PhyR is a signal transduction response regulator found in Alphaproteobacteria with a C-terminal receiver domain (Pfam:PF00072) and extracytoplasmic function (ECF) sigma factor-like domain at the N-terminal which is represented in this entry [1-3]. PhyR is the regulator of the two-component signal transduction system which controls transcription in response to general stress.
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.
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].
