1 interaction related to methionine synthase
Vitamin B12 and folate are interdependent coenzymes in the methionine cycle: methylfolate donates a methyl group to homocysteine while B12 (methylcobalamin) is the required cofactor for methionine synthase, the enzyme catalyzing the reaction. Adequate intake of both is needed to lower homocysteine, support DNA synthesis, and prevent the neurologic damage that high-dose folate alone can mask.
