Pyruvate kinase

• Cat.No.: PKLR-1544

Specification

• Cat. No.: PKLR-1544
• Description: 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.
• Source: Microorganism
• Predicted MolecularMass: 68kDa
• Isoelectic point: 5.2
• Michaelis constant: 1.1mM (ADP); 2.2mM(PEP)
• Optimum pH: 7.5
• Optimum temperature: 80°C
• pH Stability: 5.0~10.0 (37°C, 20hr)
• Thermal Stability: < 60°C (pH8.5, 20min)
• Inhibitors: Ag+, Hg2+
• Specific Activity: ≥ 300U/mg protein
• Unit definition: One unit will convert one micromole of phosphoenolpyruvate to pyruvate per min at pH 7.2 at 30°C.
• Storage: -20°C
• PreparationInstructions: 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).
