Abstract
Two different enzymatic activities hydrolyzing 2',3'-cyclic phosphates of purine and pyrimidine ribonucleosides to give 2'- or 3'-ribonucleotides have been detected in plasma membranes of the chick chorioalantois. The enzymes differ in their temperature optima: At lower temperatures, cleavage to the 2'-isomers predominates.
