Properties of a partially purified inhibitor of protein synthesis from the post ribosomal supernatant of six-day-old larvae of Ceratitis capitata

Abstract

Abstract 1. 1. A novel inhibitor of in vitro protein synthesis, was purified from six- day old larvae of the insect Ceratitis capitata. 2. 2. The inhibitor was not a protein, showed no RNase activity, was destroyed by alkali and could be recovered quantitatively in the aqueous phase after phenol extraction. 3. 3. Our findings suggest that the inhibitor is a small RNA.
