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: 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 protein (By 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.
  • SIMILARITY: Contains 1 Rieske domain.
