CC -!- FUNCTION: Multifunctional enzyme that catalyzes the SAM-dependent CC methylations of uroporphyrinogen III at position C-2 and C-7 to form CC precorrin-2 via precorrin-1. Then it catalyzes the NAD-dependent ring CC dehydrogenation of precorrin-2 to yield sirohydrochlorin. Finally, it CC catalyzes the ferrochelation of sirohydrochlorin to yield siroheme.
