Specifically catalyzes the cleavage of the phosphodiester bond between the 3¢ and 5¢ positions of the ribose moieties in RNA with the formation of oligonucleotides terminating in 2¢,3¢-cyclic phosphate derivs: Roberts et al., Proc. Natl. Acad. Sci. USA 62, 1151 (1969). Reviews: Anfinsen, White, The Enzymes vol. 5, P. D. Boyer et al., Eds.

Properties: Crystals. [a]D25 (per mg N) -0.47° (c = 5). uv max (0.1M KCl soln): 277.5 nm (e 9700). Isoelec pt about pH 8.0. Freely sol in water. Aq solns of cryst ribonuclease are quite stable at temps below 25°. The region of maximum stability is between pH 2 and 4.5. Stable for years stored as refrigerated dry powder or in frozen soln. Aggregates on lyophilization and storage. Shows affinity for glass surfaces. The optimum temp for digestion of yeast ribonucleic acid is 65°. The optimum pH is 7.7. Inhibited by heavy metal ions; by magnesium ions at concns as low as 0.0005M. Competitively inhibited by DNA, the effect of denatured DNA being greater than that of the native nucleic acid. Ribonuclease is precipitated by trichloroacetic acid, and does not diffuse through collodion or cellophane.
Optical Rotation: [a]D25 (per mg N) -0.47° (c = 5)
Absorption maximum: uv max (0.1M KCl soln): 277.5 nm (e 9700)
