FUNCTION | Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis. |
CATALYTIC ACTIVITY | Reaction=ATP + beta-D-fructose 6-phosphate = ADP + beta-D-fructose 1,6- bisphosphate + H(+); Xref=Rhea:RHEA:16109, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:32966, ChEBI:CHEBI:57634, ChEBI:CHEBI:456216; EC=2.7.1.11; |
COFACTOR | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; |
ACTIVITY REGULATION | Allosterically activated by AMP. |
PATHWAY | Carbohydrate degradation; glycolysis; D-glyceraldehyde 3- phosphate and glycerone phosphate from D-glucose: step 3/4. |
SUBUNIT | Homotetramer. |
case <OC:Kinetoplastea> | |
SUBCELLULAR LOCATION | Glycosome. |
else | |
SUBCELLULAR LOCATION | Cytoplasm. |
end case | |
SIMILARITY | Belongs to the phosphofructokinase type A (PFKA) family. PPi-dependent PFK group II subfamily. Atypical ATP-dependent clade 'X' sub-subfamily. |
