- (1) L-hinat + NAD(P)+ 3-dehidrohinat + NAD(P)H + H+
- (2) šikimat + NAD(P)+ 3-dehidrošikimat + NAD(P)H + H+
Ovo je drugi enzim šikimatne dehidrogenaze nađen kod Escherichia coli. On se razlikuje od EC 1.1.1.25, šikimatne dehidrogenaze, po tome što može da koristi hinat I šikimat kao supstrat, i bilo NAD+ ili NADP+ kao akceptor.
