    “…A bioinformatic covariation analysis of a collection of 119 novel variants of the antigenomic, self-cleaving hepatitis delta virus (HDV) RNA motif supported the formation of all of the Watson–Crick base pairs (bp) of the catalytic centre except the C19–G81 pair located at the bottom of the P2 stem. …”

    “…In this study we demonstrate, using genetic and biochemical analyses, that in Escherichia coli, TnaC residue I19 and 23S rRNA nucleotide A2058 are essential for the ribosome’s ability to sense free L-Trp. …”

    “…Here, we investigated the 3′ modification of silencing-related small RNAs in Nicotiana benthamiana plants infected with viruses expressing RNA silencing suppressors, the p19 protein of Carnation Italian ringspot virus (CIRV) and HC-Pro of Tobacco etch virus (TEV). …”

    “…The results show that the base A73; the core structure of tRNA formed by the tertiary interactions U8–A14, G18–U55 and G19–C56; and the orientation of the variable arm are critical elements for tRNA(Leu) aminoacylation. …”

    “…It is known that dsRNAs ≥25 bp are processed by Dicer to create classic 19-bp siRNAs with 3′-end overhangs. We demonstrate that the presence of minimal modification configurations on longer RNA duplexes can block Dicer processing and result in the loading of the full-length guide strand into RISC with resultant mRNA cleavage at a defined site. …”
