Adapting a diet from sugar to meat: double-dealing genes of Streptococcus pyogenes.


Intuitively, paralogues created by gene duplication should retain related functions. However, a study of the two lactose metabolic operons of Streptococcus pyogenes, reported in this issue of Molecular Microbiology, indicates that paralogues might evolve very different functions, in this case changing from a metabolic enzyme to a regulator of virulence… (More)
