  • Cytochrome-c Oxidase
  • Cytochrome-c Oxidase (Complex IV)
  • Cytochrome Oxidase
  • Ferrocytochrome c Oxygen Oxidoreductase
  • Oxidase, Cytochrome

Note

  • spell in titles & translations with lowercase c: cytochrome-c oxidase

Scope note

  • A multisubunit enzyme complex containing CYTOCHROME A GROUP; CYTOCHROME A3; two copper atoms; and 13 different protein subunits. It is the terminal oxidase complex of the RESPIRATORY CHAIN and collects electrons that are transferred from the reduced CYTOCHROME C GROUP and donates them to molecular OXYGEN, which is then reduced to water. The redox reaction is simultaneously coupled to the transport of PROTONS across the inner mitochondrial membrane.

History note

  • 2004(1963); for SIGNAL PEPTIDE P25-SUBUNIT IV CYTOCHROME OXIDASE use CYTOCHROME C OXIDASE (NM) 1988-2001; for CYTOCHROME OXIDASE SUBUNIT III use CYTOCHROME C OXIDASE (NM) 1998-2001
