Docking of DNC with MMP-2. A MMP-2-DNC complex magnified. B MMP-2 structure is shown as ribbon, α-Helix is red, β-sheet is blue, coil is light gray, involved amino acids in complex are element gray, ligand is yellow stick, and H-Bond is dotted line green. C LigPlot of the MMP-2-DNC complex. Ligand is yellow, involved amino acids in complex are purple, H-Bonds are dot-ted line green, and side residues are red
