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:0000256|HAMAP-Rule:MF_03184}.
CC -!- CATALYTIC ACTIVITY:

CC Evidence={ECO:0000256|ARBA:ARBA00001946,
CC ECO:0000256|HAMAP-Rule:MF_03184};
CC -!- ACTIVITY REGULATION: Allosterically activated by ADP, AMP, or fructose
CC 2,6-bisphosphate, and allosterically inhibited by ATP or citrate.
CC {ECO:0000256|HAMAP-Rule:MF_03184}.
CC -!- PATHWAY: Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-
CC phosphate and glycerone phosphate from D-glucose: step 3/4.
CC {ECO:0000256|ARBA:ARBA00004679, ECO:0000256|HAMAP-Rule:MF_03184,

CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03184}.
CC -!- SIMILARITY: Belongs to the phosphofructokinase type A (PFKA) family.
CC ATP-dependent PFK group I subfamily. Eukaryotic two domain clade "E"
CC sub-subfamily. {ECO:0000256|PIRNR:PIRNR000533}.
CC -!- SIMILARITY: Belongs to the phosphofructokinase type A (PFKA) family.
