| Accepted name: |
protoporphyrin ferrochelatase |
| Reaction: |
protoheme + 2 H+ = protoporphyrin + Fe2+ |
| Other name(s): |
ferro-protoporphyrin chelatase; iron chelatase (ambiguous); heme synthetase (ambiguous); heme synthase (ambiguous); protoheme ferro-lyase; ferrochelatase (ambiguous) |
| Systematic name: |
protoheme ferro-lyase (protoporphyrin-forming) |
| Comments: |
The enzyme catalyses the terminal step in the heme biosynthesis pathways of eukaryotes and Gram-negative bacteria. |
