Glossary: L-arogenate = 1-[(2S)-2-amino-2-carboxyethyl]-4-hydroxycyclohexa-2,5-diene-1-carboxylate
Other name(s): arogenic dehydrogenase (ambiguous); cyclohexadienyl dehydrogenase; pretyrosine dehydrogenase (ambiguous)
Systematic name: L-arogenate:NAD(P)+ oxidoreductase (decarboxylating)
Comments: Arogenate dehydrogenases may utilize NAD+ (EC 220.127.116.11), NADP+ (EC 18.104.22.168), or both (EC 22.214.171.124). Enzymes that can utilize both cofactors have been reported from some Proteobacteria, including Burkholderia caryophylli, Burkholderia cepacia, Pseudomonas marginata and Delftia acidovorans.
