WebNov 2, 2024 · Like glycolysis, there is an additional regulation here by the bifunctional enzyme phosphofructokinase 2 (PFK2)/fructose 2,6-bisphosphatase (figure 4.1). This bifunctional enzyme functions as a kinase in the fed state (PFK2) and generates fructose 2,6-bisphosphate that allosterically activates PFK1. http://pressbooks-dev.oer.hawaii.edu/biology/chapter/glycolysis/
