Protein

Siroheme synthase

Gene

cysG

Organism
Hahella chejuensis (strain KCTC 2396)
Status
Reviewed - Annotation score: 5 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 annotation

Catalytic activityi

S-adenosyl-L-methionine + uroporphyrinogen III = S-adenosyl-L-homocysteine + precorrin-1.UniRule annotation
S-adenosyl-L-methionine + precorrin-1 = S-adenosyl-L-homocysteine + precorrin-2.UniRule annotation
Precorrin-2 + NAD+ = sirohydrochlorin + NADH.UniRule annotation
Siroheme + 2 H+ = sirohydrochlorin + Fe2+.UniRule annotation
