RESUMO

Two zein proteins (Z1 and Z2) represent the majority of the protein synthesized during maize endosperm development. Undegraded membrane-bound polysomes isolated from normal maize synthesized these proteins when incubated in a cell-free protein-synthesizing system from wheat germ. The proteins synthesized in vitro were similar to authentic zein in ethanol solubility and electrophoretic mobility. Zein synthesis was associated with large size classes of membrane bound polysomes in normal maize.
