The 3 substrates of this enzyme are phenylacetaldehyde, NAD+, and H2O, whereas its 3 products are phenylacetate, NADH, and H+.

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 phenylacetaldehyde:NAD+ oxidoreductase. This enzyme participates in phenylalanine metabolism and styrene degradation.
