Dual RNase and β-lactamase Activity of a Single Enzyme Encoded in Archaea
Life, 2020 β-lactam antibiotics have a well-known activity which disturbs the bacterial cell wall biosynthesis and may be cleaved by β-lactamases. However, these drugs are not active on archaea microorganisms, which are naturally resistant because of the lack of β ...

Influence of sex differences on microRNA gene regulation in disease. [PDF]
, 2014 Sexual dimorphism is observed in most human diseases. The difference in the physiology and genetics between sexes can contribute tremendously to the disease prevalence, severity, and outcome.

Dolphin Morbillivirus Associated with a Mass Stranding of Sperm Whales, Italy [PDF]
, 2017 In September 2014, 7 sperm whales stranded along the Adriatic Italian coastlines. Postmortem investigations on 3 dead females dead and in 1 fetus harbored by the largest one revealed molecular and immunoistochemical evidences of dolphin morbillivirus ...

Biological Activities of Secretory RNases: Focus on Their Oligomerization to Design Antitumor Drugs
Frontiers in Immunology, 2019 Ribonucleases (RNases) are a large number of enzymes gathered into different bacterial or eukaryotic superfamilies. Bovine pancreatic RNase A, bovine seminal BS-RNase, human pancreatic RNase 1, angiogenin (RNase 5), and amphibian onconase belong to the ...

“Life is short, and art is long”: RNA degradation in cyanobacteria and model bacteria
mLife, 2022 RNA turnover plays critical roles in the regulation of gene expression and allows cells to respond rapidly to environmental changes. In bacteria, the mechanisms of RNA turnover have been extensively studied in the models Escherichia coli and Bacillus ...

Identification of the catalytic motif of the microbial ribosome inactivating cytotoxin colicin E3 [PDF]
, 2004 Colicin E3 is a cytotoxic ribonuclease that specifically cleaves 16S rRNA at the ribosomal A-site to abolish protein synthesis in sensitive Escherichia coli cells.

Philosophical Transactions of the Royal Society B: Biological Sciences, 2011 The gene coding for the RNA subunit of ribonuclease P (RNase P) is essential in all free-living organisms. The RNA subunit, itself, is an enzyme and, from its evolutionary tree, we can infer that it is a very ancient molecule. The specificity of this enzyme is that it cleaves other RNA molecules at the junction of single-stranded and the 5′ end of ...

RNA-Binding Proteins Driving the Regulatory Activity of Small Non-coding RNAs in Bacteria
Frontiers in Molecular Biosciences, 2020 Small non-coding RNAs (sRNAs) are critical post-transcriptional regulators of gene expression. Distinct RNA-binding proteins (RBPs) influence the processing, stability and activity of bacterial small RNAs.
