CC   -!- FUNCTION: Catalyzes the phosphorylation of D-fructose 6-phosphate to
CC       fructose 1,6-bisphosphate by ATP, the first committing step of
CC       glycolysis. {ECO:0000255|HAMAP-Rule:MF_00339}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + beta-D-fructose 6-phosphate = ADP + beta-D-fructose 1,6-
CC         bisphosphate + H(+); Xref=Rhea:RHEA:16109, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:32966, ChEBI:CHEBI:57634,
CC         ChEBI:CHEBI:456216; EC=2.7.1.11; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00339};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00339};
CC   -!- ACTIVITY REGULATION: Allosterically activated by ADP and other
CC       diphosphonucleosides, and allosterically inhibited by
CC       phosphoenolpyruvate. {ECO:0000255|HAMAP-Rule:MF_00339}.
CC   -!- PATHWAY: Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-
CC       phosphate and glycerone phosphate from D-glucose: step 3/4.
CC       {ECO:0000255|HAMAP-Rule:MF_00339}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00339}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00339}.
CC   -!- SIMILARITY: Belongs to the phosphofructokinase type A (PFKA) family.
CC       ATP-dependent PFK group I subfamily. Prokaryotic clade 'B1' sub-
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_00339}.
