Improving the prediction of protein binding sites by combining heterogeneous data and Voronoi diagrams

Joan Segura, Pamela F Jones, Narcis Fernandez-Fuentes
2011 BMC Bioinformatics  
The method makes use of broad set of heterogeneous data and defined of residue environment, by means of Voronoi Diagrams that are integrated by a two-steps Random Forest ensemble classifier.  ...  Protein binding site prediction by computational means can yield valuable information that complements and guides experimental approaches to determine the structure of protein complexes.  ...  This work was supported by the Research Councils United Kingdom (RCUK) Academic Fellow scheme (to NFF) and an internal scholarship awarded by the Leeds Institute of Molecular Medicine (to JM).  ...
