Methionine synthase

Methionine synthase also known as MS, MeSe, MetH 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 (SAMe) biosynthesis and regeneration cycle. In animals this enzyme requires Vitamin B12 (cobalamin) as a cofactor, whereas the form found in plants is cobalamin-independent. Microorganisms express both cobalamin-dependent and cobalamin-independent forms.
