Alanine dehydrogenase () is an enzyme that catalyzes the chemical reaction
The three substrates of this enzyme are alanine, water, and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are pyruvic acid, reduced NADH, ammonia, and a proton.
This enzyme participates in taurine and hypotaurine metabolism and reductive carboxylate cycle ( fixation).
Nomenclature 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 L-alanine:NAD+ oxidoreductase (deaminating). Other names in common use include AlaDH, L-alanine dehydrogenase, NAD+-linked alanine dehydrogenase, alpha-alanine dehydrogenase, NAD+-dependent alanine dehydrogenase, alanine oxidoreductase, and NADH-dependent alanine dehydrogenase. T
Structure Alanine dehydrogenase contains both a N-terminus and C-terminus domains.
