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.

Choice of 16S Ribosomal RNA Primers Impacts Male Urinary Microbiota Profiling

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Accessibility to next-generation sequencing (NGS) technologies has enabled the profiling of microbial communities living in distinct habitats. 16S ribosomal RNA (rRNA) gene sequencing is widely used for microbiota profiling with NGS technologies.

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 ...

Role of 16‐S RNA in Ribosome Messenger Recognition [PDF]

open access: yesEuropean 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 ...

Recognition of Ribosomal RNA Sites in DNA, I. Analysis of the E. coli System [PDF]

open access: yes, 1965
The evidence recently presented of specific hybridization between bacterial ribosomal RNA and homologous DNA1-3 has indicated the possibility of a biochemical approach to the problem of the identification of ribosomal RNA sites in DNA.

Ribosomal Protein S12 Hastens Nucleation of Co-Transcriptional Ribosome Assembly

open access: yesBiomolecules, 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
