摘要：

Thermodynamic and kinetic parameters for the binding of the bovine basic bancreatic trypsin inhibitor (BPTI, Kunitz inhibitor) to human Glu1-, Lys77-, Val442- and Val561-plasmin (EC 3.4.21.7) have been determined between pH 3.0 and 9.5, and from 5.0 to 45.0°C. The inhibitor-binding properties to human Glu1-, Lys77-, Val442-and Val561-plasmin suggest a possible role of BPTI in modulating plasmin activity when the inhibitor is used therapeutically. © 1990.
