||Pyruvate kinase is an enzyme involved in glycolysis. It catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to ADP, yielding one molecule of pyruvate and one molecule of ATP.
||1.1mM (ADP); 2.2mM(PEP)
||5.0~10.0 (37°C, 20hr)
||< 60°C (pH8.5, 20min)
||≥ 300U/mg protein
||One unit will convert one micromole of phosphoenolpyruvate to pyruvate per min at pH 7.2 at 30°C.
||The enzyme is reconstituted in 50mM Tris-HCl buffer, pH 8.5 for activity assay.
|Introduction||The protein is a pyruvate kinase that catalyzes the transphosphorylation of phohsphoenolpyruvate into pyruvate and ATP, which is the rate-limiting step of glycolysis. Defects in this enzyme, due to gene mutations or genetic variations, are the common cause of chronic hereditary nonspherocytic hemolytic anemia (CNSHA or HNSHA).|
