  • GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
  • GO:0051537 Binding to a 2 iron, 2 sulfur (2Fe-2S) cluster; this cluster consists of two iron atoms, with two inorganic sulfur atoms found between the irons and acting as bridging ligands.
  • GO:0046872 Binding to a metal ion.
  • GO:0016491 Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
  • GO:0008121 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: a quinol + 2 Fe(III)-cytochrome c = a quinone + 2 Fe(II)-cytochrome c + 2 H+(out).
  • GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
