Figure 9From: Comprehensive comparative-genomic analysis of Type 2 toxin-antitoxin systems and related mobile stress response systems in prokaryotesGraph of relationships between different families of toxins and antitoxins. Known (black) and predicted (magenta) toxins (red circles) and antitoxins (blue circles) and their operon organizations. Lines connect genes with 5 or more two-component operons found; thickness of a line is proportional to the frequency of the respective operon.Back to article page
