How can I obtain a non-redundant (or representative) set of PDB structures?
Sources: [6] [7] (Some more to add.) A: There are several sources for non-redundant subsets of PDB chains, including: • PDB (see [8]) • PDBSELECT • PISCES For non-redundant sets of protein complexes, try: • http://www.3dcomplex.org For non-redundant sets of domains, use SCOP or CATH. Specifically you can obtain non-redundant sets of SCOP domain sequences via the ASTRAL database server.
