For each protein chain in the database, the following protein graph types are available:

• the alpha graph: Contains all helices of the chain (vertices) and their 3D contacts (edges).
• the beta graph: Contains all beta strands of the chain and their 3D contacts.
• the the alpha-beta graph: Also known as the albe graph. Contains all helices and strands of the chain and their 3D contacts.
• the alpha-ligand graph: Contains all helices and ligands of the chain and their 3D contacts.
• the beta-ligand graph: Contains all beta strands and ligands of the chain and their 3D contacts.
• the the alpha-beta-ligand graph: Also known as the albelig graph. Contains all helices, strands, and ligands of the chain and their 3D contacts.
