The two substrates of this enzyme are 4-hydroxybutanoic acid, and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are succinic semialdehyde, reduced NADH, and a proton.[1]
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor.[2] The systematic name of this enzyme class is 4-hydroxybutanoate:NAD+ oxidoreductase. This enzyme is also called gamma-hydroxybutyrate dehydrogenase. This enzyme participates in butanoate metabolism and the degradation of the neurotransmitter 4-hydroxybutanoic acid.[3]
