+ NADH
 

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.
