Protein Family Models

Rsbr is a regulator of the RNA polymerase sigma factor subunit sigma(B). The structure of the N terminal domain belongs to the globin fold superfamily [1]. [1]. 16301540.

The STAS (after Sulphate Transporter and AntiSigma factor antagonist) domain is found in the C terminal region of Sulphate transporters and bacterial antisigma factor antagonists. It has been suggested that this domain may have a general NTP binding function [2]. [1]. 9560229.

RsbT co-antagonist protein RsbRA functions in the environmental signaling branch of the general stress response; acts as a positive regulator of sigma-B activity in response to salt and heat stress by stimulating the activity of the RsbT kinase toward RsbS
