The class of ribosomes from Escherichia coli that associate with plant virus RNA in vitro can be separated from the bulk of ribosomes by gradient centrifugation. The relative activity for subsequent incorporation of amino acid into polypeptides directed by the viral RNA in comparison to that directed by polyuridylic acid is the same for that class as for the bulk of ribosomes.
