Alternative conformations in Escherichia coli 16S ribosomal RNA. [PDF]

open access: yesProceedings 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 ...

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein

open access: yesFEBS Open Bio, EarlyView.
Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

MOLECULAR IDENTIFICATION OF SEVERAL CLINICALLYIMPORTANT BACTERIA INCLUDING ENTEROBACTERIA BYPARTIAL 16S RIBOSOMAL RNA GENE SEQUENCE COMPARISON

open access: yesZdravniški 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

N-TERMINAL PROCESSING OF RIBOSOMAL PROTEIN L27 IN STAPHYLOCOCCUS AUREUS [PDF]

open access: yes, 2012
The bacterial ribosome is essential to cell growth yet little is known about how its proteins attain their mature structures. Recent studies indicate that certain Staphlyococcus aureus bacteriophage protein sequences contain specific sites that may be ...

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

open access: yesFEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Tick-associated diseases identified from hunting dogs during the COVID-19 pandemic in a Mayan community in Yucatan, Mexico

open access: yesOpen Veterinary Journal, 2023
Background: Hunting activity in the Mayan communities has increased due to COVID-19 and domestic dogs have gained more importance. Due to its proximity to humans, domestic dogs are a bridge between tick-borne diseases and humans and their peri-domestic ...

454-Pyrosequencing: A Molecular Battiscope for Freshwater Viral Ecology [PDF]

open access: yes, 2010
Viruses, the most abundant biological entities on the planet, are capable of infecting organisms from all three branches of life, although the majority infect bacteria where the greatest degree of cellular diversity lies.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Aneurysm Infection Caused by Desulfovibrio desulfuricans

open access: yesEmerging 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.
