CC -!- FUNCTION: Multifunctional enzyme that catalyzes the SAM-dependent CC methylations of uroporphyrinogen III at position C-2 and C-7 to CC form precorrin-2 via precorrin-1. Then it catalyzes the NAD- CC dependent ring dehydrogenation of precorrin-2 to yield CC sirohydrochlorin. Finally, it catalyzes the ferrochelation of CC sirohydrochlorin to yield siroheme. {ECO:0000256|HAMAP- CC Rule:MF_01646, ECO:0000256|SAAS:SAAS00971394}.
