Abstract

Human BACE polypeptides having modifications to the N-linked glycosylation sites including one or more of the following amino acid substitutions: S174I, N223A, N153Q and N354S. DNA sequences, vectors, and host cells for producing the polypeptides. Crystalline protein compositions formed from the purified polypeptides. Methods of screening for compounds that inhibit Aβ using the polypeptides.
