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_03184}.
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_03184};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC   -!- ACTIVITY REGULATION: Allosterically activated by ADP, AMP, or fructose
CC       2,6-bisphosphate, and allosterically inhibited by ATP or citrate.
CC       {ECO:0000255|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:0000255|HAMAP-Rule:MF_03184}.
CC   -!- SUBUNIT: Homo- and heterotetramers (By similarity). Phosphofructokinase
CC       (PFK) enzyme functions as a tetramer composed of different combinations
CC       of 3 types of subunits, called PFKM (M), PFKL (L) and PFKP (P). The
CC       composition of the PFK tetramer differs according to the tissue type it
CC       is present in. The kinetic and regulatory properties of the tetrameric
CC       enzyme are dependent on the subunit composition, hence can vary across
CC       tissues (Probable). Interacts with ATG4B; promoting phosphorylation of
CC       ATG4B. {ECO:0000255|HAMAP-Rule:MF_03184, ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03184}.
CC   -!- PTM: GlcNAcylation decreases enzyme activity. {ECO:0000250}.
CC   -!- PTM: Phosphorylation at Ser-386 promotes interaction with ATG4B.
CC       {ECO:0000250|UniProtKB:Q01813}.
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:0000255|HAMAP-Rule:MF_03184}.
