Molecular modelling of the PFK-2 domain revealed that, instead, it has the same fold as adenylate kinase. This was confirmed by X-ray crystallography.

WebAug 22, 2005 · Purpose: Fructose 2,6-bisphosphate (F2,6BP) is a potent activator of phosphofructokinase, which is a rate-limiting enzyme of glycolysis. The concentration of F2,6BP depends on the activity of the bifunctional enzyme, 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFK-2/FBPase). WebWhy does ATP inhibit Phosphofructose kinase from converting F6P to F-1,6-BP? Apparently ATP allosterically regulates PFK, meaning it inhibits the enzyme by decreasing its affinity for F6P. But I thought ATP is necessary to drive the reaction, so isn't ATP necessary to make the reaction favorable? I'm confused please help! 0 8 comments Add a Comment
The enzyme-catalysed transfer of a phosphoryl group from ATP is an important reaction in a wide variety of biological processes. Phosphofructokinase catalyses the phosphorylation of fructose-6-phosphate to fructose-1,6-bisphosphate, a key regulatory step in the glycolytic pathway. It is allosterically … See more Phosphofructokinase (PFK) is a kinase enzyme that phosphorylates fructose 6-phosphate in glycolysis.
