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.
Molecular Weight 237 kDa (as a tetramer of four equal subunits 57 kDa)
Reaction ATP + pyruvate = ADP + phosphoenolpyruvate
