binding sites

1 concave features on antibody molecules that serve as locations for binding antigens. Because of possible variations in antibody amino acid sequences and molecule configurations, each kind of antibody can provide combining sites for a specific antigen.
2 locations on protein molecules where drugs or other substances may become bound by intermolecular forces or electrochemical attraction.
