L-quinate:NAD(P)+ 3-oxidoreductase

(1) L-quinate + NAD(P)+ = 3-dehydroquinate + NAD(P)H + H+ [RN:R01872 R06846];
(2) shikimate + NAD(P)+ = 3-dehydroshikimate + NAD(P)H + H+ [RN:R02413 R06847]

L-quinate [CPD:C00296];
NAD+ [CPD:C00003];
NADP+ [CPD:C00006];
shikimate [CPD:C00493]

This is the second shikimate dehydrogenase enzyme found in Escherichia coli and differs from EC 1.1.1.25, shikimate dehydrogenase, in that it can use both quinate and shikimate as substrate and either NAD+ or NADP+ as acceptor.
