Figure 4From: ProteinVolume: calculating molecular van der Waals and void volumes in proteins The size scaling behavior of geometric of volumes of proteins. Panel A. Dependence of the molecular surface volume (circles, VMS), the van der Waals volume (triangles, VVDW) and void volumes (upside-down triangles, VVoid) on number of amino acid residues in proteins (Naar). Panel B. Dependence of fraction of void volume on protein size.Back to article page
