Bifunctional dehydroquinate dehydratase-shikimate dehydrogenase enzyme that catalyzes two steps in the chorismate biosynthesis pathway. 3-dehydroquinate = 3-dehydroshikimate + H2O NADP(+) + shikimate = 3-dehydroshikimate + H(+) + NADPH Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 3/7. Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 4/7. Monomer. In the N-terminal section; belongs to the type-I 3-dehydroquinase family. In the C-terminal section; belongs to the shikimate dehydrogenase family.
