Methionine synthase also known as MS, MeSe, MTR is responsible for the regeneration of methionine from homocysteine. In humans it is encoded by the MTR gene (5-methyltetrahydrofolate-homocysteine methyltransferase). Methionine synthase forms part of the S-adenosylmethionine … Meer weergeven Methionine synthase catalyzes the final step in the regeneration of methionine (Met) from homocysteine (Hcy). Both the cobalamin-dependent and cobalamin-independent forms of the enzyme carry out the … Meer weergeven Mutations in the MTR gene have been identified as the underlying cause of methylcobalamin deficiency complementation group G, or methylcobalamin deficiency cblG-type.
