response regulator PLED in complex with C-di-GMP RR PhoP is important for survival under conditions of macrophage-induced stress. For details see PhoP Regulatory Domain and PhoP-PhoQ Photosynthetic apparatus RR in Rhodobacter sphaeroides is involved in the transduction of signals which monitor oxygen levels. . For details see PrrA in Rhodobacter sphaeroides RR WspR couples the chemosensory Wsp pathway to the overproduction of acetylated cellulase . For details see WspR. Redox RR is DNA-sequence specific. It controls transcription as a result of its phosphorylation by a redox sensor.
