FAB ANTIBODY FRAGMENT OF AN C60 ANTIFULLERENE ANTIBODY
|
Overview
We have prepared a monoclonal Buckminsterfullerene specific antibody and, report the sequences of its light and heavy chains. We also show, by x-ray, crystallographic analysis of the Fab fragment and by model building, that, the fullerene binding site is formed by the interface of the antibody, light and heavy chains. Shape-complementary clustering of hydrophobic, amino acids, several of which participate in putative stacking, interactions with fullerene, form the binding site. Moreover, an induced, fit mechanism appears to participate in the fullerene binding process., Affinity of the antibody-fullerene complex is 22 nM as measured by, competitive binding. These findings should be applicable not only to the, use of antibodies to assay and direct potential fullerene-based drug, design but could also lead to new methodologies for the production of, fullerene derivatives and nanotubes as well.
