Names and origin
| Protein names | Recommended name: Pyrophosphate--fructose 6-phosphate 1-phosphotransferase subunit alpha Short name=PFP EC=2.7.1.90 Alternative name(s): 6-phosphofructokinase, pyrophosphate dependent Pyrophosphate-dependent 6-phosphofructose-1-kinase PPi-PFK |
| Organism | Solanum tuberosum (Potato) |
| Taxonomic identifier | 4113 [NCBI] |
| Taxonomic lineage | Eukaryota › Viridiplantae › Streptophyta › Embryophyta › Tracheophyta › Spermatophyta › Magnoliophyta › eudicotyledons › core eudicotyledons › asterids › lamiids › Solanales › Solanaceae › Solanoideae › Solaneae › Solanum |
Protein attributes
| Sequence length | 616 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is not processed. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | The alpha subunit may be involved in the regulation of PFP by Fru-2,6-P. |
| Catalytic activity | Diphosphate + D-fructose 6-phosphate = phosphate + D-fructose 1,6-bisphosphate. |
| Enzyme regulation | Fru-2,6-P is an activator of the plant enzyme. |
| Subunit structure | Tetramer of two alpha and two beta chains. |
| Miscellaneous | The active site might be on the beta subunit. |
| Sequence similarities | Belongs to the pyrophosphate-dependent phosphofructokinase family. |
