Arogenate dehydrogenases may utilize NAD+ (EC 126.96.36.199), NADP+ (EC 188.8.131.52), or both (EC 184.108.40.206). Enzymes that can utilize both cofactors have been reported from some Proteobacteria, including Burkholderia caryophylli, Burkholderia cepacia, Pseudomonas marginata and Delftia acidovorans.
