In enzymology, 4-hydroxyphenylacetaldehyde dehydrogenase (EC 1.2.1.53) is an enzyme that catalyzes the chemical reaction

+ NAD+

H+
H2O
H+
 
 

The three substrates of this enzyme are 4-hydroxyphenylacetaldehyde, oxidised nicotinamide adenine dinucleotide (NAD+), and water. Its products are 4-hydroxyphenylacetic 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-hydroxyphenylacetaldehyde:NAD+ oxidoreductase. This enzyme is also called 4-HPAL dehydrogenase. This enzyme participates in tyrosine metabolism.
