In enzymology, a L-pipecolate dehydrogenase () is an enzyme that catalyzes the chemical reaction L-pipecolate + acceptor 2,3,4,5-tetrahydropyridine-2-carboxylate + reduced acceptor Thus, the two substrates of this enzyme are L-pipecolate and acceptor, whereas its two products are 2,3,4,5-tetrahydropyridine-2-carboxylate and reduced acceptor. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with other acceptors. The systematic name of this enzyme class is L-pipecolate:acceptor 1,6-oxidoreductase. This enzyme is also called L-pipecolate:(acceptor) 1,6-oxidoreductase. This enzyme participates in lysine degradation. References EC 1.5.99 Enzymes of unknown structure
