Effects of univalent cations on the properties of yeast NAD+ acetaldehyde dehydrogenase
Abstract
Acetaldehyde dehydrogenase (aldehyde:NAD(P)+ oxidoreductase, EC 1.2.1.5) from yeast is activated by K+ and Rb+. Sodium and Li+ antagonize the activation, apparently by competitive inhibition with K+. The stimulation of activity by mercaptoethanol and the activation by K+ are not additive in a reaction mixture containing both. Potassium and Rb+ in the order just mentioned protect acetaldehyde dehydrogenase from inactivation by heat, whereas Na+ …
