Control of ribosome traffic by position-dependent choice of synonymous codons [PDF]
Phys. Biol. 10 (2013) 056011, 2013 Messenger RNA encodes a sequence of amino acids by using codons. For most amino acids there are multiple synonymous codons that can encode the amino acid. The translation speed can vary from one codon to another, thus there is room for changing the ribosome speed while keeping the amino acid sequence and hence the resulting protein.

A systematic search for discriminating sites in the 16S ribosomal RNA gene [PDF]
Microbial Informatics and Experimentation, 2014 The 16S rRNA is by far the most common genomic marker used for prokaryotic classification, and has been used extensively in metagenomic studies over recent years. Along the 16S gene there are regions with more or less variation across the kingdom of bacteria.

Zdravniški Vestnik, 2008 BACKGROUND The correct identification of bacterial isolates is paramount for the correct diagnosis andtreatment of patients. The standard approach for bacterial identification relies on phenotypic tests, which are often time-consuming and unreliable when

Phylogenetically informed Bayesian truncated copula graphical models for microbial association networks [PDF]
arXiv, 2021 Microorganisms play a critical role in host health. The advancement of high-throughput sequencing technology provides opportunities for a deeper understanding of microbial interactions. However, due to the limitations of 16S ribosomal RNA sequencing, microbiome data are zero-inflated, and a quantitative comparison of microbial abundances cannot be made

Distribution of dwell times of a ribosome: effects of infidelity, kinetic proofreading and ribosome crowding [PDF]
Physical Biology, 8 (2011) 026005, 2010 Ribosome is a molecular machine that polymerizes a protein where the sequence of the amino acid residues, the monomers of the protein, is dictated by the sequence of codons (triplets of nucleotides) on a messenger RNA (mRNA) that serves as the template. The ribosome is a molecular motor that utilizes the template mRNA strand also as the track. Thus, in

Alternative conformations in Escherichia coli 16S ribosomal RNA. [PDF]
Proceedings of the National Academy of Sciences, 1985 Partially denatured 16S rRNA from 30S ribosomes shows features of secondary structure in electron microscopy that correspond to the well accepted secondary structure model derived from chemical modification and phylogenetic data. However, a very different conformation is seen in precursor 16S rRNA sequences contained within 30S pre-rRNA transcripts ...

Aneurysm Infection Caused by Desulfovibrio desulfuricans
Emerging Infectious Diseases, 2023 An 84-year-old man in Japan who had undergone endovascular aortic repair 9 years earlier had an infected aneurysm develop. We detected Desulfovibrio desulfuricans MB at the site.

SEARCH_16S: A new algorithm for identifying 16S ribosomal RNA genes in contigs and chromosomes
bioRxiv, 2017 SEARCH_16S is a new algorithm that annotates 16S ribosomal RNA genes in microbial genomes and metagenomic sequences. Word counting is used to identify candidate segments, then conserved motifs are used to identify homologous loci close to the gene ...

In vitro methylation of Escherichia coli 16S ribosomal RNA and 30S ribosomes. [PDF]
Proceedings of the National Academy of Sciences, 1989 Treatment of synthetic 30S particles lacking all of the normally methylated nucleotides with S-adenosyl-[3H]methionine and either an S100 or ribosomal high salt wash extract resulted in ribosome-dependent incorporation of [3H]methyl groups into trichloroacetic acid-insoluble material. No incorporation was observed when naturally methylated isolated 30S
