In enzymology, arogenate dehydrogenase (NADP+) () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are L-arogenic acid (shown as its conjugate base arogenate) and oxidised nicotinamide adenine dinucleotide phosphate (NADP<sup>+</sup>). Its products are L-tyrosine, reduced NADPH, and carbon dioxide.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is L-arogenate:NADP+ oxidoreductase (decarboxylating). Other names in common use include arogenic dehydrogenase (ambiguous), pretyrosine dehydrogenase (ambiguous), TyrAAT1, TyrAAT2, and TyrAa.
