RL Submitted (JUN-2013) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the phosphorylation of D-fructose 6-phosphate, the
CC first committing step of glycolysis. Uses inorganic phosphate (PPi) as
CC phosphoryl donor instead of ATP like common ATP-dependent
CC phosphofructokinases (ATP-PFKs), which renders the reaction reversible,
CC and can thus function both in glycolysis and gluconeogenesis.
CC Consistently, PPi-PFK can replace the enzymes of both the forward (ATP-
CC PFK) and reverse (fructose-bisphosphatase (FBPase)) reactions.
CC {ECO:0000256|HAMAP-Rule:MF_01978}.
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 -!- ACTIVITY REGULATION: Non-allosteric. {ECO:0000256|HAMAP-Rule:MF_01978}.
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_01978}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01978}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01978}.
CC -!- SIMILARITY: Belongs to the phosphofructokinase type A (PFKA) family.
CC PPi-dependent PFK group II subfamily. Clade 'B2' sub-subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_01978}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01978}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
