Figure 6.

Associations of antitoxin super-families. The 20 antitoxin super-families are indicated above the pie chart. Each section of the pie chart represents the relative abundance of toxin sequences belonging to a given super-family associated with antitoxin sequences. Each toxin super-family is represented by a specific color. In (A), antitoxin super-families that are associated with multiple toxin super-families (five or more). In (B), antitoxin super-families that are associated with three or four different toxin super-families. In (C), antitoxin super-families that are associated with AG sequences and another toxin super-family. In (D), antitoxin super-families that are associated with a specific toxin super-family or to AG sequences. Associations occurring at <1% were not considered for clarity.
