Clustering of bacteria by the triplet composition of 5S RNA [PDF]
ITM Web of ConferencesThe relationship between the structure of nucleotide sequences, the function they encode, and the taxonomy of the host is an important subject of study for molecular biologists and bioinformaticians, as well as specialists in processing big data arrays ...

Modeling of Ribosome Dynamics on a ds-mRNA under an External Load [PDF]
J. Chem. Phys. 145, 025101 (2016), 2016 Protein molecules in cells are synthesized by macromolecular machines called ribosomes. According to recent experimental data, we reduce the complexity of the ribosome and propose a model to express its activity in six main states. Using our model, we study the translation rate in different biological relevant situations in the presence of external ...

Frontiers in Plant Science, 2018 The Brix domain is a conserved domain in several proteins involved in ribosome biogenesis in yeast and animals. In the Arabidopsis genome, six Brix domain-containing proteins are encoded; however, their molecular functions have not been fully ...

In situ quantification of ribosome number by electron tomography
Journal of Microscopy, EarlyView.Abstract Ribosomes, discovered in 1955 by George Palade, were initially described as small cytoplasmic particles preferentially associated with the endoplasmic reticulum (ER). Over the years, extensive research has focused on both the structure and function of ribosomes.

Harnessing promoter elements to enhance gene editing in plants: perspectives and advances
Plant Biotechnology Journal, EarlyView.Summary Genome‐edited plants, endowed with climate‐smart traits, have been promoted as tools for strengthening resilience against climate change. Successful plant gene editing (GE) requires precise regulation of the GE machinery, a process controlled by the promoters, which drives its transcription through interactions with transcription factors (TFs ...

Long non-coding RNAs as a source of new peptides [PDF]
, 2014 Deep transcriptome sequencing has revealed the existence of many transcripts that lack long or conserved open reading frames and which have been termed long non-coding RNAs (lncRNAs). Despite the existence of several well-characterized lncRNAs that play roles in the regulation of gene expression, the vast majority of them do not yet have a known ...

Defective Processing of Cytoplasmic and Chloroplast Ribosomal RNA in the Absence of Arabidopsis DXO1
Plant, Cell &Environment, EarlyView.ABSTRACT Decapping 5′‐3′ exoribonucleases from the DXO/Rai1 family are highly conserved among eukaryotes and exhibit diverse enzymatic activities depending on the organism. The biochemical and structural properties of the plant DXO1 differ from the yeast and animal counterparts, which is reflected in the in vivo functions of this enzyme.

RNA Polymerase III Subunit Mutations in Genetic Diseases
Frontiers in Molecular Biosciences, 2021 RNA polymerase (Pol) III transcribes small untranslated RNAs such as 5S ribosomal RNA, transfer RNAs, and U6 small nuclear RNA. Because of the functions of these RNAs, Pol III transcription is best known for its essential contribution to RNA maturation ...

Probing complex RNA structures by mechanical force [PDF]
European Physical Journal E 12 (2003) 605-615, 2003 RNA secondary structures of increasing complexity are probed combining single molecule stretching experiments and stochastic unfolding/refolding simulations. We find that force-induced unfolding pathways cannot usually be interpretated by solely invoking successive openings of native helices.
