ENZYME entry: EC 7.1.1.5

Accepted Name
menaquinol oxidase (H(+)-transporting)
Alternative Name(s)
cytochrome aa3-600 oxidase
cytochrome bd oxidase
Reaction catalysed
2 a menaquinol + n H(+)(in) + O2 <=> 2 a menaquinone + n H(+)(out) + 2 H2O(in)
Comment(s)
  • 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.
  • Formerly EC 1.10.3.12.
