A combinatorial ligand design approach based on the multiple copy simultaneous search (MCSS) method and a simple scheme for joining MCSS functional group sites was applied to the binding pocket of P3/Sabin poliovirus and rhinovirus 14. The MCSS method determines where specific functional (chemical)

Abstract
A new method is proposed for determining energetically favorable positions and orientations for functional groups on the surface of proteins with known threeβdimensional structure. From 1,000 to 5,000 copies of a functional group are randomly placed in the site and subjected to simultaneous energy minimization and/or quenched molecular dynamics. The resulting functionality maps of a protein receptor site, which can take account of its flexibility, can be used for the analysis of protein ligand interactions and rational drug design. Application of the method to the sialic acid binding site of the influenza coat protein, hemagglutinin, yields functional group minima that correspond with those of the ligand in a cocrystal structure.

We offer a novel graphical method for determining the number of essential sites in enzymes that contain multiple binding sites for a ligand. This method is applicable both to monomeric enzymes containing multiple "unspecific" sites (for protons, metal ions, etc.) and to oligomeric enzymes containing
