Docked complexes of PGIP (ribbon representation in blue) and FmPG (space-filling representation in red). A and C show how PvPGIP2 (blue) and GmPGIP3 (blue) respectively, hinder the substrate binding site and block the active site cleft of FmPG (red). The only model of the PvPGIP1-FmPG complex where PvPGIP1 (blue) docks near the active site of FmPG (red) although not blocking it unlike the other two complexes, is shown in B. The marked area shown by the yellow ellipse in B indicates the portion of FmPG that PvPGIP1 has been unable to block.
