• Protein family:

• Paralogous protein(s): RsbRB, RsbRC, RsbRD, YtvA

Extended information on the protein

• Kinetic information:

• Domains: RsbRA is composed of an N-terminal nonheme globin domain and a highly conserved C-terminal STAS (Sulphate Transporter and AntiSigma factor antagonist) domain. The C-terminal STAS domain is the target of the serine/threonine-specific kinase RsbT (see below).

• Modification: RsbRA: Thr-171 and Thr-205
