  • Title: Differential inhibition of protein synthesis in reticulocyte lysates and wheat germ extracts by a protein isolated from wheat germ extracts.
    Author: Wu JM.
    Journal: Biochem Int; 1992 Mar; 26(4):669-78. PubMed ID: 1610374.
    Abstract:
    A protein with a molecular mass of 35-37 kDa has been isolated and partially purified from the postribosomal supernatant of wheat germ by ammonium sulfate precipitation (60-90%), Sephadex G-75, and DEAE-cellulose chromatography. It inhibited endogenous protein synthesis in rabbit reticulocyte lysates but had no effect on translation in wheat germ extracts. At low concentrations (0.34-1.36 ng/15 microliter assay), inhibition was limited to initiation of peptide synthesis. At higher concentrations (13.6 ng/15 microliter assay), elongation was also suppressed.
