Updating the 97% identity threshold for 16S ribosomal RNA OTUs [PDF]
Bioinformatics, 2017 AbstractThe 16S ribosomal RNA (rRNA) gene is widely used to survey microbial communities. Sequences are often clustered into Operational Taxonomic Units (OTUs) as proxies for species. The canonical clustering threshold is 97% identity, which was proposed in 1994 when few 16S rRNA sequences were available, motivating a reassessment on current data ...

Parasites & Vectors, 2020 Background Molecular advances have accelerated our understanding of nematode systematics and taxonomy. However, comparative analyzes between various genetic markers have led to discrepancies in nematode phylogenies.

Location of Ribosomal Protein Binding Sites on 16S Ribosomal RNA [PDF]
Proceedings of the National Academy of Sciences, 1972 The distribution of ribosomal protein binding sites on the 16S ribosomal RNA molecule has been analyzed by limited ribonuclease hydrolysis of RNA-protein complexes, as well as by the interaction of individual proteins with RNA fragments purified from partial enzymatic digests. Of the six 30S subunit proteins known to interact directly with

Functional Modification of 16S Ribosomal RNA by Kethoxal [PDF]
Proceedings of the National Academy of Sciences, 1972 Kethoxal reacts with 30S ribosomal subunits to give totally inactive particles, as measured by in vitro protein synthesis. It is postulated that functional modification occurs at the binding site for transfer RNA since ( a ) loss of specific binding of transfer RNA, but not binding of ...

Taxonomy of anaerobic digestion microbiome reveals biases associated with the applied high throughput sequencing strategies [PDF]
, 2018 In the past few years, many studies investigated the anaerobic digestion microbiome by means of 16S rRNA amplicon sequencing. Results obtained from these studies were compared to each other without taking into consideration the followed procedure for ...

Ribosomal Protein S12 Hastens Nucleation of Co-Transcriptional Ribosome Assembly
Biomolecules, 2023 Ribosomal subunits begin assembly during transcription of the ribosomal RNA (rRNA), when the rRNA begins to fold and associate with ribosomal proteins (RPs). In bacteria, the first steps of ribosome assembly depend upon recognition of the properly folded

Enrichment and characterization of a bacteria consortium capable of heterotrophic nitrification and aerobic denitrification at low temperature [PDF]
, 2013 Nitrogen removal in wastewater treatment plants is usually severely inhibited under cold temperature. The present study proposes bioaugmentation using psychrotolerant heterotrophic nitrification-aerobic denitrification consortium to enhance nitrogen ...

Action spectra for UV-light induced RNA–RNA crosslinking in 16S ribosomal RNA in the ribosome [PDF]
Photochemical & Photobiological Sciences, 2003 UV irradiation induces intramolecular crosslinks in ribosomal RNA in the ribosome. These crosslinks occur between nucleotides distant in primary sequence and they are specific, limited in number and have crosslinking efficiencies sufficient to allow their use in monitoring conformational changes.
