Boris Zinshteyn et al.

Nucleic acids research, 47(1), 43-55 (2018-11-27)

Chemical probing methods are crucial to our understanding of the structure and function of RNA molecules. The majority of chemical methods used to probe RNA structure report on Watson-Crick pairing, but tertiary structure parameters such as solvent accessibility can provide

Supersized Ribosomal RNA Expansion Segments in Asgard Archaea.

Petar I Penev et al.

Genome biology and evolution, 12(10), 1694-1710 (2020-08-14)

The ribosome's common core, comprised of ribosomal RNA (rRNA) and universal ribosomal proteins, connects all life back to a common ancestor and serves as a window to relationships among organisms. The rRNA of the common core is similar to rRNA

Synthesis, 433-433 (1993)

Quantitative evaluation of the mechanism of electroreduction of benzoyl cyanides.

Norma A Macías-Ruvalcaba et al.

The Journal of organic chemistry, 72(2), 589-594 (2007-01-16)

The mechanism of reduction of benzoyl cyanide, 6, p-methoxybenzoyl cyanide, 7, and p-chlorobenzoyl cyanide, 8, has been studied in acetonitrile (6 and 7), N,N-dimethylformamide (6), and acetonitrile containing water (all three compounds). The reaction proceeds by initial reduction to form

The RNA of Maize Chlorotic Mottle Virus, an Obligatory Component of Maize Lethal Necrosis Disease, Is Translated via a Variant Panicum Mosaic Virus-Like Cap-Independent Translation Element.

Elizabeth J Carino et al.

Journal of virology, 94(22) (2020-08-28)

Maize chlorotic mottle virus (MCMV) combines with a potyvirus in maize lethal necrosis disease (MLND), a serious emerging disease worldwide. To inform resistance strategies, we characterized the translation initiation mechanism of MCMV. We report that MCMV RNA contains a cap-independent

Biosynthesis of benzoylformic acid from benzoyl cyanide by a newly isolated Rhodococcus sp. CCZU10-1 in toluene-water biphasic system.

Yu-Cai He et al.

Bioresource technology, 115, 88-95 (2011-10-29)

Benzoylformic acid was synthesized from the hydrolysis of benzoyl cyanide by a newly isolated Rhodococcus sp. CCZU10-1. In this study, an aqueous-toluene biphasic system was developed for highly efficient production of benzoylformic acid from the hydrolysis of benzoyl cyanide. In

Design and application of a biphasic system that enhances productivity of Daucus carota-catalyzed asymmetric reduction.

Weisi Xiong et al.

Biotechnology letters, 37(8), 1703-1709 (2015-04-22)

To develop a biphasic system for use in plant tissue-mediated biotransformations to overcome the low water solubilities of substrates and inhibitory effects of products. Commonly-used organic solvents and ionic liquid were assayed using the biphasic system to reduce water-insoluble benzoyl

A Stem-Loop Structure in Potato Leafroll Virus Open Reading Frame 5 (ORF5) Is Essential for Readthrough Translation of the Coat Protein ORF Stop Codon 700 Bases Upstream.

Yi Xu et al.

Journal of virology, 92(11) (2018-03-09)

Translational readthrough of the stop codon of the capsid protein (CP) open reading frame (ORF) is used by members of the Luteoviridae to produce their minor capsid protein as a readthrough protein (RTP). The elements regulating RTP expression are not

Chemical footprinting reveals conformational changes of 18S and 28S rRNAs at different steps of translation termination on the human ribosome.

Konstantin N Bulygin et al.

RNA (New York, N.Y.), 22(2), 278-289 (2015-12-15)

Translation termination in eukaryotes is mediated by release factors: eRF1, which is responsible for stop codon recognition and peptidyl-tRNA hydrolysis, and GTPase eRF3, which stimulates peptide release. Here, we have utilized ribose-specific probes to investigate accessibility of rRNA backbone in
