A Ca2+-regulated deAMPylation switch in human and bacterial FIC proteins
In many AMPylating FIC proteins a structurally conserved glutamate represses AMPylation. Here, the authors show that this glutamate supports deAMPylation in Enterococcus faecalis FIC (EfFIC), and that EfFIC switches from AMPylation to deAMPylation by binding Ca2+ at distinct sites.
