The TransMembrane Protein Helix-Packing Database (TMPad) is an integrated repository of experimentally determined structural folds derived from helix-helix interactions in alpha-helical membrane proteins. TMPad includes geometric descriptors of helix-helix interactions, topology, lipid accessibility, ligand and binding sites information. In addition, TMPad provides structural classification and visualization of the above structural features of TM helix-packing.
