CC   -!- FUNCTION: Catalyzes the phosphorylation of D-fructose 6-phosphate
CC       to 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
CC         1,6-bisphosphate + H(+); Xref=Rhea:RHEA:16109,

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_03184};
CC   -!- ACTIVITY REGULATION: Allosterically activated by ADP, AMP, or
CC       fructose 2,6-bisphosphate, and allosterically inhibited by ATP or
CC       citrate. {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).
CC       Phosphofructokinase (PFK) enzyme functions as a tetramer composed
CC       of different combinations of 3 types of subunits, called PFKM (M),
CC       PFKL (L) and PFKP (P). The composition of the PFK tetramer differs
CC       according to the tissue type it is present in. The kinetic and
CC       regulatory properties of the tetrameric enzyme are dependent on
CC       the subunit composition, hence can vary across tissues (Probable).
CC       Interacts (via C-terminus) with HK1 (via N-terminal spermatogenic
CC       cell-specific region) (By similarity).

CC       ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03184}.
CC   -!- PTM: GlcNAcylation decreases enzyme activity. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the phosphofructokinase type A (PFKA)
CC       family. ATP-dependent PFK group I subfamily. Eukaryotic two domain
CC       clade "E" sub-subfamily. {ECO:0000255|HAMAP-Rule:MF_03184}.
