the changes in the kinetic properties of hepatic pyruvate kinase which follow treating the perfused rat liver with glucagon or cyclic amp are consistent with the changes observed in the enzyme properties upon phosphorylation in vitro by a clyclic amp-stimulated protein kinase ( ljungstrom , o. , hjelmquist , g. and engstrom , l. ( 1974 ) biochim . biophys . acta 358 , 289 -- 298 ) .
