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. Resolution 2.43 Å R-free 0.233
