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). The two antagonistic activities
CC of HprK/P are regulated by several intracellular metabolites, which
CC change their concentration in response to the absence or presence of
CC rapidly metabolisable carbon sources (glucose, fructose, etc.) in the
CC growth medium. Therefore, by controlling the phosphorylation state of
CC HPr, HPrK/P is a sensor enzyme that plays a major role in the
CC regulation of carbon metabolism and sugar transport: it mediates carbon
CC catabolite repression (CCR), and regulates PTS-catalyzed carbohydrate
CC uptake and inducer exclusion. {ECO:0000256|HAMAP-Rule:MF_01249}.
CC -!- CATALYTIC ACTIVITY:

CC -!- DOMAIN: The Walker A ATP-binding motif also binds Pi and PPi.
CC {ECO:0000256|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:0000256|HAMAP-Rule:MF_01249}.
CC -!- SIMILARITY: Belongs to the HPrK/P family.

CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
