ENZYME entry: EC 1.4.3.13

Accepted Name
Protein-lysine 6-oxidase.
Alternative Name(s)
Lysyl oxidase.
Reaction catalysed
[Protein]-L-lysine + O(2) + H(2)O <=> [protein]-(S)-2-amino-6-oxohexanoate + NH(3) + H(2)O(2)
Comment(s)
  • Also acts on protein 5-hydroxylysine.
  • Catalyzes the final known enzymic step required for collagen and elastin cross-linking in the biosynthesis of normal mature extracellular matrices.
  • These reactions play an important role for the development, elasticity and extensibility of connective tissue.
  • Also active on free amines, such as cadaverine or benzylamine.
