Precorrin-4 C11-methyltransferase
Template:Infobox enzyme In enzymology, a precorrin-4 C11-methyltransferase (EC 2.1.1.133) is an enzyme that catalyzes the chemical reaction
- S-adenosyl-L-methionine + precorrin-4 S-adenosyl-L-homocysteine + precorrin-5
The two substrates of this enzyme are S-adenosyl methionine and precorrin 4; its two products are S-adenosylhomocysteine and precorrin 5.
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 C11 methyltransferase. Other names in common use include precorrin-3 methylase, and CobM. It is part of the biosynthetic pathway to cobalamin (vitamin B12) in aerobic bacteria.
