Figure 1.

Schematic view of the OspA–Fab 184.1 complex. OspA is displayed with its secondary structural elements, β-strands (cyan, numbered 1–21) and α-helix (magenta, labeled α), connected by grey turns or loops. The front face of the central sheet, as defined in the text, is seen in this view. Fab 184.1 is represented by violet and green ribbons for the light and heavy chains, respectively. The three complementarity determining region (CDR) loops on each chain are displayed as thin ropes and labeled (e.g., L1 for CDR1 of the light chain). The figure was generated with setor (21).
