To increase our understanding of the molecular basis for antibody specificity and for the cross-reactivity of anti-peptide antibodies with native proteins it is important to study the three-dimensional structure of antibody complexes with their peptide antigens. For this purpose it may not be necessary to solve the structure of the whole antibody complex(More)
The principal neutralizing determinant (PND) of human immunodeficiency virus type 1 (HIV-1) is located in the third hypervariable region (V3) of the virus envelope glycoprotein gp120. The conformation of a V3 peptide of HIV-1IIIB bound to the Fab fragment of an anti-gp120 HIV neutralizing antibody, 0.5beta, was studied by 1H NMR spectroscopy. This(More)
The 24-amino-acid peptide RP135 (NNTRKSIRIQRGPGRAFVTIGKIG) corresponds in its amino acid sequence to the principal neutralizing determinant of the human immunodeficiency virus type-1, IIIB isolate (HIV-1IIIB, residues 308-331 of the envelope glycoprotein gp120). In order to map the antigenic determinant recognized by 0.5 beta, the complex of RP135 with an(More)
