✦ Synopsis

Intracellular ribonuclease from the ciliate Tetrahymena pyriform.is GL was purified 10-fold. After preheating for 20 minutes at 100°C of the ribonuclease preparation 80% of its activity was lost. Preheating under the same conditions, however, in the presence of RNA, did not affect the enzyme activity. Between 0°C and 41°C the apparent activation energy was 15,600 cal per deg. per mole,

The utilization of the pool for stable RNA synthesis is poorly affected at the high temperature. It thus appears that the synthesis and processing of ribosomal RNA precu
