IntEnz Enzyme Nomenclature


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



This is the second shikimate dehydrogenase enzyme found in Escherichia coli. It can use both quinate and shikimate as substrates and either NAD+ or NADP+ as acceptor. The low catalytic efficiency with both quinate and shikimate suggests that neither may be the physiological substrate. cf. EC, quinate/shikimate dehydrogenase (NAD+), EC, quinate/shikimate dehydrogenase (quinone), and EC, shikimate dehydrogenase (NADP+).
