The molecular weight of the RNase was estimated to be 15 kD by gel filtration using Sephadex G100, and the optimum pH and temperature were 4.0 and 55 degrees C, respectively. Catalytic activity was inhibited by Hg2+, Ag+, Fe3+, Co2+ and Zn2+. The enzyme showed guanosine specificity producing only 3'-GMP from yeast RNA.39-50engribonucleaseAspergillusnucleotidesArtigoWOS:000078475500004Acesso restrito70912417428519209424175688206545
