Comments [?]

Function Component 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.
Subunit The 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.
case <OG:Chloroplast>

else case <OC:Gloeobacter>
Subcellular location Cell inner membrane; Single-pass membrane protein.
else
Subcellular location Cellular thylakoid membrane; Single-pass membrane protein.
end case
Similarity Belongs to the PetN family.
