- 2 menahinol + O2 2 menahinon + 2H2O
Citohrom aa3-600 je jedan od glavnih respiratornih oksidaza kod Bacillus subtilis. On je takođe član hem-bakar superfamilije kiseoničnih reduktaza, i blisko je homologan sa citohrom bo3 ubihinol oksidazom iz Escherichia coli, ali koristi menahinol umesto ubihinola kao supstrat.
