Fig. 5From: Structural basis to identify a target site in Shiga toxin for the inhibitor discovery against growth of Shiga toxin-producing E. colia Covariance matrix indicate coupling between residues, where red represents correlated, white represents uncorrelated and blue represents anti-correlated motions of residues. Black boxes represent relative movement of residues positioned at 50–100 or 250–300. These regions covered the Y77 and E259 regions. b Ramachandran plot of the Stx2-TVP complex. The red-colored boxes represent most favored regions. Additional allowed regions are denoted by yellow color boxesBack to article page
