Phosphofructose kinase
WebGlucagon, via cyclic AMP (cAMP) and the cAMP-dependent protein kinase, enhances phosphorylation of pyruvate kinase, phosphofructokinase, and fructose-1,6-bisphosphatase. Phosphorylation of pyruvate kinase results in enzyme inhibition and decreased recycling of phosphoenolpyruvate to pyruvate and enhanced glucose synthesis. Webphosphofructokinase, enzyme that is important in regulating the process of fermentation, by which one molecule of the simple sugar glucose is broken down to two molecules of …

WebPhosphofructokinase (PFK) utilizes ATP to phosphorylate fructose-6-phosphate to fructose-1,6-bisphosphate. As a regulatory enzyme of glycolysis, PFK is negatively inhibited by ATP and citrate and positively regulated by ADP. …. Therefore, additional glycolytic products, such as pyruvate and ATP are not needed. WebMajor conclusions: PFKFB3 has the highest kinase activity to shunt glucose toward glycolysis, whereas PFKFB4 has more FBPase-2 activity, redirecting glucose toward the …
