EC - Quinate/shikimate dehydrogenase

  IntEnz view ENZYME view

IntEnz Enzyme Nomenclature


Accepted name:
quinate/shikimate dehydrogenase
Other names:
quinate dehydrogenase
quinic dehydrogenase
Systematic name:
L-quinate:NAD(P)+ 3-oxidoreductase



The enzyme is found in bacteria (mostly, but not exclusively, Gram-positive bacteria), fungi, and plants. It participates in the degradation of quinate and shikimate with a strong preference for NAD+ as a cofactor. While the enzyme can act on both quinate and shikimate, activity is higher with the former.
