Comparative study of adenosine 3′‐pyrophosphokinase domains of MuF polymorphic toxins

FEBS Open Bio, EarlyView.
With the ultimate goal of understanding the association of toxin‐immunity modules to temperate phages, we characterized toxins from three prophages and examined cross‐protection from immunity proteins. The toxins exhibit adenosine 3′‐pyrophosphokinase activity and are toxic in Escherichia coli.
