The enzyme 1,2-dihydroxy-6-methylcyclohexa-3,5-dienecarboxylate dehydrogenase uses 1,2-dihydroxy-6-methylcyclohexa-3,5-dienecarboxylate and NAD+ to produce 3-methylcatechol, NADH and CO2.
Aryl-alcohol dehydrogenase uses an aromatic alcohol and NAD+ to produce an aromatic aldehyde, NADH and H+.
The oxidative or reductive capacity of the enzyme is regulated by NADH produced by hexose-6-phosphate dehydrogenase (H6PD).
The enzyme Taxifolin 8-monooxygenase uses taxifolin, NADH, NADPH, H+, and O2 to produce 2,3-dihydrogossypetin, NAD+, NADP+, and H2O.
Usually, in the presence of NADPH dehydrogenase or NADH dehydrogenase as the enzyme, NADPH or NADH is the reductant that converts resazurin to resorufin.
