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. |
Cofactor | heme Note: Binds 1 heme group covalently. |
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>
Subcellular location | Plastid, chloroplast thylakoid membrane; Single-pass membrane protein. |
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 cytochrome f family. |
