General annotation (Comments)

Function

Multifunctional enzyme that catalyzes the SAM-dependent methylation of uroporphyrinogen III at position C-2 and C-7 to form precorrin-2 and then position C-12 or C-18 to form trimethylpyrrocorphin 2. It also catalyzes the conversion of precorrin-2 into siroheme. This reaction consists of the NAD-dependent oxidation of precorrin-2 into sirohydrochlorin and its subsequent ferrochelation into siroheme By similarity. HAMAP-Rule MF_01646

Catalytic activity

S-adenosyl-L-methionine + uroporphyrinogen III = S-adenosyl-L-homocysteine + precorrin-1. HAMAP-Rule MF_01646

S-adenosyl-L-methionine + precorrin-1 = S-adenosyl-L-homocysteine + precorrin-2. HAMAP-Rule MF_01646

Precorrin-2 + NAD+ = sirohydrochlorin + NADH. HAMAP-Rule MF_01646

Siroheme + 2 H+ = sirohydrochlorin + Fe2+. HAMAP-Rule MF_01646

Pathway

Cofactor biosynthesis; adenosylcobalamin biosynthesis; precorrin-2 from uroporphyrinogen III: step 1/1. HAMAP-Rule MF_01646

Cofactor biosynthesis; adenosylcobalamin biosynthesis; sirohydrochlorin from precorrin-2: step 1/1.
