CC   -!- FUNCTION: Catalyzes the ATP- as well as the pyrophosphate-dependent
CC       phosphorylation of a specific serine residue in HPr, a phosphocarrier
CC       protein of the phosphoenolpyruvate-dependent sugar phosphotransferase
CC       system (PTS). HprK/P also catalyzes the pyrophosphate-producing,
CC       inorganic phosphate-dependent dephosphorylation (phosphorolysis) of
CC       seryl-phosphorylated HPr (P-Ser-HPr). {ECO:0000255|HAMAP-
CC       Rule:MF_01249}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[HPr protein]-L-serine + ATP = [HPr protein]-O-phospho-L-
CC         serine + ADP + H(+); Xref=Rhea:RHEA:46600, Rhea:RHEA-COMP:11602,
CC         Rhea:RHEA-COMP:11603, ChEBI:CHEBI:15378, ChEBI:CHEBI:29999,

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01249};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[HPr protein]-O-phospho-L-serine + H(+) + phosphate = [HPr
CC         protein]-L-serine + diphosphate; Xref=Rhea:RHEA:46604, Rhea:RHEA-

CC         ChEBI:CHEBI:83421; Evidence={ECO:0000255|HAMAP-Rule:MF_01249};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01249};
CC   -!- SUBUNIT: Homohexamer. {ECO:0000255|HAMAP-Rule:MF_01249}.
CC   -!- DOMAIN: The Walker A ATP-binding motif also binds Pi and PPi.
CC       {ECO:0000255|HAMAP-Rule:MF_01249}.
CC   -!- MISCELLANEOUS: Both phosphorylation and phosphorolysis are carried out
CC       by the same active site and suggest a common mechanism for both
CC       reactions. {ECO:0000255|HAMAP-Rule:MF_01249}.
CC   -!- SIMILARITY: Belongs to the HPrK/P family. {ECO:0000255|HAMAP-
CC       Rule:MF_01249}.
