Synthesis of Sendai virus polypeptides by a cell-free extract from wheat germ.

The '18S' RNA population from Sendai virus-infected cells efficiently directed the synthesis of three virus-specific polypeptides P, NP and M, in wheat germ cell-free extracts. In agreement with previous results obtained with a reticulocyte extract, there was little or no production of virus glycopolypeptides. Analyses of tryptic peptides revealed close correspondence between the primary structures of NP and M made in vitro and the authentic virus polypeptides.
