Research on structure, mechanism and regulation of enzyme activity. Works of Nobel laureates C. Anfinsen, S. Moore, W. Stein, S. Prusiner, J. Skou, P. Boyer, J. Walker [PDF]
The Ukrainian Biochemical Journal, 2020 Although the protein nature of enzymes was identified in the 40s of the 20th century, (we wrote about this in our previous article), their molecular structure and the specific mechanism of action remained unknown.

Ribonucleolytic resection is required for repair of strand displaced nonhomologous end-joining intermediates [PDF]
, 2013 Nonhomologous end-joining (NHEJ) pathways repair DNA double-strand breaks (DSBs) in eukaryotes and many prokaryotes, although it is not reported to operate in the third domain of life, archaea. Here, we describe a complete NHEJ complex, consisting of DNA

A conformational RNA zipper promotes intron ejection during non-conventional XBP1 mRNA splicing. [PDF]
, 2015 The kinase/endonuclease IRE1 is the most conserved signal transducer of the unfolded protein response (UPR), an intracellular signaling network that monitors and regulates the protein folding capacity of the endoplasmic reticulum (ER).

Ribonuclease and Ribonuclease-Inhibitors Among Higher Plants
Experimental Biology and Medicine, 1955 Summary1) Aqueous extracts prepared from 41 common plants were tested for ribonuclease activity and for capacity to inhibit pancreatic ribonuclease. Extracts of 5 plants (Phlox sp., Lathyrus sp., Asclepias syriaca, Allium sp. and Yucca filamentosa) were found capable of degrading ribonucleic acid, and these plants appear to constitute new sources of ...

Genetic diversity of human RNase 8
BMC Genomics, 2012 Background Ribonuclease 8 is a member of the RNase A family of secretory ribonucleases; orthologs of this gene have been found only in primate genomes. RNase 8 is a divergent paralog of RNase 7, which is lysine-enriched, highly conserved, has prominent ...

Drosophila CG3303 is an essential endoribonuclease linked to TDP-43-mediated neurodegeneration [PDF]
, 2017 Endoribonucleases participate in almost every step of eukaryotic RNA metabolism, acting either as degradative or biosynthetic enzymes. We previously identified the founding member of the Eukaryotic EndoU ribonuclease family, whose components display ...

Programmed genome editing of the omega-1 ribonuclease of the blood fluke, Schistosoma mansoni
eLife, 2019 CRISPR/Cas9-based genome editing has yet to be reported in species of the Platyhelminthes. We tested this approach by targeting omega-1 (ω1) of Schistosoma mansoni as proof of principle.
