Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Catalytic activity	ATP + D-fructose 6-phosphate = ADP + D-fructose 1,6-bisphosphate.
Cofactor	Magnesium.
Enzyme regulation	Allosteric enzyme activated by ADP, AMP, or fructose bisphosphate and inhibited by ATP or citrate.
Pathway	Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 3/4.
Subunit structure	Tetramer. Muscle is M4, liver is L4, and red cell is M3L, M2L2, or ML3. A subunit composition with a higher proportion of platelet type subunits is found in platelets, brain and fibroblasts.
Miscellaneous	In human PFK exists as a system of 3 types of subunits, PFKM (muscle), PFKL (liver) and PFKP (platelet) isoenzymes.
Sequence similarities	Belongs to the phosphofructokinase family. Two domains subfamily.
