In vitro, is able to catalyze the NADP(+)-dependent oxidation of shikimate to 3-dehydroshikimate. However, has much lower activity than classical shikimate dehydrogenases AroE, indicating that shikimate may not be the biological substrate. Cannot utilize NAD(+) instead of NADP(+). Is not able to catalyze the oxidation of quinate. NADP(+) + shikimate = 3-dehydroshikimate + H(+) + NADPH kcat is 0.2 sec(-1). Optimum pH is 8.8. Homodimer. Belongs to the shikimate dehydrogenase-like family.
