Etymologies

phospho- + fructo(se) + kinase.

Examples

  • Fructose bypasses the enzyme phosphofructokinase, which is the rate-limiting enzyme in the glucose metabolism pathway.

    Changing dietary trends and the obesity epidemic | The Blog of Michael R. Eades, M.D.

  • Now, the enzyme that does this conversion to fructose-1,6-bisphosphate is called phosphofructokinase and it is highly and exquisitely regulated by multiple inputs, including other co-factors as well as other modifications.

  • He was having trouble with irreproducible results with phosphofructokinase testing for an E~P mechanism by preincubating the enzyme with ATP32 and chasing it with a mixture of F-6-P and unlabeled ATP.

    Irwin Rose - Autobiography

  • Xu-5-P is generated from glucose metabolism in the hexose monophosphate pathway, which activates phosphofructokinase and promotes the transcription carbohydrate-responsive element-binding protein (ChREBP), thereby increasing the enzymes of lipogenesis, the hexose monophosphate shunt, and glycolysis, all of which are required for lipogenesis.
