Definitions of F Kinase F bisphosphatase

  1. An allosteric enzyme that regulates glycolysis and gluconeogenesis by catalyzing the transfer of a phosphate group from ATP to fructose- 6- phosphate to yield fructose- 2, 6- bisphosphate, an allosteric effector for the other 6- phosphofructokinase, PHOSPHOFRUCTOKINASE- 1. Phosphofructokinase- 2 is bifunctional: the dephosphorylated form is a kinase and the phosphorylated form is a phosphatase that breaks down fructose- 2, 6- bisphosphate to yield fructose- 6- phosphate.
