• Release 7
    December 5, 2022: RNA alignment options now include the possibility to add (or remove) flanking sequences and to perform pure (i.e., structure-independent) sequence alignment, in addition to structural alignment.

  • Release 6
    June 20, 2022: The JSAV sequence alignment viewer has been included in replacement of the discontinued MSAViewer tool.

  • Release 5
    July 11, 2021: a number of updates and additions have been made, including a recently reported family (TimP/TimR) and information about leader/regulatory ORFs. Loci annotated in multiple genome versions of an organism have been remapped to the most recent genome version.

  • Release 4
    July 29, 2020: MAJOR UPDATE: a number of loci have been re-predicted and corrected, in particular with respect to the location and sequence of the antitoxin asRNA

  • Release 3
    July 17, 2020: secondary structures of peptides have been re-predicted using the latest version of PSIPRED (4.02) run with PSI-BLAST against UniRef90 database

  • Release 2
    June 27, 2020: MAJOR UPDATE: a large number of loci have been re-predicted and corrected, in particular with respect to the location and sequence of the antitoxin asRNA
    Note: re-predicted loci have been given new locus IDs. Here is a file giving the correspondence between current and previous IDs for updated loci.

  • Release 1
    January 9, 2019: T1TAdb, the first type I toxin-antitoxin database!
