IntEnz Enzyme Nomenclature


Accepted name:
quinate dehydrogenase
Other names:
quinate 5-dehydrogenase
quinate:NAD oxidoreductase
quinate:NAD+ 5-oxidoreductase
quinic dehydrogenase
Systematic name:
L-quinate:NAD+ 3-oxidoreductase



The enzyme is specific for quinate as substrate; phenylpyruvate, phenylalanine, cinnamate and shikimate will not act as substrates. NAD+ cannot be replaced by NADP+.
