'''Methionine synthase''' (MS; EC: 2.1.1.13) is the enzyme in [[one-carbon metabolism]] linking the folate cycle to the methionine cycle. MS catalyzes the transfer of a methyl group from 5-methyltetrahydrofolate (5- me THF) to homocysteine, resulting in the formation of methionine and tetrahydrofolate (THF). Methionine is an essential amino acid required by our bodies for healthy cell and tissue growth. It is essential as it is not naturally derived in our bodies. As it is used as a methyl donor in the form of S-adenosylmethionine, the resulting homocysteine is recyled to form methionine again. | '''Methionine synthase''' (MS; EC: 2.1.1.13) or '''5-methyltetrahydrofolate S-homocysteine methyltransferase''' is the enzyme in [[one-carbon metabolism]] linking the folate cycle to the methionine cycle.
