|
| 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.
