CC -!- FUNCTION: Catalytic subunit of pyrophosphate--fructose 6-phosphate 1-
CC phosphotransferase. Catalyzes the phosphorylation of D-fructose 6-
CC phosphate, the first committing step of glycolysis. Uses inorganic
CC phosphate (PPi) as phosphoryl donor instead of ATP like common ATP-
CC dependent phosphofructokinases (ATP-PFKs), which renders the reaction
CC reversible, and can thus function both in glycolysis and
CC gluconeogenesis. {ECO:0000256|HAMAP-Rule:MF_03185}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=beta-D-fructose 6-phosphate + diphosphate = beta-D-fructose
CC 1,6-bisphosphate + H(+) + phosphate; Xref=Rhea:RHEA:13613,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:32966, ChEBI:CHEBI:33019,

CC Evidence={ECO:0000256|ARBA:ARBA00000628, ECO:0000256|HAMAP-
CC Rule:MF_03185};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|ARBA:ARBA00001946,
CC ECO:0000256|HAMAP-Rule:MF_03185};
CC -!- ACTIVITY REGULATION: Allosterically activated by fructose 2,6-
CC bisphosphate. {ECO:0000256|HAMAP-Rule:MF_03185}.
CC -!- PATHWAY: Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-
CC phosphate and glycerone phosphate from D-glucose: step 3/4.
CC {ECO:0000256|HAMAP-Rule:MF_03185}.
CC -!- SUBUNIT: Tetramer of two alpha (regulatory) and two beta (catalytic)
CC chains. {ECO:0000256|HAMAP-Rule:MF_03185}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03185}.
CC -!- SIMILARITY: Belongs to the phosphofructokinase type A (PFKA) family.
CC PPi-dependent PFK group II subfamily. Clade 'Long' sub-subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_03185}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_03185}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
