Toxin–antitoxin loci are highly abundant in free-living but lost from host-associated prokaryotes
Prokaryotic chromosomes code for toxin–antitoxin (TA) loci, often in multiple copies. In E.coli, experimental evidence indicates that TA loci are stress-response elements that help cells survive unfavorable growth conditions. The first gene in a TA operon codes for an antitoxin that combines with an...
