As the monosulfide analog of cystine, lanthionine is composed of two alanine residues that are crosslinked on their β-carbon atoms by a thioether linkage. Despite its name, lanthionine does not contain the element lanthanum. ==Background== In 1941, lanthionine was first isolated from the treatment of wool with sodium carbonate〔Horn, M. J.; Jones, D. B.; Ringel, S. J. (1941) Isolation of a New Sulfur-Containing Amino Acid (Lanthionine) from Sodium Carbonate-Treated Wool. ''Journal of Biological Chemistry'', ''138'', 141-149.〕 and was first synthesized from cysteine and β-chloroalanine.〔Brown, G. B.; du Vigneaud, V. (1941) The Stereoisomeric Forms of Lanthionine. ''Journal of Biological Chemistry'', ''140'', 767-771.〕 Lanthionines are found widely in nature and 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).〔Paul, M.; van der Donk, W.
