  • Title: Ribonucleic acid polymerase activity associated with purified calf rotavirus.
    Author: Cohen J.
    Journal: J Gen Virol; 1977 Sep; 36(3):395-402. PubMed ID: 21225.
    Abstract:
    The presence of an RNA-dependent RNA polymerase is demonstrated in purified rotavirus particles. Optimum polymerase activity was found between 45 to 50 degrees C, at pH 8, and in the presence of 10 mM-magnesium ions. The polymerase product was highly sensitive to pancreatic RNase (97%) in low or high salt concentration. The enzyme was activated by EDTA treatment of intact particles or heat shock. The similarities between reovirus, blue-tongue virus and rotavirus polymerases are discussed.
