Abstract
Protein arginine (Arg) phosphorylation regulates stress responses and virulence in bacteria. With fluorescent activity probes, we show that McsB, a protein Arg kinase, can dephosphorylate phophoarginine (pArg) residues to produce ATP from ADP, implicating the dynamic control of protein pArg levels by the kinase even without the phosphatase.
