Abstract excerpt
Winged bean chymotrypsin trypsin inhibitor (WbCTI) is a Kunitz type serine protease inhibitor that inhibits both trypsin and chymotrypsin at 1:1 molar ratio. Site-directed mutagenesis study was employed to generate two mutants of WbCTI, with an aim to explore its dual inhibitory properties against the proteases. The mutants were expressed in Escherichia coli and, were purified to homogeneity using a single step...
