A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 7.1.1.4

Accepted Name
Caldariellaquinol oxidase (H(+)-transporting).
Alternative Name(s)
Aa(3) quinol oxidase.
Aa(3)-type quinol oxidase.
Cytochrome aa3.
Cytochrome aa3-type oxidase.
Terminal quinol oxidase.
Reaction catalysed
2 caldariellaquinol + O(2) + n H(+)(Side 1) <=> 2 caldariellaquinone + 2 H(2)O + n H(+)(Side 2)
Cofactor(s)
Cu cation.
Comment(s)
  • The enzyme from thermophilic archaea is part of the terminal oxidase and catalyzes the reduction of O(2) to water, accompanied by the extrusion of protons across the cytoplasmic membrane.
  • Formerly EC 1.10.3.13.
