  • PubMed Abstract: 
  • The structure of the anti-C 60 fullerene antibody Fab fragment (FabC 60 ) was solved by X-ray crystallography. The computer-aided docking of C 60 into the antigen-binding pocket of FabC 60 showed that binding of C 60 to FabC 60 is governed by the enthalpy and entropy; namely, by π-π stacking interactions with aromatic residues of the antigen-binding site and reduction of the solvent-accessible area of the hydrophobic surface of C 60 ...

    The structure of the anti-C 60 fullerene antibody Fab fragment (FabC 60 ) was solved by X-ray crystallography. The computer-aided docking of C 60 into the antigen-binding pocket of FabC 60 showed that binding of C 60 to FabC 60 is governed by the enthalpy and entropy; namely, by π-π stacking interactions with aromatic residues of the antigen-binding site and reduction of the solvent-accessible area of the hydrophobic surface of C 60 . A fragment of the mobile CDR H3 loop located on the surface of FabC 60 interferes with C 60 binding in the antigen-binding site, thereby resulting in low antibody affinity for C 60 . The structure of apo-FabC 60 has been deposited with pdbid 6H3H.
