  • PubMed Abstract: 

    The enzyme 17beta-hydroxysteroid dehydrogenase type 10 (HSD10), also known as amyloid beta-peptide-binding alcohol dehydrogenase (ABAD), has been implicated in the development of Alzheimer's disease. This protein, a member of the short-chain dehydrogenase/reductase family of enzymes, has been shown to bind beta-amyloid and to participate in beta-amyloid neurotoxicity. We have determined the crystal structure of human ABAD/HSD10 complexed with NAD(+) and an inhibitory small molecule. The inhibitor occupies the substrate-binding site and forms a covalent adduct with the NAD(+) cofactor. The crystal structure provides a basis for the design of potent, highly specific ABAD/HSD10 inhibitors with potential application in the treatment of Alzheimer's disease.
