Modeling of substrate specificity of the Alzheimer's disease amyloid precursor protein beta-secretase.

Abstract excerpt

The enzyme BACE (beta-site APP-cleaving enzyme) has recently been identified as the beta-secretase that cleaves the amyloid precursor protein (APP) to produce the N terminus of the Abeta peptide found in plaques in the brains of Alzheimer's disease patients. BACE is an aspartic protease similar to pepsin and renin. Comparative modeling of the three-dimensional structure of BACE in complex with its substrate shows...
