Abstract

Acid RNAases of ST were resolved into one minor and two major peaks by Sulphopropyl Sephadex chromatography. The same three peaks were obtained from exponentially growing cells and from heat-synchronized cells. The two major RNAases (peaks 2 and 3) were also separated by polyacrylamide gel electrophoresis at pH 4·5 and 8·3. The stepwise increase in total RNAase activity during synchronous growth was primarily caused by a large and preferential increase in the activity of the peak 3 RNAase during the first hour after the heat shock.
