CC -!- FUNCTION: One of the components of the core complex of photosystem II
CC (PSII), required for its stability and/or assembly. PSII is a light-
CC driven water:plastoquinone oxidoreductase that uses light energy to
CC abstract electrons from H(2)O, generating O(2) and a proton gradient
CC subsequently used for ATP formation. It consists of a core antenna
CC complex that captures photons, and an electron transfer chain that
CC converts photonic excitation into a charge separation.
CC {ECO:0000255|HAMAP-Rule:MF_00752}.
CC -!- SUBUNIT: PSII is composed of 1 copy each of membrane proteins PsbA,
CC PsbB, PsbC, PsbD, numerous small proteins, at least 3 peripheral
CC proteins of the oxygen-evolving complex and a large number of
CC cofactors. It forms dimeric complexes (By similarity). Detected in both
CC etioplasts and green leaves; PSII is only assembled in green leaves
CC (PubMed:19137553). {ECO:0000255|HAMAP-Rule:MF_00752,
CC ECO:0000269|PubMed:19137553}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000255|HAMAP-Rule:MF_00752, ECO:0000305|PubMed:19137553}; Single-
CC pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00752,
CC ECO:0000305|PubMed:19137553}.
CC -!- PTM: Phosphorylation is a light-dependent reaction catalyzed by a
CC membrane-bound kinase; phosphorylation occurs on Thr residue(s) in the
CC N-terminus of the protein. {ECO:0000255|HAMAP-Rule:MF_00752}.
CC -!- SIMILARITY: Belongs to the PsbH family. {ECO:0000255|HAMAP-
CC Rule:MF_00752}.
