Protein name

RecName: Full=Cytochrome b6-f complex subunit 8; AltName: Full=Cytochrome b6-f complex subunit VIII; AltName: Full=Cytochrome b6-f complex subunit petN;

Gene name

petN

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).

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: Plastid, chloroplast thylakoid membrane; Single-pass membrane protein (By similarity).

SUBCELLULAR LOCATION: Cell inner membrane; Single-pass membrane protein (By similarity).

SUBCELLULAR LOCATION: Cellular thylakoid membrane; Single-pass membrane protein (By similarity).

SIMILARITY: Belongs to the petN family.
