Binding of protein inhibitors. Stefin B superimposed on cathepsin L–p41 complex in views (a) across and (b) along the active-site cleft of cathepsin L. (a) is shown in approximately the standard view (Fig. 1[link]), whereas (b) is generated by an 90° rotation about the vertical axis. Superposition of the p41 fragment and stefin B is based on the three-dimensional alignment of papain and cathepsin L structures in the papain–stefin B and cathepsin L–p41 fragment complexes. Chain traces of the p41 fragment, stefin B and cathepsin L are shown in orange, red and blue, respectively.
