摘要：

A normal mode analysis of bovine pancreatic trypsin inhibitor is carried out by using a Urey-Bradley-Shimanouchi potential energy function. The density of vibrational states, the magnitudes, and time scales of the atomic fluctuations are compared with experimental and theoretical results obtained by the more commonly used potential energy functions. The atomic fluctuations of Lys-15 are subject to extensive considerations as this residue is buried in the trypsin specificity pocket. It is found that Arg-17 is likely to be of importance in order to understand the way BPTI binds on trypsin.
