Description | Methionine (abbreviated as Met or M) is an alpha-amino acid. The L-isomer is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. It is classified as a nonpolar amino acid, because of the hydrophobic nature of the thioether-alkyl side chain. Together with cysteine, methionine is one of two sulfur-containing proteinogenic amino acids. Its derivative S-adenosyl methionine (SAM) serves as a methyl donor. Methionine is an intermediate in the biosynthesis of cysteine, carnitine, taurine, lecithin, phosphatidylcholine, and other phospholipids. Methionine is synthesized via a pathway that uses both aspartic acid and cysteine. First, aspartic acid is converted via β-aspartyl-semialdehyde into homoserine, introducing the pair of contiguous methylene groups. Homoserine converts to O-succinyl homoserine, which then reacts with cysteine to produce cystathionine, which is cleaved to yield homocysteine. Subsequent methylation of the thiol group by folates affords methionine. The principal fates methionine are incorporation into polypeptide chains, and use in the production of alpha-ketobutyrate and cysteine via SAM (S-adenosylmethionine). The transulfuration reactions that produce cysteine from homocysteine and serine also produce alpha-ketobutyrate, the latter being converted first to propionyl-CoA and then via a 3-step process to succinyl-CoA. |
