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. {ECO:0000255|HAMAP-
CC Rule:MF_00752}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_00752}; Single-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_00752}.
CC -!- SIMILARITY: Belongs to the PsbH family. {ECO:0000255|HAMAP-
CC Rule:MF_00752}.
