phosphofructokinase
(noun)
any of a group of kinase enzymes that convert fructose phosphates to biphosphate
Examples of phosphofructokinase in the following topics:
-
The Energy-Requiring Steps of Glycolysis
- The third step is the phosphorylation of fructose-6-phosphate, catalyzed by the enzyme phosphofructokinase.
- In this pathway, phosphofructokinase is a rate-limiting enzyme.
-
Control of Catabolic Pathways
- The product of the hexokinase reaction is glucose-6-phosphate, which accumulates when a later enzyme, phosphofructokinase, is inhibited.
- Phosphofructokinase is the main enzyme controlled in glycolysis.
