Pyridoxine 4-dehydrogenase

In enzymology, a pyridoxine 4-dehydrogenase is an enzyme that catalyzes the chemical reaction


 * pyridoxine + NADP+ $$\rightleftharpoons$$ pyridoxal + NADPH + H+

Thus, the two substrates of this enzyme are pyridoxine and NADP+, whereas its 3 products are pyridoxal, NADPH, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donors with NAD+ or NADP+ as acceptors. The systematic name of this enzyme class is pyridoxine:NADP+ 4-oxidoreductase. Other names in common use include pyridoxin dehydrogenase, pyridoxol dehydrogenase, and pyridoxine dehydrogenase. This enzyme participates in vitamin B6 metabolism.
