Replacement of RNA hairpins byin vitroselected tetranucleotides

Year: 1993

Type: article

Abstract: An in vitro selection method based on the autolytic cleavage of yeast tRNA(Phe) by Pb2+ was applied to obtain tRNA derivatives with the anticodon hairpin replaced by four single-stranded nucleotides. Based on the rates of the site-specific cleavage by Pb2+ and the presence of a specific UV-induced crosslink, certain tetranucleotide sequences allow proper folding of the rest of the tRNA molecule, whereas others do not. One such successful tetramer sequence was also used to replace the acceptor stem of yeast tRNA(Phe) and the anticodon hairpin of E.coli tRNA(Phe) without disrupting folding. These experiments suggest that certain tetramers may be able to replace structurally nonessential hairpins in any RNA.
