CC   -!- FUNCTION: Involved in the heme biosynthesis. Catalyzes the aerobic
CC       oxidative decarboxylation of propionate groups of rings A and B of
CC       coproporphyrinogen-III to yield the vinyl groups in protoporphyrinogen-
CC       IX. {ECO:0000255|HAMAP-Rule:MF_00333}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=coproporphyrinogen III + 2 H(+) + O2 = 2 CO2 + 2 H2O +
CC         protoporphyrinogen IX; Xref=Rhea:RHEA:18257, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:16526,
CC         ChEBI:CHEBI:57307, ChEBI:CHEBI:57309; EC=1.3.3.3;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00333};
CC   -!- COFACTOR:
CC       Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00333};
CC   -!- PATHWAY: Porphyrin-containing compound metabolism; protoporphyrin-IX
CC       biosynthesis; protoporphyrinogen-IX from coproporphyrinogen-III (O2
CC       route): step 1/1. {ECO:0000255|HAMAP-Rule:MF_00333}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00333}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00333}.
CC   -!- SIMILARITY: Belongs to the aerobic coproporphyrinogen-III oxidase
CC       family. {ECO:0000255|HAMAP-Rule:MF_00333}.
