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:0000255|HAMAP-Rule:MF_01442}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Fe-coproporphyrin III + 2 H(+) + 2 H2O2 = 2 CO2 + 4 H2O + heme
