FunFam 24206: Ubiquinol oxidase, subunit II

There are 2 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
Cytochrome-c oxidase. [EC: 1.9.3.1]
4 ferrocytochrome c + O(2) + 4 H(+) = 4 ferricytochrome c + 2 H(2)O.
  • The reduction of O(2) to water is accompanied by the extrusion of four protons from the intramitochondrial compartment.
  • Several bacteria appear to contain analogous oxidases.

Menaquinol oxidase (H(+)-transporting). [EC: 1.10.3.12]
2 menaquinol + O(2) = 2 menaquinone + 2 H(2)O.
  • Cytochrome aa3-600, one of the principal respiratory oxidases from Bacillus subtilis, is a member of the heme-copper superfamily of oxygen reductases, and is a close homolog of the cytochrome bo3 ubiquinol oxidase from Escherichia coli, but uses menaquinol instead of ubiquinol as a substrate.
  • The enzyme also pumps protons across the membrane bilayer, generating a proton motive force.
