RC STRAIN=PRh5 {ECO:0000313|EMBL:EXU65302.1, RC ECO:0000313|Proteomes:UP000019949}; RA Zhu D., Yang H., Wang Y., Zhang Z., Yan R.; RT "Whole-genome shotgun assembly and analysis of the genome of RT Streptomyces sp. PRh5, a strain for production of geldanamycin, RT nigericin and nocardamine."; RL Submitted (JAN-2014) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Catalyzes the phosphorylation of D-fructose 6-phosphate, CC the first committing step of glycolysis. Uses inorganic phosphate CC (PPi) as phosphoryl donor instead of ATP like common ATP-dependent CC phosphofructokinases (ATP-PFKs), which renders the reaction CC reversible, and can thus function both in glycolysis and CC gluconeogenesis. Consistently, PPi-PFK can replace the enzymes of CC both the forward (ATP-PFK) and reverse (fructose-bisphosphatase CC (FBPase)) reactions. {ECO:0000256|HAMAP-Rule:MF_01976}. CC -!- CATALYTIC ACTIVITY: Diphosphate + D-fructose 6-phosphate = CC phosphate + D-fructose 1,6-bisphosphate. {ECO:0000256|HAMAP- CC Rule:MF_01976}. CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01976, ECO:0000256|SAAS:SAAS00640094}; CC -!- ENZYME REGULATION: Non-allosteric. {ECO:0000256|HAMAP- CC Rule:MF_01976}. 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_01976, ECO:0000256|SAAS:SAAS00640117}. CC -!- SUBUNIT: Homodimer or homotetramer. {ECO:0000256|HAMAP- CC Rule:MF_01976}.

Mixed-substrate PFK group III subfamily. CC {ECO:0000256|HAMAP-Rule:MF_01976}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:EXU65302.1}.
