Thrombin was prepared as described (Skrzpczak-Jankun et al., 1991). Thrombin (1.0 mg/ml in 50 mM HEPES, 50 % glycerol, pH 7.0) was incubated with 1.0 mM acetyl-hirudin, 10 mM 4-iodobenzo[b]thiophene-2-carboxamidine for 1 hr at 4 deg C. Glycerol was removed andthe complex concentrated with a centricon 10 (Amicon) to about 10 mg/ml as determined by the Biorad protein assay kit using bovine serum albumin. Crystals of thrombin-acetyl-hirudin-4-iodobenzo[b]thiophene-2-carboxamidine were grown in hanging drops by vapor diffusion after streak seeding. The drops were made from 5 microliters of complex and 5 microliters of reservoir solution (0.10 M Tris,0.50 M NaCl, 22 % (by volume) PEG 4K, pH 7.5)., VAPOR DIFFUSION 分辨率 1.50 Å R-free 0.246
