In enzymology, a L-pipecolate oxidase () is an enzyme that catalyzes the chemical reaction L-pipecolate + O2 2,3,4,5-tetrahydropyridine-2-carboxylate + H2O2 Thus, the two substrates of this enzyme are L-pipecolate and O2, whereas its two products are 2,3,4,5-tetrahydropyridine-2-carboxylate and H2O2. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with oxygen as acceptor. The systematic name of this enzyme class is L-pipecolate:oxygen 1,6-oxidoreductase. Other names in common use include pipecolate oxidase, and L-pipecolic acid oxidase. This enzyme participates in lysine degradation. References EC 1.5.3 Enzymes of unknown structure
