Aldehyde dehydrogenase-2 (ALDH2) catalyzes the bioactivation of nitroglycerin (glyceryl trinitrate, GTN) in blood vessels, resulting in vasodilation by nitric oxide (NO) or a related species. Because the mechanism of this reaction is still unclear we determined the three-dimensional structures of wild-type (WT) ALDH2 and of a triple mutant of the protein(More)
Aldehyde dehydrogenase-2 (ALDH2) catalyzes vascular bioactivation of the antianginal drug nitroglycerin (GTN) to yield nitric oxide (NO) or a related species that activates soluble guanylate cyclase (sGC), resulting in cGMP-mediated vasodilation. Accordingly, established ALDH2 inhibitors attenuate GTN-induced vasorelaxation in vitro and in vivo. However,(More)
Background Aldehdyde dehydrogenase-2 (ALDH2) is essential for the detoxification of ethanol in the liver but also catalyzes vas-cular bioactivation of nitroglycerin (glycerol trinitrate, GTN) to its active metabolite nitric oxide (NO), which causes vasodilation through accumulation of cyclic GMP. The clinical use of GTN as a vasodilator is hampered by loss(More)
