CC -!- FUNCTION: This b-type cytochrome is tightly associated with the
CC reaction center of photosystem II (PSII). PSII is a light-driven
CC water:plastoquinone oxidoreductase that uses light energy to abstract
CC 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:0000256|RuleBase:RU004529}.
CC -!- SUBUNIT: Heterodimer of an alpha subunit and a beta subunit.
CC {ECO:0000256|RuleBase:RU004529}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004167}; Single-
CC pass membrane protein {ECO:0000256|ARBA:ARBA00004167}. Plastid,
CC chloroplast thylakoid membrane {ECO:0000256|RuleBase:RU004529}; Single-
CC pass membrane protein {ECO:0000256|RuleBase:RU004529}.
CC -!- SIMILARITY: Belongs to the PsbE/PsbF family.
CC {ECO:0000256|RuleBase:RU004529}.
