Presence of a proteinase in polyribosomes of rat liver.
The presence of a proteinase in the composition of the ribosomal proteins of rat liver is demonstrated. The enzyme possesses optimal activity in the zone of pH 7.0-7.2. Soybean trypsin inhibitor and 1-chloro-4-phenyl-3-tosylamido-2-butanone inhibit the enzyme by 50-60%.
