Figure 6.
Fig. 6. Putative structure of active GzmK bound to a substrate/inhibitor. The crystal structure of pro-GzmK (blue) is shown superimposed with a model of active GzmK (red). In addition, the reactive site loop of the second Kunitz-type domain of bikunin (1BIK, residues Gly89-Phe^94, yellow) has been modeled into the active site region using the known complex between BPTI and trypsin as a template. The figure was prepared with WEBLABVIEWER (available at www.msi.com).
