The European Small Subunit Ribosomal RNA database

The European database of the Small Subunit (SSU) Ribosomal RNA is a curated database that strives to collect all- information about the primary and se condary structure of completely or nearly-completely sequenced rRNAs, Furth ermore, the database complies additional information such as literature ref erences and taxonomic status of the organism the sequence was derived from. The database can be consulted via the WWW at URL http://rrna.uia.ac.be/ssu /. Through the WWW, sequences can be easily selected either one by one, by taxonomic group, or by a combination of both, and can be retrieved in diffe rent sequence and alignment formats.
