CC -!- FUNCTION: Component of the cytochrome b6-f complex, which mediates
CC electron transfer between photosystem II (PSII) and photosystem I
CC (PSI), cyclic electron flow around PSI, and state transitions.
CC {ECO:0000255|HAMAP-Rule:MF_01344}.
CC -!- SUBUNIT: The 4 large subunits of the cytochrome b6-f complex are
CC cytochrome b6, subunit IV (17 kDa polypeptide, petD), cytochrome f and
CC the Rieske protein, while the 4 small subunits are petG, petL, petM and
CC petN. The complex functions as a dimer (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000255|HAMAP-Rule:MF_01344}; Multi-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_01344}.
CC -!- SIMILARITY: Belongs to the cytochrome b family. PetD subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01344}.
