Project Summery

Rapidly accumulating genome sequence data and protein tertiary structures, together with recent advance of bioinformatics techniques open a new way of computational systematic drug discovery. In the post-genomic era, utilizing established knowledge of protein structure function relationship in bioinformatics field is a promising strategy for cost-effective rational drug development. Our project is focused on development computational methods for comparing ligand binding sites and ligand binding sites with ligands. The methods we will develop can effectively capture similarity and dissimilarity of geometrical and physicochemical features of local protein 3D surfaces. We employ projection-based method, 3D Zernike Descriptor, to enable fast comparison.
