ABSTRACT
The effect of cloacin DF13 cleavage on several functional properties of the ribosome has been studied in a translational system in vitro. Cleaved ribosomes synthesize relatively shorter polypeptide chains on synthetic and natural templates. Their translational specificity is, however, unchanged as judged by the read-out of MS2 RNA. Here, cleaved as well as control ribosomes start translation only on the coat cistron of the phage RNA. Cloacin cleavage of ribosomes increases their fidelity of translation. Differential inhibition of translation of synthetic and natural template was not observed.
