- an aldehyde + NAD(P)+ + H2O an acid + NAD(P)H + H+
The 4 substrates of this enzyme are aldehyde, NAD+, NADP+, and H2O, whereas its 4 products are acid, NADH, NADPH, 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 aldehyde:NAD(P)+ oxidoreductase. Other names in common use include aldehyde dehydrogenase [NAD(P)+], and ALDH. This enzyme participates in 5 metabolic pathways: glycolysis / gluconeogenesis, histidine metabolism, tyrosine metabolism, phenylalanine metabolism, and metabolism of xenobiotics by cytochrome p450.
Structural studies
