TADB 2.0: an updated database of bacterial type II toxin-antitoxin loci.TADB2.0 (http://bioinfo-mml.sjtu.edu.cn/TADB2/) is an updated database that provides comprehensive information about bacterial type II toxin-antitoxin (TA) loci.  With the recent updates, TADB2.0 might provide better support for understanding the important roles of type II TA systems in the prokaryotic life activities.

In addition, the newly developed tool TAfinder combines the homolog searches and the operon structure detection, allowing the prediction for type II TA pairs in bacterial genome sequences.  Additionally, the module TAfinder-Compare allows comparing the presence of the given TA loci across the close relative genomes.
