Evidence for cyclic AMP-dependent protein kinase activity in isolated guinea pig and rat liver mitochondria.

Abstract

Purified preparations of guinea pig and rat liver mitochondria contain considerable latent cAMP-dependent protein kinase activity that is revealed by treatment with 1% Triton X-100. The solubilized kinase was partly purified by DEAE-cellulose chromatography. It accepts protein in the washed Triton-extracted mitochondria as substrate.
