Protein

Siroheme synthase

Gene

cysG

Organism
Acinetobacter calcoaceticus (strain PHEA-2)
Status
Unreviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

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.UniRule annotationSAAS annotation

Catalytic activityi

Precorrin-2 + NAD+ = sirohydrochlorin + NADH.UniRule annotationSAAS annotation
