The structure of a complex of the anti‐cholera toxin antibody TE33 Fab (fragment antibody) with theD‐peptidevpGsqhydswas solved to 1.78 Å resolution. TheD‐peptide was derived from the linearL‐peptide epitope VPGSQHIDS by a stepwise transformation. Despite the very similar amino acid sequence—the only difference is a tyrosine residue in position 7—there are marked differences in the individual positions with respect to their contribution to the peptide overall affinity as ascertained by a complete substitutional analysis. This is reflected by the X‐ray structure of the TE33 Fab/D‐peptide complex where there is an inverted orientation of theD‐peptide as compared with the known structure of a corresponding complex containing the epitopeL‐peptide, with the side chains establishing different contacts within the binding site of TE33. TheD‐ andL‐peptide affinities are comparable and the surface areas buried by complex formation are almost the same. Thus the antibody TE33 provides a typical example for polyspecific binding behavior of IgG family antibodies. Copyright © 2007 John Wiley & Sons, Ltd.
