Arogenate dehydrogenases may utilize NAD+ (EC 18.104.22.168), NADP+ (EC 22.214.171.124), or both (EC 126.96.36.199). Enzymes that can utilize both cofactors have been reported from some Proteobacteria, including Burkholderia caryophylli, Burkholderia cepacia, Pseudomonas marginata and Delftia acidovorans.
