Arogenate dehydrogenase

In enzymology, an arogenate dehydrogenase (EC number|1.3.1.43) is an enzyme that catalyzes the chemical reaction

:L-arogenate + NAD⁺ $ightleftharpoons$ L-tyrosine + NADH + CO₂

Thus, the two substrates of this enzyme are L-arogenate and NAD⁺, whereas its 3 products are L-tyrosine, NADH, and CO₂.

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:NAD+ oxidoreductase (decarboxylating). Other names in common use include arogenic dehydrogenase (ambiguous), cyclohexadienyl dehydrogenase, pretyrosine dehydrogenase (ambiguous), and L-arogenate:NAD+ oxidoreductase. This enzyme participates in phenylalanine, tyrosine and tryptophan biosynthesis and novobiocin biosynthesis.

tructural studies
