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.
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;
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC   -!- PATHWAY: Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-
CC       phosphate and glycerone phosphate from D-glucose: step 3/4.
CC   -!- SUBUNIT: Homodimer.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- SIMILARITY: Belongs to the phosphofructokinase type A (PFKA) family.
CC       PPi-dependent PFK group II subfamily. Atypical ATP-dependent clade 'X'
CC       sub-subfamily.
