Role of the constant uridine in binding of yeast tRNAPhe anticodon arm to 30S ribosomes.


Twenty-two anticodon arm analogues were prepared by joining different tetra, penta, and hexaribonucleotides to a nine nucleotide fragment of yeast tRNAPhe with T4 RNA ligase. The oligomer with the same sequence as the anticodon arm of tRNAPhe bind poly U programmed 30S ribosomes with affinity similar to intact tRNAPhe. Analogues with an additional… (More)
