  • PubMed Abstract: 

    Recent structural results have shown that antibodies use an induced fit mechanism to recognize and bind their antigens. Here we present the crystallographically determined structure of an Fab directed against an HIV-1 peptide (Fab 50.1) in the unliganded state and compare it with the peptide-bound structure. We perform a detailed analysis of the components that contribute to enhanced antigen binding and recognition.
