title: Partial purification and characterisation of bat liver ribonuclease. Hydrolysis of purine and pyrimidine polynucleotides by bat liver RNase.
abstract: A ribonuclease has been extracted from bat liver and purified. From polyacrylamide gel electrophoresis, it was found that there is only one molecular weight unit in this enzyme and this has a molecular weight of about 28,000. This enzyme was found to hydrolyse both purine and pyrimidine polynucleotides (e.g. polyadenylic acid and polycytidylic acid respectively). Hydrolysis of polyadenylic acid was found to be faster than that of polycytidylic acid.
