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_01976}.
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         Rule:MF_01976};
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_01976}.
CC   -!- SUBUNIT: Homodimer or homotetramer. {ECO:0000255|HAMAP-Rule:MF_01976}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01976}.
CC   -!- SIMILARITY: Belongs to the phosphofructokinase type A (PFKA) family.
CC       Mixed-substrate PFK group III subfamily. {ECO:0000255|HAMAP-
CC       Rule:MF_01976}.
