Colicin E3 is a highly specific endonuclease that cleaves a single bond in 16S rRNA between A1493 and G1494. This cleavage results in termination of protein synthesis in the cell. In order to determine whether the nucleotide sequence of the target site accounts for colicin E3's specificity, we tested the activity of colicin E3 on short, synthetic double-stranded RNAs that have both identical and modified sequences of the target section of the rRNA. In addition, we tested the activity of the nuclease domain of colicin E3 on ribosomes. The results indicate that the nuclease domain of colicin E3 alone cleaves the short double stranded RNAs non-specifically, while it does not cleave the A1493-G1494 bond in rRNA of purified ribosomes.","abstract_html":"Part IV: Cleavage of 16S rRNA.
