title: The tmRNA website.
abstract: tmRNA (10Sa RNA) has a central role in trans -translation, in which a peptide tag encoded in tmRNA is added to the abnormally short protein product of a broken mRNA, as a signal for proteolysis of the entire tagged protein. The tmRNA website was established in 1997 as a resource for phylogenetic considerations of tmRNA structure and function. Since then, three partial tmRNA sequences have been completed, and sequences from 13 more species have been identified. Forty-six species from 10 bacterial phyla and chloroplasts are now represented in the database. Provisional sequence alignments and predicted proteolysis tag sequences are provided, as well as a literature review and a guide to searching for new tmRNA sequences. The tmRNA website is accessible via WWW at a new URL: http://sunflower.bio.indiana.edu/kwilliam/tmRNA /home.html
