allysine
6-oxonorleucine; 2-aminoadipaldehydic acid; an α-amino acid not normally found in proteins, but enzymically formed from lysine in situ as an intermediate in the creation of covalent cross-links between adjacent polypeptide strands during the maturation of certain connective-tissue proteins (e.g., collagen, elastin). The enzyme lysyl oxidase oxidizes the terminal amino-methylene groups of residues of either lysine or 5-hydroxylysine to aldehyde groups, forming residues of allysine or hydroxyallysine respectively. See also desmosine, isodesmosine, lathyrism, noncoded amino acid, syndesine.

Allysine is a derivative of lysine, used in the production of elastin and collagen. It is produced by the actions of the enzyme lysyl oxidase in the extracellular matrix and is essential in the crosslink formation that stabilizes collagen and elastin.
