X-RAY DIFFRACTION 5.3 291 Human BACE protein containing residues 57-453 and a C-terminal 6His-tag was concentrated to 6mg/ml in buffer 0.1M borate pH 8.5. Compound was added to give a final molar access of compound:protein of 8:1. Protein and compound were then incubated on ice for 1 hour. The drops were set up with a 1:1(v/v) ratio of protein to mother liquor in a total volume of 2 ul. Diffraction quality crystals of BACE in complex with compound was obtained by sitting-drop vapor diffusion method at 291K against a reservoir containing 0.1 M sodium acetate, 2% PEG8000, VAPOR DIFFUSION, SITTING DROP
