Hydroxylysine (Hyl) is an amino acid with the molecular formula C₆H₁₄N₂O₃. It was first discovered in 1921 by Donald Van Slyke as the 5-hydroxylysine form.^[1] It arises from a post-translational hydroxy modification of lysine. It is most widely known as a component of collagen.^[2]

It is biosynthesized from lysine via oxidation by lysyl hydroxylase enzymes. The most common form is the (5R) stereoisomer found in collagen. However, the enzyme JMJD6 has recently been shown to be a lysyl hydroxylase which modifies an RNA splicing factor producing the (5S) stereoisomer. Additionally, in E. coli, there has been at least one lysine N-hydroxylase enzyme identified, named IucD.^[3]
