Figure 3. Residue-specific contacts on MMP-2 with Gd@C82(OH)22 and C82(OH)22.

Figure 3

(a) Gd@C82(OH)22 has a favorable contact with MMP-2 specifically at both the ligand specificity S1′ loop and Zn2+-coordinated active site. (b) C82(OH)22 contacts are reduced in both the S1′ and the active site of MMP-2, while interactions with upper rim residues largely remain.
