Abstract
Abstract: In this study we propose to transform protein-ligand interactions into three-dimensional geometric networks, from which recurring network substructures, or network motifs, are selected and used to provide probability-ranked interaction templates with which to score protein-ligand docking solutions. A novel scoring function, MotifScore, was developed, which is non-energy-based, and docking is, instead, scored by counting the occurrences of motifs of protein-ligand interaction networks constructed using structures of protein-ligand complexes. Evaluation on a benchmark test set showed that MotifScore performed well compared to several energy-based scoring functions. (Xie & Hwang, BMC Bioinformatics 2010, 11:298).
