In enzymology, glycine dehydrogenase (EC 1.4.1.10) is an enzyme that catalyzes the chemical reaction

+ NAD+
 
 
H2O
H+
Glycine dehydrogenase
H2O
H+
 
+ NADH + NH3
 

The three substrates of this enzyme are glycine, water, and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are glyoxylic acid, reduced NADH, ammonia, and a proton. [1] [2]

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH2 group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is glycine:NAD+ oxidoreductase (deaminating).

This should not be confused with:

the glycine dehydrogenase (decarboxylating), which is another name for the glycine cleavage system P-protein (EC 1.4.4.2).

or the glycine dehydroganse (cyanide forming) (EC 1.4.99.5).

or the glycine dehydrogenase (cytochrome) (EC 1.4.2.1).
