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_00396}.
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. {ECO:0000255|HAMAP-
CC       Rule:MF_00396}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00396}; Single-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00396}.
CC   -!- SIMILARITY: Belongs to the PetM family. {ECO:0000255|HAMAP-
CC       Rule:MF_00396}.
