CC -!- FUNCTION: Component of the cytochrome b6-f complex, which mediates
CC electron transfer between photosystem II (PSII) and photosystem I
CC (PSI), cyclic electron flow around PSI, and state transitions.
CC {ECO:0000256|HAMAP-Rule:MF_01335}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a plastoquinol + 2 H(+)(in) + 2 oxidized [plastocyanin] = a
CC plastoquinone + 4 H(+)(out) + 2 reduced [plastocyanin];
CC Xref=Rhea:RHEA:22148, Rhea:RHEA-COMP:9561, Rhea:RHEA-COMP:9562,
CC Rhea:RHEA-COMP:10039, Rhea:RHEA-COMP:10040, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:17757, ChEBI:CHEBI:29036, ChEBI:CHEBI:49552,
CC ChEBI:CHEBI:62192; EC=7.1.1.6;
CC Evidence={ECO:0000256|ARBA:ARBA00000603, ECO:0000256|HAMAP-
CC Rule:MF_01335};
CC -!- COFACTOR:
CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01335};
CC Note=Binds 1 [2Fe-2S] cluster per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_01335};
CC -!- SUBUNIT: The 4 large subunits of the cytochrome b6-f complex are
CC cytochrome b6, subunit IV (17 kDa polypeptide, PetD), cytochrome f and
CC the Rieske protein, while the 4 small subunits are PetG, PetL, PetM and
CC PetN. The complex functions as a dimer. {ECO:0000256|HAMAP-
CC Rule:MF_01335}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000256|HAMAP-
CC Rule:MF_01335}; Single-pass membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_01335}. Note=The transmembrane helix obliquely spans the
CC membrane in one monomer, and its extrinsic C-terminal domain is part of
CC the other monomer. {ECO:0000256|HAMAP-Rule:MF_01335}.
CC -!- MISCELLANEOUS: The Rieske iron-sulfur protein is a high potential 2Fe-
CC 2S protein. {ECO:0000256|HAMAP-Rule:MF_01335}.
CC -!- SIMILARITY: Belongs to the Rieske iron-sulfur protein family.
CC {ECO:0000256|HAMAP-Rule:MF_01335}.
