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;
CC Evidence={ECO:0000255|HAMAP-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}.
