Purification and properties of three cytosolic ribonucleases of mouse liver.
The ribonucleolytic activity of mouse liver cytosol is due to at least three different enzymes, whose purification is reported. Two of these enzymes, an alkaline and a neutral RNase, have specificities practically identical with that of pancreatic RNase. The third enzyme, an acid RNase, is highly specific for NpU bonds where N is A, G or C and also cleaves ApG bonds provided they are part of a GpApG sequence and preferentially a GpApGpA repeat.
