title: [Ribonuclease activity of the "myofibrillar" fraction of normal and autolyzed muscle tissue].
abstract: The separation in a sucrose gradient of the "myofibrillar" fraction of normal and autolysed muscle tissue gave 4 components. During the post-mortem destruction of the tissue there was observed a slight decrease of the "myofibrillar" fraction yield and also certain changes in the distribution of protein between different components. Under the selected conditions the RNA-ase activity was found in all 4 components. During the course of autolysis the enzymatic activity increased in the whole "myofibrillar" fraction, as well as in the lysosomal-mitochondrial components of "myofibrillae".
