Comments
  • FUNCTION: Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.
  • CATALYTIC ACTIVITY: QH2 + 2 ferricytochrome c = Q + 2 ferrocytochrome c + 2 H+.
  • COFACTOR: Binds 1 2Fe-2S cluster per subunit (By similarity).
  • SUBUNIT: The bc1 complex contains 10 subunits; 3 respiratory subunits, 2 core proteins and 5 low-molecular weight proteins.
  • SUBCELLULAR LOCATION: Mitochondrion inner membrane.
  • MISCELLANEOUS: The Rieske protein is a high potential 2Fe-2S protein.
  • SIMILARITY: Contains 1 Rieske domain.
