Photosystem II extrinsic protein O

UniProtKB accession:  D0VWR2

Grouped By:  Matching UniProtKB accession

UniProtKB description:  One of the extrinsic, lumenal subunits of photosystem II (PSII), which stabilize and protect the oxygen-evolving complex. PSII is a light-driven water plastoquinone oxidoreductase, using light energy to abstract electrons from H(2)O, generating a proton gradient subsequently used for ATP formation (PubMed:19433803, PubMed:21499260, PubMed:23426624). Required for dimerization of PSII and for binding of PsbQ to PSII (By similarity).
