Crystal structure of a cyclic form of bovine pancreatic trypsin inhibitor.
The crystal structure of a cyclic form of a mutant of bovine pancreatic trypsin inhibitor has been solved at 1.0 A resolution. The protein was synthesized by native chemical ligation and its structure is almost indistinguishable from the previously described recombinant form of the same mutant; however, the new loop containing the former termini became much better ordered.
متن کاملStructure of form III crystals of bovine pancreatic trypsin inhibitor.
The structure of bovine pancreatic trypsin inhibitor has been solved in a new crystal form III. The crystals belong to space group P2(1)2(1)2 with a = 55.2 A, b = 38.2 A, c = 24.05 A. The structure was solved on the basis of co-ordinates of forms I and II of the inhibitor by molecular replacement, and the X-ray data extending to 1.7 A were used in a restrained least-squares refinement. The fina...
متن کاملThe crystal structure of anionic salmon trypsin in complex with bovine pancreatic trypsin inhibitor.
The complex formed between anionic salmon trypsin (ST) and bovine pancreatic trypsin inhibitor (BPTI) has been crystallised, and the X-ray structure has been solved using the molecular replacement method. The crystals are hexagonal and belong to space group P6(1)22 with lattice parameters of a = b = 83.12 A and c = 222.15 A. Data have been collected to 2.1 A and the structure has been refined t...
متن کاملExploring bovine pancreatic trypsin inhibitor phase transitions.
This paper presents an investigation of the phase diagram of BPTI (bovine pancreatic trypsin inhibitor)/350 mM KSCN at pH 4.9 by direct observation and numerical simulations. We report optical microscopy and light and X-ray scattering experiments coupled with theoretical data analysis using numerical tools. The phase diagram is thoroughly determined, as a function of temperature. Two polymorphs...
متن کاملTrypsin inhibitor from bovine pancreatic juice.
A trypsin inhibitor has been isolated in 54% yield from bovine pancreatic juice by gel filtration on Sephadex G-75 at pH 8.1 and by elution chromatography on DEAE-cellulose at pH 9.0. It appears to be homogeneous by equilibrium chromatography, equilibrium sedimentation ultracentrifugation, and amino acid analysis, and on the basis of the stoichiometry of its interaction with trypsin. The polype...
