Precorrin-2 C20-methyltransferase
Template:Infobox enzyme In enzymology, a precorrin-2 C20-methyltransferase (EC 2.1.1.130) is an enzyme that catalyzes the chemical reaction
- S-adenosyl-L-methionine + precorrin-2 S-adenosyl-L-homocysteine + precorrin-3A
The two substrates of this enzyme are S-adenosyl methionine and precorrin 2 and its two products are S-adenosylhomocysteine and precorrin 3A.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:precorrin-4 C20-methyltransferase and another names in common use is CobI. The enzyme is part of the biosynthetic pathway to cobalamin (vitamin B12) in aerobic bacteria.
