    Abstract:
    A phage peptide library was used to select peptides interacting with virus-neutralizing monoclonal antibodies (mAb) 2G12 which recognize a discontinuous surface epitope of HIV-1 gp120. With the published X-ray data, gp120 regions involved in the antigenic determinant were predicted. Binding with mAb 2G12 was ascribed to Trh-297, Phe-383, Tyr-384, Arg-419, Ile-420, Thr-415, Leu-416, Pro-417, Lys-421, and Trp-112. Though distant in the gp120 sequence, these residues are close in space and form the 2G12 epitope on the gp120 surface.
