 Examples:

  
 kinase complexed Find all topologies in PTGL containing the phrase kinase complexed in the HEADER-, COMPOUND-, MOLECULE-, SCOP-, CATH- and HETNAM-attributes of the PTGL-database
 complexed and kinase Find all topologies containing the word complexed and the word kinase. This is a larger number of topologies than in the list of entries containing the phrase kinase complexed.
 complexed or kinase Find all topologies containing the word complexed or the word kinase.
 complexed and not kinase Find all topologies containing the word complexed and not the word kinase.
 pdb_id: 4HHB Find the single structure with the PTGL ID of 4HHB. PDB_ID is an example of an attribute.
 header:not phosphotransferase Find all topologies that don't contain the term phosphotransferase in their PTGL HEADER records. HEADER is an example of an attribute.
 header: phosphotransferase and molecule: glucose Find all topologies that contain the term phosphotransferase in their PTGL HEADER records AND the term glucose in their PTGL MOLECULE records.
 header: phosphotransferase or molecule: glucose Find all topologies that contain the term phosphotransferase in their PTGL HEADER records OR the term glucose in their PTGL MOLECULE records.
 header: phosphotransferase and molecule: glucose and hetname:Zn Find all topologies that contain the term phosphotransferase in their PTGL HEADER records AND the term glucose in their PTGL MOLECULE records AND the term Zn in their PTGL HETNAME records.
 header: phosphotransferase and molecule: glucose and hetname:not Zn Find all topologies that contain the term phosphotransferase in their PTGL HEADER records AND the term glucose in their PTGL MOLECULE records but not the term Zn in their PTGL HETNAME records.
 ((header: phosphotransferase and compound:phosphotransferase) and molecule: not glucose) and compound: not alpha-amylase Find all topologies that contain phosphotransferase in their PTGL HEADER and PTGL COMPOUND records, that do not contain glucose in their PTGL MOLECULE records, and do not contain alpha-amylase in their PTGL COMPOUND records. It is necessary to use ( )'s to maintain the logic of a query that uses more than one "not" clause.
