Previous studies suggest that the mechanism of action of the ribosome in translation involves crucial transfer RNA (tRNA)-ribosomal RNA (rRNA) interactions. Here, a selection scheme was developed to identify bases in 16S rRNA that are essential for tRNA binding to the P site of the small (30S) ribosomal subunit. Modification of the N-1 and N-2 positions of(More)
Aminoglycoside inhibitors of translation have been shown previously to inhibit in vitro self-splicing by group I introns. Chemical probing of the phage T4-derived sunY intron shows that neomycin, streptomycin, and related antibiotics protected the N-7 position of G96, a universally conserved guanine in the binding site for the guanosine cofactor in the(More)
