ENZYME: 7.1.1.8


ID   7.1.1.8
DE   Quinol--cytochrome-c reductase.
AN   Complex III (mitochondrial electron transport).
AN   Cytochrome bc1 complex.
AN   Ubiquinol--cytochrome-c reductase.
AN   Ubiquinone--cytochrome-c oxidoreductase.
CA   Quinol + 2 ferricytochrome c(Side 2) = quinone + 2 ferrocytochrome c(Side
CA   2) + 2 H(+)(Side 2).
CC   -!- The enzyme, often referred to as the cytochrome bc1 complex or
CC       complex III, is the third complex in the electron transport chain.
CC   -!- It is present in the mitochondria of all aerobic eukaryotes and in
CC       the inner membranes of most bacteria.
CC   -!- The mammalian enzyme contains cytochromes b-562, b-566 and c(1),
CC       and a 2-iron ferredoxin.
CC   -!- Depending on the organism and physiological conditions, the enzyme
CC       extrudes either two or four protons from the cytoplasmic to the non-
CC       cytoplasmic compartment (cf. EC 1.6.99.3).
CC   -!- Formerly EC 1.10.2.2.
