Structure-based analysis of protein binding pockets using von Neumann entropy

Abstract

Protein binding sites are regions where interactions between a protein and ligand take place. Identification of binding sites is a functional issue especially in structure-based drug design. This paper aims to present a novel feature of protein binding pockets based on the complexity of corresponding weighted Delaunay triangulation. The results demonstrate that candidate binding pockets obtain less relative Von Neumann entropy which means more random scattering of voids inside them. © 2014 Springer International Publishing Switzerland.
