(18) In this report, we have compared homogeneous yeast (Saccharomyces cerevisiae) pyruvate kinase to enzyme from cell-free extracts in several different ways: 1) isoelectric focusing of cell-free extracts indicates one peak of pyruvate kinase activity whose isoelectric point is the same as that of the pure enzyme; 2) antibody prepared to the pure enzyme produces a single, fused precipitin line against enzyme in the cell-free extract and pure enzyme; 3) immunoelectrophoresis of cell-free extract produces one precipitin arc which has the same mobility as that of the pure enzyme; and 4) immunoprecipitation of the pure enzyme from cell-free extract with subsequent solubilization in 1% sodium dodecyl sulfate and electrophoresis on sodium dodecyl sulfate-polyacrylamide gels produces a single protein band attributable to pyruvate kinase which co-migrates with the purified enzyme.
