Protein phosphatase 2C 57

UniProtKB accession:  P49599

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Protein phosphatase specifically required for efficient dephosphorylation of the light-harvesting complex II outer antennae (LCHII) and transition from state 2 to state 1 (PubMed:20176943, PubMed:20126264). State transition plays a central role in response to environmental changes and allows to adjust to changing light conditions via the redistribution of light excitation energy between photosystem II (PSII) and photosystem I (PSI) in a short time by relocating LHCII proteins (Probable). Mainly responsible for the dephosphorylation of Lhcb1 and Lhcb2 but not of the photosystem II core proteins (PubMed:20176943).
