Abstract

1. 1. Guinea-pig liver contained more phosphorylase in the active (phosphorylated) from and less synthase in the active (dephosphorulated) from when compared with rat liver. 2. 2. Activities of cyclic AMP-dependent protein kinase and Ca2+-dependent phosphorylase kinase were the same in rat and guinea-pig livers. 3. 3. Activities of pjosphorylase and synthase phosphatase in the extract and glycogen plus microsomal fracrion of guinea-pig liver were significantly lower than those of rat liver. 4. 4. The existence if inhibitor-1 in the liver of guinea-pig can maintain a lower of type-1 protein phosphatase, especially when inhibitor-1 is phosphorylated by cyclic AMP-dependent protein kinase.
