Figure 2

Illustration of solid angle calculation. (A) A 2D representation of solid angle calculation, where V in is the volume of the virtual sphere located within the interior regions of the query protein (blue circles), and V sphere represents the volume of the total sphere (black circles). (B) Calculated solid angles on the surface area of the query protein (PDB ID: 1TPA). Red spheres are recognized as protruding regions, white or lighter-shaded spheres represent flat regions, and blue spheres represent concave regions on the protein surface.
