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 Evidence={ECO:0000255|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: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}.
