| EC Number | 1.3.98.5 |
| Enzyme Function | FUNCTION: Involved in coproporphyrin-dependent heme b biosynthesis. Catalyzes the decarboxylation of Fe-coproporphyrin III (coproheme) to heme b (protoheme IX), the last step of the pathway. The reaction occurs in a stepwise manner with a three-propionate intermediate. {ECO:0000255|HAMAP-Rule:MF_01442}. |
