In the crude E. coli B cell-free system, mRNA was hydrolyzed by contaminating nuclease activities before significant polymerization of amino acids took place. Ribosomes appeared to be one of the sources of nuclease. A modified high-salt washing procedure was developed to remove nuclease from ribosomes. RNase-free ribosomes thus obtained appeared to be inactive in poly-U-directed phenylalanine incorporation, unless poly-U binding factor was added to the system. R17 RNA could not direct amino acid incorporation in the presence of RNase-free ribosomes because binding of intact R17 RNA to ribosomes did not take place even in the presence of poly-U binding factor.
