Protein assassin: Scientists find that the unfolded end of a protein can kill E. coli-like bacteria selectively
When bacteria wage a turf war, some of the combatants have an extra weapon. Certain strains of the bacteria E. coli produce proteins that kill competing E. coli and other like microbes, and researchers from Newcastle Uni ...
