3A2 is an antibody raised against human chorionic gonadotropin and, recognizes a linear epitope on the C-terminal peptide of the human, chorionic gonadotropin beta-subunit. Its three-dimensional structure has, been determined to 2-A resolution using molecular replacement and refined, to a conventional R-factor of 18.2%. The protein exhibits the typical, immunoglobulin fold, and the model contains 944 ordered water molecules, and one sulfate ion. A comparison of the complementarity-determining, regions of the Fab3A2 with those from the Protein Data Bank following the, canonical structure method reveals a canonical main chain conformation., This antibody belongs to the canonical structure class (combination of, canonical conformations of the complementarity determining loops) that, shows a preference for haptens and not for peptides. However, the shape of, the surface of the antigen binding loops resembles that of an anti-peptide, antibody.
