Abstract
A deletion of five nucleotides was introduced at the 5′ end of the Escherichia coli 16S rRNA gene cloned in an appropriate vector under control of a T7 promoter. The 16S rRNA generated by in vitro transcription could be assembled into 30S subunits. The deletion did not affect the efficiency of translation of natural messengers and the correct selection of the reading frame. However, it reduced the binding of the messengers, which suggests that the 5′ end of 16S rRNA is located on the pathway followed by the messengers on the 30S subunits. The deletion also restricted the stimulation of misreading by streptomycin in a poly(U)-directed system. This is in accord with the proximity of the 5′ end of 16S rRNA to proteins S4, S5 and S12, which are known to be involved in the control of translational accuracy.
