In enzymology, pyridoxine 5-dehydrogenase (EC 1.1.99.9) is an enzyme that catalyzes the chemical reaction

 
 
 
 
 
 
isopyridoxal
+ reduced acceptor
 

The two substrates of this enzyme are pyridoxine and an electron acceptor. Its products are isopyridoxal and the corresponding reduced acceptor.[1][2]

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with other acceptors. The systematic name of this enzyme class is pyridoxine:acceptor 5-oxidoreductase. Other names in common use include pyridoxal-5-dehydrogenase, pyridoxol 5-dehydrogenase, pyridoxin 5-dehydrogenase, pyridoxine dehydrogenase, pyridoxine 5'-dehydrogenase, and pyridoxine:(acceptor) 5-oxidoreductase. This enzyme participates in vitamin B6 metabolism. It has 2 cofactors: FAD, and PQQ.
