Kinetic analysis of purified SSTI. Noncompetitive (mixed) type of inhibition of bovine trypsin (A) Michaelis–Menten kinetics of bovine trypsin in presence and in absence of SSTI. (B) Lineweaver–Burk plot of 1/[V] versus 1/[S] of bovine trypsin in presence and in absence of SSTI. (C) Dixon’s plot of 1/[V] versus [I] of bovine trypsin in presence of different concentrations of SSTI at two different concentrations of BApNA. The Ki value for SSTI was 16.6 × 10−8 M. (D) Interaction by Isothermal titration of purified SSTI with bovine trypsin.
