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 By similarity.

Catalytic activity

Plastoquinol-1 + 2 oxidized plastocyanin = plastoquinone + 2 reduced plastocyanin.

Cofactor

Binds 1 2Fe-2S cluster per subunit By similarity.

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 By similarity.

Subcellular location

Cellular thylakoid membrane; Single-pass membrane proteinBy similarity. Note= The transmembrane helix obliquely spans the membrane in one monomer, and its extrinsic C-terminal domain is part of the other monomer By similarity.

Miscellaneous

The Rieske iron-sulfur protein is a high potential 2Fe-2S protein.

Sequence similarities

Contains 1 Rieske domain.
