Representation of the VH/VL packing angle in the 1bgx structure. (A) Shows the ribbon structure of the VH and VL in green and cyan, respectively. The conserved residues used to define the packing angle are shown in red. The regression lines, fitted on the Cα atoms of these residues are shown in red dashed lines. (B) Shows the heavy chain variable domain of the 1bgx structure and (C) shows the light chain variable domain of the 1bgx structure.
