Abstract:

An immobilized double-headed inhibitor from Phaseolus vulgaris L. selectively binds the trypsin-like enzyme produced by Streptomyces griseus. Binding takes place at pH 8.0, and at pH 2.0 the protease can be quantitatively released from the complex. Purified by affinity chromatography, the trypsin-like enzyme is homogeneous according to polyacrylamide gel electrophoresis and ultracentrifugation data. Physico-chemical and enzymic properties of the enzyme are identical to those exhibited by the enzyme purified by ion-exchange chromatography. Chymoelastases from Str. griseus as well as the subtilisin-like enzyme do not interact with an immobilized inhibitor. In solution, the inhibitor from P. vulgaris gives a stable ternary complex with bovine trypsin and chymotrypsin, whereas with an immobilized inhibitor the trypsin, if present, tends to displace chymotrypsin in an chymotrypsin inhibitor complex. This evidence suggests that immobilization results in considerable changes in inhibitor properties.
