The protein

Catalyzed reaction/ biological activity

• dephosphorylation of RsbV in response to red light, this results in SigB activation PubMed
• H₂O + O-phospho-L(or D)-serine --> L(or D)-serine + phosphate (according to UniProt)

Domains

• N-terminal PAS domain, central coiled-coil domain, C-terminal PP2C phosphatase domain

Effectors of protein activity

• activity is stimulated upon interaction of the RsbP oligomer with RsbQ PubMed
