General Information | Comment | Organism |
---|---|---|
evolution | the cytochrome ba3 oxidase belongs to the family B of the heme-copper containing terminal oxidases, heme-copper oxidases use either c-type cytochromes or quinols as electron donors | Aquifex aeolicus |
additional information | the enzyme can be reduced by ubiquinol, but it alone can also be reduced by decylubiquinol and N,N,N',N'-tetramethyl-4-phenylenediamine/ascorbate in the presence of cyanide | Aquifex aeolicus |
