Abstract
WE have shown previously that Sendai virus ribonucleoprotein (RNP) particles in the cytoplasm of infected cells are associated with ribosomes in complexes of buoyant density δ = 1.45 g cm−3, and that these take up labelled amino-acids1,2. We now demonstrate that Sendai virus RNP stimulates the incorporation of labelled amino-acids into polypeptides in a cell-free protein synthesizing system, and that this stimulation is 1.5 times greater than that induced by Sendai virus RNA.
