Bifunctional enzyme that catalyzes two sequential steps of the aromatic amino acids biosynthetic pathway. In the first reaction, the AroD domain catalyzes the cis-dehydration of 3-dehydroquinate (DHQ) and introduces the first double bond of the aromatic ring to yield 3-dehydroshikimate; in the second reaction, the AroE domain catalyzes the reversible NADPH linked reduction of 3-dehydroshikimate (DHSA) to yield shikimate (SA). 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. In the N-terminal section; belongs to the type-I 3-dehydroquinase family. In the C-terminal section; belongs to the shikimate dehydrogenase family. Extended N-terminus.
