Viral phosphoesterases (including in CoVs) can restrict antiviral innate immunity




An interesting new study describes the activities of a family of viral enzymes called two-histidine-phosphoesterases (2H-PEs), found in coronaviruses (CoVs) and rotaviruses, as well as a mammalian A-kinase anchoring protein enzyme, AKAP7, that shares the same function. Together called 2’,5’-PEs, these enzymes all break down 2’,5’-oligoadenylate compounds that activate the antiviral enzyme ribonuclease L (RNase L).
