'''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.
