Recent studies have shown that there can be large differences in the stability of double and triple helical nucleic acid complexes, depending on whether RNA or DNA strands are involved. These differences have been attributed to structural differences in the
A 5-methyluridine (m(5)U) residue at position 54 is a conserved feature of bacterial and eukaryotic tRNAs. The methylation of U54 is catalyzed by the tRNA(m5U54)methyltransferase, which in Saccharomyces cerevisiae is encoded by the nonessential TRM2 gene. In this study, we
The last 82 nucleotides of the 6.3 kb genomic RNA of plant turnip yellow mosaic virus (TYMV), the so-called 'tRNA-like' domain, presents functional, structural and primary sequence homologies with canonical tRNAs. In particular, one of the stem-loops resembles the TPsi(pseudouridine)-branch

Ribosomal RNAs (rRNAs) from all kingdoms contain a variety of post-transcriptional modifications and these are typically clustered in the functional centers of the ribosome. The functions of two bases in the 23S rRNA of Escherichia coli that are post-transcriptionally modified

Novel 5'-O-DMT- and MMT-protected 3'-C-methylene-modified thymidine, 5-methyluridine, and 5-methylcytidine H-phosphonates 1-7 with O-methyl, fluoro, hydrogen, and O-(2-methoxyethyl) substituents at the 2'-position have been synthesized by a new effective strategy from the corresponding key intermediates 3'-C-iodomethyl nucleosides and intermediate BTSP, prepared
