Glossary: L-arogenate = 1-[(2S)-2-amino-2-carboxyethyl]-4-hydroxycyclohexa-2,5-diene-1-carboxylate
Other name(s): arogenic dehydrogenase (ambiguous); cyclohexadienyl dehydrogenase (ambiguous); pretyrosine dehydrogenase (ambiguous); L-arogenate:NAD+ oxidoreductase; arogenate dehydrogenase (NAD+)
Systematic name: L-arogenate:NAD+ oxidoreductase (decarboxylating)
Comments: Arogenate dehydrogenases may utilize NAD+ (EC 1.3.1.43), NADP+ (EC 1.3.1.78), or both (EC 1.3.1.79). NAD+-specific enzymes have been reported from some bacteria [2] and plants [3]. Some enzymes also possess the activity of EC 1.3.1.12, prephenate dehydrogenase.
