Function
function
Catalyzes the 6-electron oxidation of protoporphyrinogen IX to form protoporphyrin IX; under anaerobic conditions uses menaquinone as an electron acceptor, under aerobic conditions uses ubiquinone as an electron acceptor.
Catalytic activity
- protoporphyrinogen IX + 3 a menaquinone = protoporphyrin IX + 3 a menaquinol
- protoporphyrinogen IX + 3 a ubiquinone = protoporphyrin IX + 3 a ubiquinol
Cofactor
Note: Binds 1 FMN non-covalently per subunit.
Pathway
Porphyrin-containing compound metabolism; protoporphyrin-IX biosynthesis; protoporphyrin-IX from protoporphyrinogen-IX: step 1/1.
