Search help

Enter any number of search terms. Items that will be searched include SCOP titles, keywords from PDB entries, gene and species names, SCOP comments, and various SCOP identifiers (sunid, sid, sccs). If you enter multiple terms, results containing any of the terms are returned (although results matching several terms rank higher). If you put a '+' immediately before a term, it must be present in the results. If you put a '-' before a term, results matching the term will NOT be returned. If you put a '~' before a term, results matching the term will be downweighted relative to those that don''t. Multi-word terms can be surrounded by double quotes. You can also group terms in parentheses.

If you are searching for the structural consequence of a genetic variant, check out our advanced variant search page.

The search engine we use is MySQL's full text searching. More info on operators you can use is here.


  • searching for 1jmc will return matches to the PDB entry 1JMC.
  • searching for Desulfovibrio vulgaris Hildenborough will match various domains from D. vulgaris Hildenborough, but will also match other D. vulgaris domains with lower priority.
  • searching for +Desulfovibrio +vulgaris +Hildenborough will ONLY match domains from D. vulgaris Hildenborough.
  • searching for d1dlya_ will immediately redirect you to the page for the domain d1dlya_, since there is only one result.
  • searching for 32145 will find many things, including folds with beta-strand order 32145, but:
  • searching for "sunid=32145" will find only the domain d1eloa2, which has sunid 32145.
  • searching for NC_000002.12:g.97734708C>T will show the structural consequence of the variant NC_000002.12:g.97734708C>T.
  • You can specify particular types of identifiers, e.g., "sid=d1XXX_" or "sccs:x.n.n" (either : or = will work) with SCOP sid, SCOP sunid, SCOP sccs, Uniprot, Pfam, and PDB identifiers.
  • If you want results from a particular level in SCOP (e.g., family), try adding a search term like "+Family"
  • The special keywords newcf, newsf, and newfa will retrieve all new Folds, Superfamilies, or Families, respectively, in a release.
