Toxin–antitoxin systems shows variability among Mycobacterium tuberculosis lineages

The toxin–antitoxin (TA) systems are operons involved in the formation of persistent cells and in stress situations in microorganism. TA systems are widely distributed in Mycobacterium tuberculosis (MTB). The objective of this study was to determine the distribution and variability of protein sequences of TA systems in seven MTB lineages. Protein prediction on 73 genomes of different lineage was made using Prodigal, and profile hidden Markov...
