Protein attributes
| Sequence length | 784 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Catalyzes the third step of glycolysis, the phosphorylation of fructose-6-phosphate (F6P) by ATP to generate fructose-1,6-bisphosphate (FBP) and ADP. |
| 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 | |
| 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. |
| Post-translational modification | GlcNAcylation decreases enzyme activity By similarity. |
| 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. |
