| cobA | cysG | Atu2794 | Atu1454 | uroporphyrin-III C-methyltransferase; Belongs to the precorrin methyltransferase family. | Siroheme synthase; Multifunctional enzyme that catalyzes the SAM-dependent methylations of uroporphyrinogen III at position C-2 and C-7 to form precorrin-2 via precorrin-1. Then it catalyzes the NAD-dependent ring dehydrogenation of precorrin-2 to yield sirohydrochlorin. Finally, it catalyzes the ferrochelation of sirohydrochlorin to yield siroheme. Belongs to the precorrin methyltransferase family. In the N-terminal section; belongs to the precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase family. | 0.951 |
