X-ray crystallization conditions VAPOR DIFFUSION, SITTING DROP；pH 5；291 K；Grid Salt screen H8 : 4.0M NaCl, 0.1M Citric acid/citrate, pH 5.0. CrpaA.01302.a.B2.PW39348 at 21.9 mg/mL. 2mM inhibitor added to the protein prior to crystallization. plate 19968 H8 drop 1, Puck: PSL-1107, Cryo: 2.5M Lithium sulfate. The data were somewhat anisotropic which produced residual density (Fo-Fc) thoughout the polypeptide. The anisotropically truncated data from staraniso were used for refinement. The original and anisotropic truncated data were both deposited.
