The molecular-modeling software Bio is a versatile tool for constructing, analyzing and minimizing molecular structures. The implemented minimizer is based on a directional force field for hydrogen bonds and metal-ligand interactions. The software includes functional-group templates and user-expandable databases for organic molecules, carbohydrates, peptides, and nucleic acids. Bio allows for H-bond network orientation, full, zone or constrained refinement, ligand superposition (best fit), visual bump check during docking, dynamic torsion-angle manipulation, and mutation/completion of amino-acid residues.
