CC -!- FUNCTION: Catalyzes the 6-electron oxidation of protoporphyrinogen IX
CC to form protoporphyrin IX; under anaerobic conditions uses menaquinone
CC as an electron acceptor, under aerobic conditions uses ubiquinone as an
CC electron acceptor. {ECO:0000256|HAMAP-Rule:MF_00853}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3 a menaquinone + protoporphyrinogen IX = 3 a menaquinol +
CC protoporphyrin IX; Xref=Rhea:RHEA:27409, Rhea:RHEA-COMP:9537,

CC Note=Binds 1 FMN non-covalently per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_00853};
CC -!- PATHWAY: Porphyrin-containing compound metabolism; protoporphyrin-IX
CC biosynthesis; protoporphyrin-IX from protoporphyrinogen-IX: step 1/1.
CC {ECO:0000256|HAMAP-Rule:MF_00853}.
