Lanthionine is a nonproteinogenic amino acid with the chemical formula (HOOC-CH(NH₂)-CH₂-S-CH₂-CH(NH₂)-COOH). It is typically formed by a cysteine residue and a dehydrated serine residue. Despite its name, lanthionine does not contain the element lanthanum.

In 1941, lanthionine was first isolated by treating wool with sodium carbonate. It was found to be a sulfur-containing amino acid; accordingly it was given the name lanthionine [wool (Latin: Lana), sulfur (Greek: theîon)].^[1] Lanthionine was first synthesized by alkylation of cysteine with β-chloroalanine.^[2] Lanthionines are found widely in nature. They have been isolated from human hair, lactalbumin, and feathers. Lanthionines have also been found in bacterial cell walls and are the components of a group of gene-encoded peptide antibiotics called lantibiotics, which includes nisin (a food preservative), subtilin, epidermin (effective against Staphylococcus and Streptococcus), and ancovenin (an enzyme inhibitor).^[3]^[4]

A variety of syntheses of lanthionine have been published including sulfur extrusion from cystine,^[5] ring opening of serine β-lactone,^[4] and hetero-conjugate addition of cysteine to dehydroalanine.^[6] The sulfur extrusion method is, however, the only pathway for lanthionine that has been employed in the total synthesis of a lantibiotic.

Biosynthesis of the lanthionine bridge in peptidic natural products can be accomplished through a number of different pathways. For example, the lanthionine bridges in the antibiotic nisin are the result of a dedicated dehydratase (NisB) and a dedicated cyclase (NisC).^[7]^[8]
