Descripción general

Pyruvate Kinase (PK) is a glycolysis enzyme and has four isozymes L, R, M1, and M2. The L isozyme is localized in gluconeogenic tissues, particularly in the liver. Whereas the R and M1 are localized in the adult skeletal muscles, heart, brain and erythrocytes, respectively. M2 is localized in the nucleus of the cells.

Reaction

ATP + pyruvate = ADP + phosphoenolpyruvate

Action

Pyruvate kinase catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to ADP.

This transfer yields one molecule of pyruvate and one molecule of ATP.

Application

Enzymatic determination of ADP, ATP, pyruvate or phsphoenolpyruvate (PEP) when coupled with the related enzymes.
