Abstract

Membrane-free polyribosomes isolated from rat liver cells harbor a casein kinase activity which differentially phosphorylates the various subfractions of total bovine casein. This activity is, in fact, a mixture of two distinct enzyme components which can be separated from each other by molecular filtration. The major component is a S-type enzyme, active exclusively on serine residues of protein substrate, while the other is a TS-type enzyme, active on both threonine and serine residues.
