CC   -!- FUNCTION: Catalyzes the specific phosphorylation of arginine residues
CC       in proteins. {ECO:0000255|HAMAP-Rule:MF_00602}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-arginyl-[protein] = ADP + H(+) + N(omega)-phospho-L-
CC         arginyl-[protein]; Xref=Rhea:RHEA:43384, Rhea:RHEA-COMP:10532,
CC         Rhea:RHEA-COMP:10533, ChEBI:CHEBI:15378, ChEBI:CHEBI:29965,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:83226, ChEBI:CHEBI:456216;
CC         EC=2.7.14.1; Evidence={ECO:0000255|HAMAP-Rule:MF_00602};
CC   -!- ACTIVITY REGULATION: Appears to be allosterically activated by the
CC       binding of pArg-containing polypeptides to the pArg-binding pocket
CC       localized in the C-terminal domain of McsB. {ECO:0000255|HAMAP-
CC       Rule:MF_00602}.
CC   -!- SIMILARITY: Belongs to the ATP:guanido phosphotransferase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00602}.
