Comments [?]

FUNCTIONCatalyzes 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 Reaction=3 a quinone + protoporphyrinogen IX = 3 a quinol + protoporphyrin IX; Xref=Rhea:RHEA:65032, ChEBI:CHEBI:24646, ChEBI:CHEBI:57306, ChEBI:CHEBI:57307, ChEBI:CHEBI:132124; EC=;
