The Automated Topology Builder (ATB) and Repository is intended to facilitate the development of molecular force fields for Molecular Dynamics or Monte Carlo simulations of biomolecular systems. Applications include the study of biomolecule:ligand complexes, free energy calculations, structure-based drug design and refinement of x-ray crystal complexes.
KEGG (Kyoto Encyclopedia of Genes and Genomes) is a bioinformatics resource for linking genomes to life and the environment
