T1TAdb currently contains 1894 TA loci from 493 bacterial strains (view organism list) and 25 TA families (view family list):

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.
For a complete release history, see the release history tab.

last update: September 15, 2021

T1TAdb provides data on:
  • genomic locations of the TA loci, including full genome views and flanking genes
  • 2D structure predictions of toxin mRNAs and antitoxin sRNAs
  • 2D predictions and hydrophobicity plots of toxin peptides
  • sequences of all features, including promoter and mRNA-asRNA interaction regions
as well as tools for:
  • advanced keyword searches by feature name, organism name, or locus accession
  • sequence similarity search
  • multiple sequence alignment
