Function

PPP5_ARATH Isoform 2 dephosphorylates phosphorylated phytochromes, with a preference toward Pfr forms, and enhances phytochrome-mediated photoresponses, probably by enhancing their stability and their binding affinity for light signal transducers such as NDPK2. Can use para-nitrophenylphosphate (pNPP) as substrate.[1]
