CC -!- FUNCTION: Catalyzes the specific phosphorylation of arginine residues
CC in a large number of proteins. Is part of the bacterial stress response
CC system. Protein arginine phosphorylation has a physiologically
CC important role and is involved in the regulation of many critical
CC cellular processes, such as protein homeostasis, motility, competence,
CC and stringent and stress responses, by regulating gene expression and
CC protein activity. {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}.
