FUNCTIONComponent of the cytochrome b6-f complex, which mediates electron transfer between photosystem II (PSII) and photosystem I (PSI), cyclic electron flow around PSI, and state transitions.
SUBUNITThe 4 large subunits of the cytochrome b6-f complex are cytochrome b6, subunit IV (17 kDa polypeptide, PetD), cytochrome f and the Rieske protein, while the 4 small subunits are PetG, PetL, PetM and PetN. The complex functions as a dimer.

else case <OC:Gloeobacter>
SUBCELLULAR LOCATIONCell inner membrane; Multi-pass membrane protein.
SUBCELLULAR LOCATIONCellular thylakoid membrane; Multi-pass membrane protein.
end case
SIMILARITYBelongs to the cytochrome b family. PetD subfamily.

Comments In barley and maize a longer, unspliced form of the gene is transcribed. It can also be predicted for at least rice and lettuce, and probably other Magnoliophytes. It is not known is this RNA is translated.
