Comments [?]

Function Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis.
Catalytic activity RHEA:16109: ATP + beta-D-fructose 6-phosphate = ADP + beta-D-fructose 1,6-bisphosphate + H(+)
EC 2.7.1.11
Cofactor Mg(2+)
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.
