Fifty Shades of Erns: Innate Immune Evasion by the Viral Endonucleases of All Pestivirus Species
Viruses, 2022 The genus Pestivirus, family Flaviviridae, includes four historically accepted species, i.e., bovine viral diarrhea virus (BVDV)-1 and -2, classical swine fever virus (CSFV), and border disease virus (BDV).

Colicin E3: A Unique Endoribonuclease [PDF]
Proceedings of the National Academy of Sciences, 1973 The question of whether or not a cellular ribonuclease is involved in the cleavage of 16S ribosomal RNA by colicin E3 was investigated. For this purpose ribosomes from strains devoid of some ribonucleases or ribosomes in which ribonucleases had been inactivated by heat or removed by extensive washings were used for the colicin reaction.

Nature Communications, 2020 Bacterial RNA degradation is typically initiated by endoribonucleases and followed by exoribonucleases. Here the authors report the targetome of endoRNase Y in Streptococcus pyogenes, revealing the interplay between RNase Y and 3′-to-5′ exoribonuclease ...

Frontiers in Immunology, 2022 Alu retrotransposons belong to the class of short interspersed nuclear elements (SINEs). Alu RNA is abundant in cells and its repetitive structure forms double-stranded RNAs (dsRNA) that activate dsRNA sensors and trigger innate immune responses with ...

RNA promotes phase separation of glycolysis enzymes into yeast G bodies in hypoxia
eLife, 2020 In hypoxic stress conditions, glycolysis enzymes assemble into singular cytoplasmic granules called glycolytic (G) bodies. G body formation in yeast correlates with increased glucose consumption and cell survival.

Agronomy, 2023 T2 ribonucleases are endoribonucleases that are found in every organism and that carry out important biological functions. In plants, T2 ribonucleases are organized into multi-gene families, and each member is thought to have a specific function. In this

Substrate specificity of human MCPIP1 endoribonuclease [PDF]
Scientific Reports, 2018 AbstractMCPIP1, also known as Regnase-1, is a ribonuclease crucial for regulation of stability of transcripts related to inflammatory processes. Here, we report that MCPIP1 acts as an endonuclease by degrading several stem-loop RNA structures and single-stranded RNAs.

Mutational and Kinetic Analysis of APE1 Endoribonuclease Activity [PDF]
Molecular Biology, 2021 Human apurinic/apyrimidinic endonuclease 1 (APE1) participates in the DNA repair system. It is believed that the main biological function of APE1 is Mg^(2+)-dependent hydrolysis of AP-sites in DNA. On the base of structural data, kinetic studies, and mutation analysis, the key stages of APE1 interaction with damaged DNA were established.

Sinorhizobium meliloti RNase III: Catalytic Features and Impact on Symbiosis
Frontiers in Genetics, 2018 Members of the ribonuclease (RNase) III family of enzymes are metal-dependent double-strand specific endoribonucleases. They are ubiquitously found and eukaryotic RNase III-like enzymes include Dicer and Drosha, involved in RNA processing and RNA ...

Sequence-specific endoribonucleases
Postępy Biochemii, 2016 Ribonucleases are nucleolytic enzymes that commonly occur in living organisms and act by cleaving RNA molecules. These enzymes are involved in basic cellular processes, including the RNA maturation that accompanies the formation of functional RNAs, as well as RNA degradation that enables removal of defective or dangerous molecules or ones that have ...
