6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 4; 6PF-2-K/fru-2,6-P2ase 4; PFK/FBPase 4; 6PF-2-K/fru-2,6-P2ase testis-type isozyme; includes: 6-phosphofructo-2-kinase; fructose-2,6-bisphosphatase (PFKFB4)

Function

• dual function phosphomonoesterase
• synthesis & degradation of fructose-2,6-bisphosphate
• regulation by phosphorylation & dephosphorylation (putative)

ATP + D-fructose-6-phosphate -> ADP + D-fructose-2,6-bisphosphate

D-fructose-2,6-bisphosphate + H2O -> D-fructose-6-phosphate + phosphate

Structure

• homodimer (putative)
• in the C-terminal section; belongs to the phosphoglycerate mutase family

More general terms

• 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase
