General annotation (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. HAMAP-Rule MF_01344

Subunit structure

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.

Subcellular location

Cellular thylakoid membrane; Multi-pass membrane protein HAMAP-Rule MF_01344.

Sequence similarities

Belongs to the cytochrome b family. PetD subfamily.
