In enzymology, a 4-hydroxymuconic-semialdehyde dehydrogenase (EC 1.2.1.61) is an enzyme that catalyzes the chemical reaction

4-hydroxymuconic semialdehyde
+ NAD+
 
 
H2O
H+
H2O
H+
 
 

The three substrates of this enzyme are 4-hydroxymuconic semialdehyde, oxidised nicotinamide adenine dinucleotide (NAD+), and water. Its products are maleylacetic acid, reduced NADH, and a proton.[1][2]

This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 4-hydroxymuconic-semialdehyde:NAD+ oxidoreductase. This enzyme participates in gamma-hexachlorocyclohexane degradation.
