In enzymology, a pyridoxine 4-dehydrogenase (EC 1.1.1.65) is an enzyme that catalyzes the chemical reaction
- pyridoxine + NADP+ 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 donor with NAD+ or NADP+ as acceptor. 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.
