CC   -!- FUNCTION: Multifunctional enzyme that catalyze the SAM-dependent
CC       methylation of uroporphyrinogen III at position C-2 and C-7 to
CC       form precorrin-2 and then position C-12 or C-18 to form
CC       trimethylpyrrocorphin 2. It also catalyzes the conversion of
CC       precorrin-2 into siroheme. This reaction consist of the NAD-
CC       dependent oxidation of precorrin-2 into sirohydrochlorin and its
CC       subsequent ferrochelation into siroheme (By similarity).
CC   -!- CATALYTIC ACTIVITY: S-adenosyl-L-methionine + uroporphyrinogen III
CC       = S-adenosyl-L-homocysteine + precorrin-1.
CC   -!- CATALYTIC ACTIVITY: S-adenosyl-L-methionine + precorrin-1 = S-
CC       adenosyl-L-homocysteine + precorrin-2.
CC   -!- CATALYTIC ACTIVITY: Precorrin-2 + NAD(+) = sirohydrochlorin +
CC       NADH.
CC   -!- CATALYTIC ACTIVITY: Siroheme + 2 H(+) = sirohydrochlorin + Fe(2+).
CC   -!- PATHWAY: Cofactor biosynthesis; adenosylcobalamin biosynthesis;
CC       precorrin-2 from uroporphyrinogen III: step 1/1.
CC   -!- PATHWAY: Cofactor biosynthesis; adenosylcobalamin biosynthesis;
CC       sirohydrochlorin from precorrin-2: step 1/1.
CC   -!- PATHWAY: Porphyrin metabolism; siroheme biosynthesis; precorrin-2
CC       from uroporphyrinogen III: step 1/1.
CC   -!- PATHWAY: Porphyrin metabolism; siroheme biosynthesis; siroheme
CC       from sirohydrochlorin: step 1/1.
CC   -!- PATHWAY: Porphyrin metabolism; siroheme biosynthesis;
CC       sirohydrochlorin from precorrin-2: step 1/1.
CC   -!- SIMILARITY: Belongs to the precorrin methyltransferase family.
