Analogs of the Catechol Derivative Dynasore Inhibit HIV-1 Ribonuclease H, SARS-CoV-2 nsp14 Exoribonuclease, and Virus Replication

Viruses, 2023
Viral replication often depends on RNA maturation and degradation processes catalyzed by viral ribonucleases, which are therefore candidate targets for antiviral drugs.

Preliminary studies on ribonucleases from Poa pratensis seeds

Acta Societatis Botanicorum Poloniae, 2015
Ribonuclease was extracted from Poa pratensis seeds with 0.1 M acetate buffer, pH 5.1, and then precipitated with alcohol. The enzyme was separated into 5 fractions (I-V) after chromatography on DEAE-cellulose at pH 5.1.

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.

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 ...
