Bacteria reinvent their weapons through selection, chance and gene swapping

Many of the most potent antibiotics originate from bacteria. A large proportion belong to a class of compounds known as nonribosomal peptides (NRP). They are produced by large bacterial enzyme machineries—the nonribosomal ...
