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 for 1 hr at 4 deg C. Glycerol was removed and the 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 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 8.20)., VAPOR DIFFUSION | |||||||||||||||||||||||||||||||||||

No density was observed for Trp148, Thr149, Ala149A, Asn149B, Val149C, Gly149D, and Lys149E in the autolysis loop, and these residues are not included in the model. Disordered waters include: HOH395 which is in a special position; HOH396 is close to a symmetry related equivalent of itself; HOH422 which is close to HOH432; HOH434 is close to a symmetry related equivalent of itself; HOH447 which is close to HOH494; (THE ABOVE WATERS HAVE VERY STRONG DENSITY AND THEIR REFINED OCCUPANCIES ARE SIGNIFICANTLY GREATER THAN UNITY. THEY MAY REFLECT A DIFFERENT STRUCTURAL FEATURE THAN DISORDERED WATERS). HOH495 which is close to HOH499; HOH504 which is close to HOH506; HOH578 which is close to a symmetry-related equivalent of HOH579; HOH580 WHICH IS CLOSE TO HOH578 AND TO A SYMMETRY-RELATED EQUIVALENT OF HOH579; HOH652 WHICH IS CLOSE TO HOH759; HOH687 WHICH IS CLOSE TO HOH688; HOH717 WHICH IS CLOSE TO THE SIDE CHAIN OF LYS_H145; HOH733 WHICH IS CLOSE TO THE SIDE CHAIN OF SER_L1E; HOH786 IS CLOSE TO A SYMMETRY RELATED EQUIVALENT OF ITSELF.
