A	PF00072	Response regulator receiver domain (Response_reg)	Response regulator receiver domain	This domain receives the signal from the sensor partner in bacterial two-component systems. It is usually found N-terminal to a DNA binding effector domain.	Domain
A	PF22029	Sigma2 domain of PhyR (PhyR_sigma2)	Sigma2 domain of PhyR	This is the N-terminal domain of response regulator PhyR and related proteins. It consists of three alpha-helices and together with sigma4 constitutes the PhyR sigma-like (SL) domain. This domain was shown to bind to anti-sigma factor NepR [1].	Domain
