CC -!- FUNCTION: Involved in coproporphyrin-dependent heme b biosynthesis.
CC Catalyzes the decarboxylation of Fe-coproporphyrin III (coproheme) to
CC heme b (protoheme IX), the last step of the pathway. The reaction
CC occurs in a stepwise manner with a three-propionate intermediate.
CC {ECO:0000256|HAMAP-Rule:MF_02244}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Fe-coproporphyrin III + 2 H(+) + 2 H2O2 = 2 CO2 + 4 H2O + heme
CC b; Xref=Rhea:RHEA:56516, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC Rule:MF_02244};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Fe-coproporphyrin III + H(+) + H2O2 = CO2 + 2 H2O +
CC harderoheme III; Xref=Rhea:RHEA:57940, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16240, ChEBI:CHEBI:16526,

CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + H2O2 + harderoheme III = CO2 + 2 H2O + heme b;
CC Xref=Rhea:RHEA:57944, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC -!- COFACTOR:
CC Name=Fe-coproporphyrin III; Xref=ChEBI:CHEBI:68438;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02244};
CC Note=Fe-coproporphyrin III acts as both substrate and redox cofactor.
CC {ECO:0000256|HAMAP-Rule:MF_02244};
CC -!- PATHWAY: Porphyrin-containing compound metabolism; protoheme
CC biosynthesis. {ECO:0000256|HAMAP-Rule:MF_02244}.
CC -!- SIMILARITY: Belongs to the ChdC family. Type 2 subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_02244}.
