Other name(s): shikimate dehydrogenase; dehydroshikimic reductase; shikimate oxidoreductase; shikimate:NADP+ oxidoreductase; 5-dehydroshikimate reductase; shikimate 5-dehydrogenase; 5-dehydroshikimic reductase; DHS reductase; shikimate:NADP+ 5-oxidoreductase; AroE
Systematic name: shikimate:NADP+ 3-oxidoreductase
Comments: NAD+ cannot replace NADP+ [3]. In higher organisms, this enzyme forms part of a multienzyme complex with EC 4.2.1.10, 3-dehydroquinate dehydratase [4]. cf. EC 1.1.1.24, quinate/shikimate dehydrogenase (NAD+), EC 1.1.5.8, quinate/shikimate dehydrogenase (quinone), and EC 1.1.1.282, quinate/shikimate dehydrogenase [NAD(P)+].
