PseudoBase++

PseudoBase is a database containing structural, functional and sequence data related to RNA pseudoknots. It can be reached by its central page at http://pseudobaseplusplus.utep.edu. From here one can retrieve pseudoknot data as well as submit data for pseudoknots that are not yet in the database. There are various alternatives to retrieve data, e.g. in a survey sorted alphabetically on organism names, or sorted on types of RNA molecules or on structural features (such as sizes of paired regions and loops). For each pseudoknot, thirteen items are stored: a PKB-number (a unique number for each pseudoknot entry), definition, organism, abbreviation, category (one of 13 alternatives), keywords, EMBL accession number of the sequence containing this pseudoknot, name of person that submitted the data, support that can be given regarding the reliability of the pseudoknot, reference(s) to relevant paper(s), sizes of each stem, sizes of each loop, the stem positions in the sequence, and finally a so-called bracket view that shows the base-pairs in the pseudoknotted region of the sequence. At the time of writing the database contains over 300 entries with classical H-type pseudoknots as well as more complicated ones.
