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}.
