Figure 4.
Fig. 4. Stereoview of the antibody-combining site of the 34E4-hapten complex. Hydrogen bonds are shown as broken lines, and heavy and light chains are colored in blue and green, respectively. The hapten is sandwiched between two aromatic residues TrpL91 and TyrH100D. GluH50 forms a bidentate salt bridge to the guanidinium moiety of the hapten. The CDRs of the light and heavy chains are labeled L1-L3 and H1-H3, respectively.
