Advances in Nutrition, 2010 Vitamin B-12 is a cofactor for 2 enzymes. In the cytoplasm, methionine synthase requires vitamin B-12 in the form of methylcobalamin and catalyzes the conversion of homocysteine to methionine by transfer of a methyl group from methyltetrahydrofolate. This enzyme links the methylation pathway through synthesis of the methyl donor S-adenosyl methionine ...
