Make list of PDB identifiers from PDBsum keyword and culledPDB lists.
Using this tool, you make a list of PDB identifiers by specifying a keyword that will be passed to PDBsum. (For instance "serine protease"). You can intersect the results with non redundant lists of the culledPDB at various level of sequence identity. The culledPDB lists are those including all techniques (i.e the inclNOTXRAY files)..
