There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Quinol--cytochrome-c reductase. [EC: 1.10.2.2]
Quinol + 2 ferricytochrome c = quinone + 2 ferrocytochrome c + 2 H(+).
  • The enzyme, often referred to as the cytochrome bc1 complex or complex III, is the third complex in the electron transport chain.
  • It is present in the mitochondria of all aerobic eukaryotes and in the inner membranes of most bacteria.
  • The mammalian enzyme contains cytochromes b-562, b-566 and C(1), and a 2-iron ferredoxin.
  • Depending on the organism and physiological conditions, the enzyme extrudes either two or four protons from the cytoplasmic to the non- cytoplasmic compartment (cf. EC 1.6.99.3).
