Rapid determination of 16S ribosomal RNA sequences for phylogenetic analyses.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1985
Although the applicability of small subunit ribosomal RNA (16S rRNA) sequences for bacterial classification is now well accepted, the general use of these molecules has been hindered by the technical difficulty of obtaining their sequences. A protocol is

Stochastic kinetics of ribosomes: single motor properties and collective behavior [PDF]

open access: yesPhysical Review E, vol.80, 011908 (2009), 2009
Synthesis of protein molecules in a cell are carried out by ribosomes. A ribosome can be regarded as a molecular motor which utilizes the input chemical energy to move on a messenger RNA (mRNA) track that also serves as a template for the polymerization of the corresponding protein.

Pre-Ribosomal RNA Processing in Human Cells: From Mechanisms to Congenital Diseases

open access: yesBiomolecules, 2018
Ribosomal RNAs, the most abundant cellular RNA species, have evolved as the structural scaffold and the catalytic center of protein synthesis in every living organism.

Unconventional mRNA processing and degradation pathways for the polycistronic yrzI (spyTA) mRNA in Bacillus subtilis

open access: yesFEBS Letters, EarlyView.
The S1025 peptide is the major antidote to the YrzI toxin, which we renamed here as SpyT (Small Peptide YrzI Toxin) and SpyA (Small Peptide YrzI Antitoxin) (1). Degradation of the toxin–antitoxin spyTA mRNA, either by a translation‐dependent cleavage by the endoribonuclease Rae1 (2) or by direct attack by 3′‐exoribonucleases (3), also contributes to ...

Isolation and direct complete nucleotide determination of entire genes. Characterization of a gene coding for 16S ribosomal RNA.

open access: yesNucleic Acids Research, 1989
Using a set of synthetic oligonucleotides homologous to broadly conserved sequences in-vitro amplification via the polymerase chain reaction followed by direct sequencing results in almost complete nucleotide determination of a gene coding for 16S ...

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells

open access: yesMolecular Oncology, EarlyView.
In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (

Modeling of Ribosome Dynamics on a ds-mRNA under an External Load [PDF]

open access: yesJ. 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 ...

Ribosomes and ribosomal RNA as chaperones for folding of proteins

open access: yesFolding and Design, 1997
Provocative recent reports indicate that the large subunits of either prokaryotic or eukaryotic ribosomes have the capacity to promote refolding of denatured enzymes.Salt-washed Escherichia coli ribosomes are shown to promote refolding of denatured rhodanese.

Combined spatially resolved metabolomics and spatial transcriptomics reveal the mechanism of RACK1‐mediated fatty acid synthesis

open access: yesMolecular Oncology, EarlyView.
The authors analyzed the spatial distributions of gene and metabolite profiles in cervical cancer through spatial transcriptomic and spatially resolved metabolomic techniques. Pivotal genes and metabolites within these cases were then identified and validated.

RNA processing: Pocket guides to ribosomal RNA [PDF]

open access: yesCurrent Biology, 1997
The functional role of a recently identified class of small nucleolar (sno) RNAs has been elucidated: the 'box H/ACA' snoRNAs act as guide RNAs, specifying the position of evolutionarily conserved pseudouridines in ribosomal (r)RNA via an rRNA-snoRNA base-pairing interaction that forms a 'pseudouridine pocket'.
