Reading canonical and modified nucleobases in 16S ribosomal RNA using nanopore native RNA sequencing. [PDF]

open access: yesPLoS ONE, 2019
The ribosome small subunit is expressed in all living cells. It performs numerous essential functions during translation, including formation of the initiation complex and proofreading of base-pairs between mRNA codons and tRNA anticodons.

A Mutant Era GTPase Suppresses Phenotypes Caused by Loss of Highly Conserved YbeY Protein in Escherichia coli

open access: yesFrontiers in Microbiology, 2022
Ribosome assembly is a complex fundamental cellular process that involves assembling multiple ribosomal proteins and several ribosomal RNA species in a highly coordinated yet flexible and resilient manner.

A comparison of structural and evolutionary attributes of Escherichia coli and Thermus thermophilus small ribosomal subunits: signatures of thermal adaptation. [PDF]

open access: yesPLoS ONE, 2013
Here we compare the structural and evolutionary attributes of Thermus thermophilus and Escherichia coli small ribosomal subunits (SSU). Our results indicate that with few exceptions, thermophilic 16S ribosomal RNA (16S rRNA) is densely packed compared to

A functional pseudoknot in 16S ribosomal RNA. [PDF]

open access: yesThe EMBO Journal, 1991
Several lines of evidence indicate that the universally conserved 530 loop of 16S ribosomal RNA plays a crucial role in translation, related to the binding of tRNA to the ribosomal A site. Based upon limited phylogenetic sequence variation, Woese and Gutell (1989) have proposed that residues 524-526 in the 530 hairpin loop are base paired with residues

The structure of a methylated tetraloop in 16S ribosomal RNA [PDF]

open access: yesStructure, 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 ...

Exclusion model of mRNA translation with collision-induced ribosome drop-off [PDF]

open access: yesJ. Phys. A: Math. Theor. 56 385601 (2023), 2023
The translation of messenger RNA transcripts to proteins is commonly modeled as a one-dimensional totally asymmetric exclusion process with extended particles. Here we focus on the effects of premature termination of translation through the irreversible detachment of ribosomes.

Evaluation and utility of mitochondrial ribosomal genes for molecular systematics of parasitic nematodes

open access: yesParasites & 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.

Mediating Ribosomal Competition by Splitting Pools [PDF]

open access: yesLCSS Vol 5 Issue 5 (Nov 2020), 2020
Synthetic biology constructs often rely upon the introduction of "circuit" genes into host cells, in order to express novel proteins and thus endow the host with a desired behavior. The expression of these new genes "consumes" existing resources in the cell, such as ATP, RNA polymerase, amino acids, and ribosomes. Ribosomal competition among strands of

Functional Modification of 16S Ribosomal RNA by Kethoxal [PDF]

open access: yesProceedings 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 ...
