In enzymology, pyridoxal 4-dehydrogenase (EC 1.1.1.107) is an enzyme that catalyzes the chemical reaction

+ NAD+
 
 
 
H+
Pyridoxal 4-dehydrogenase
 
H+
 
+ NADH
 

The two substrates of this enzyme are pyridoxal and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 4-pyridoxolactone, reduced NADH, and a proton. [1] [2]

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 pyridoxal:NAD+ 4-oxidoreductase. This enzyme is also called pyridoxal dehydrogenase. This enzyme participates in vitamin B6 metabolism.
