Spleen catalytic properties

An enzyme having catalytic properties and heat stability characteristics similar to those of pancreatic ribonuclease has been purihed from calf spleen and has been found in calf Uver. However, the spleen ribonuclease had a different pH optimum and is separable from pancreatic ribonuclease on a column of cation exchange resin 166). Ribonucleases, with different specificities, have also been described in a variety of animal and plant tissues 157,168), and several ribonucleases of Aspergillus oryzae have been purified and studied 159-161).
