FIGURE 1. Reactions catalyzed by copper amine oxidases are biogenesis (a) and catalysis (b). a, the protein derived cofactor, TPQ, is the product of biogenesis and generates the mature enzyme. P represents the rest of the polypeptide chain. b, catalysis is divided into two half-reactions, reductive and oxidative. R represents the moiety of the substrate amine, which varies from a hydrogen atom to a polypeptide.
