Activation and Inhibition of Yeast Aldehyde Dehydrogenase Activity by Pantethine and Its Metabolites

Abstract
D-Pantethine-related metabolites, such as taurine, D-pantetheine, coenzyme A and D-pantothenate, activated yeast aldedehyde dehydrogenase in vitro. D-Pantethine and cysteamine hydrochloride, however, strongly inhibited the activity of this enzyme.
