Molecular interactions supporting the ultralong stalk motif in ultralong Fabs (a, c) D08 and (b, d) D08* from side (a, b) and top-down (c, d) views. Complementarity-determining regions are coloured according to Fig. 1; the D08 heavy chain is in black, the D08 light chain is in red and the BLV5B8 light chain is in magenta, with increasing saturation from CDR1 to CDR3. For clarity, the field of view is focused on the ultralong CDR3H stalk motifs and immediate residues. π-Stacking interactions between aromatics are represented with dashed lines. |
