PROPERTIES OF THE CAUSATIVE AGENT OF A @entity1573 TUMOR : IX. THE EFFECT OF AQUEOUS EXTRACTS OF XXXX TUMOR I ON @entity375 NUCLEIC ACID.

@entity13923 @entity3884 @entity5 @entity1573 @entity375
1. Aqueous extracts of @entity1573 @entity5 I cause a disintegration of @entity375 nucleic acid. 2. Two enzyme activities, a polynucleotidase and a phosphatase, are demonstrated. 3. These activities are distinguished by different reactions to an environment of @entity3884 , different optima of @entity3884 ion concentration, and different rates of activity. 4. Adsorption with @entity13923 Type C removes substances inhibiting the polynucleotidase activity. 5. There is a rough proportionality between the polynucleotidase activity and the @entity5 -inducing power of different fractions of extracts of @entity1573 @entity5 I. 6. There is a rough proportionality between the inhibition of polynucleotidase activity and the inhibition of the @entity5 agent. 7. The polynucleotidase activity of @entity1573 @entity5 I is as great as that of spleen, slightly less than that of kidney and liver, but much greater than that of muscle. There are also qualitative differences.
