General annotation (Comments)

Function	Bifunctional enzyme that catalyzes two sequential steps of the aromatic amino acids biosynthetic pathway. The first reaction is catalyzed by the 3-dehydroquinate dehydratase, coded by the aroD domain; the second reaction is catalyzed by the shikimate 5-dehydrogenase, coded by the aroE domain.
Catalytic activity	3-dehydroquinate = 3-dehydroshikimate + H(2)O. Shikimate + NADP(+) = 3-dehydroshikimate + NADPH.
Pathway	Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and PEP: step 3/7. Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and PEP: step 4/7.
Sequence similarities	In the N-terminal section; belongs to the type-I 3-dehydroquinase family. In the C-terminal section; belongs to the shikimate dehydrogenase family.
