Protein

6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 2

Gene
Pfkfb2
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Synthesis and degradation of fructose 2,6-bisphosphate.

Catalytic activityi

Beta-D-fructose 2,6-bisphosphate + H2O = D-fructose 6-phosphate + phosphate.
ATP + D-fructose 6-phosphate = ADP + beta-D-fructose 2,6-bisphosphate.

Enzyme regulationi

The most important regulatory mechanism of these opposing activities is by phosphorylation and dephosphorylation of the enzyme By similarity.
