1 Protein monomer Monomer Protein × 1 PDB declaration: monomeric(1) Consistent with protein copy count Chain A; UniProt 48–453 Fragment:catalytic domain XLI N-acetyl-L-leucyl-N-[(4S,5S,7R)-8-(butylamino)-5-hydroxy-2,7-dimethyl-8-oxooctan-4-yl]-L-methioninamide × 1 X-RAY DIFFRACTION X-ray crystallization conditions:VAPOR DIFFUSION, HANGING DROP;pH 5.5;292 K;Crystals were grown from 12% (w/v) PEG 8,000, 0.1M KCl, 5% glycerol. Protein stock was 12.7mg/ml BACE in 10mM Tris-HCl pH 7.4, 25mM NaCl, with a 2-fold excess of compound added from a 50mM stock solution in DMSO (0.55% DMSO in drop). Before mounting, the crystals were briefly transferred to a cryo-protectant solution containing 12% (w/v) PEG 8,000, 0.5M KCl, 15% glycerol., VAPOR DIFFUSION, HANGING DROP, temperature 292K Resolution 2.90 Å R-free 0.238
