Cytochrome bc1 complex Rieske iron-sulfur subunit

UniProtKB accession:  A0R051

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Iron-sulfur subunit of the cytochrome bc1 complex, an essential component of the respiratory electron transport chain required for ATP synthesis. The bc1 complex catalyzes the oxidation of menaquinol and the reduction of cytochrome c in the respiratory chain. The bc1 complex operates through a Q-cycle mechanism that couples electron transfer to generation of the proton gradient that drives ATP synthesis.
