The structure of a methylated tetraloop in 16S ribosomal RNA [PDF]
Structure, 1998 Ribosomal RNAs contain many modified nucleotides. The functions of these nucleotides are poorly understood and few of them are strongly conserved. The final stem loop in 16S-like rRNAs is an exception in both regards. In both prokaryotes and eukaryotes, the tetranucleotide loop that caps the 3'-terminal stem contains two N6, N6-dimethyladenosine ...

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.

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 ...

Role of 16‐S RNA in Ribosome Messenger Recognition [PDF]
European Journal of Biochemistry, 1980 The deoxyoctanucleotide (5′‐3′)d(A‐A‐G‐G‐A‐G‐G‐T), which is complementary to the 3′ end of 16‐S RNA, inhibits the formation of the complex between the 30‐S subunit and MS2 RNA described in the preceding paper. If the complex is preformed, the octanucleotide cannot prevent entry of the complex into the ribosome cycle upon supplementation with the ...

Nucleic Acids Research, 2012 16S ribosomal RNA gene (rDNA) amplicon analysis remains the standard approach for the cultivation-independent investigation of microbial diversity. The accuracy of these analyses depends strongly on the choice of primers.

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

Mutations in 16S ribosomal RNA disrupt antibiotic-RNA interactions. [PDF]
The EMBO Journal, 1989 Two of six mutations at a base-paired site in Escherichia coli 16S rRNA confer resistance to nine different aminoglycoside antibiotics in vivo. Chemical probing of mutant and wild-type ribosomes in the presence of paromomycin indicates that interactions between the antibiotic and 16S rRNA in mutant ribosomes are disrupted.
