L-arogenate:NAD+ oxidoreductase (decarboxylating)
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.

LITERATURE
malfunction
-
a maize opaque endosperm mutant (mto140), which shows retarded vegetative growth, is described. The opaque phenotype co-segregates with a mutator transposon insertion in an arogenate dehydrogenase gene (zmAroDH-1). Mto140/arodh-1 seeds show a general reduction in zein storage protein accumulation and an elevated lysine phenotype typical of other opaque endosperm mutants; a mutator insertion at an equivalent position in AroDH-3, the most closely related family member to AroDH-1, is associated with opaque endosperm and stunted vegetative growth phenotypes
