Cell-Free Synthesis of Rice Prolamin

Abstract
Polyadenylated RNA was isolated from the protein-body rich fraction of developing rice (Oryza sativa. L) seeds. In a wheat germ cell-free system, the isolated polyadenylated RNA produced polypeptides with the same solubility as prolamin subunits. The electrophoretic mobility of the polypeptides suggested the presence of a signal peptide.
