Programmed genome editing of the omega-1 ribonuclease of the blood fluke, Schistosoma mansoni
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.

Structural insight into precursor ribosomal RNA processing by ribonuclease MRP
Adapted to the task at hand RNA-based catalysts perform fundamental tasks in cellular RNA metabolism, especially in eukaryotes, where RNAs are cut by specialized ribonucleoproteins (RNPs) as part of ribosome assembly or messenger RNA regulation or ...

Horse Pancreatic Ribonuclease [PDF]
Horse ribonuclease was purified after acid extraction of pancreas by ammonium sulfate fractionation and chromatography on CM‐cellulose. It is a glycoprotein with an average molecular weight of about 18000. The pure enzyme was chromatographically and electrophoretically heterogeneous due to the heterogeneity of the carbohydrate moiety.The amino‐acid ...

A Type III CRISPR Ancillary Ribonuclease Degrades Its Cyclic Oligoadenylate Activator
Cyclic oligoadenylate (cOA) secondary messengers are generated by type III CRISPR systems in response to viral infection. cOA allosterically activates the CRISPR ancillary ribonucleases Csx1/Csm6, which degrade RNA non-specifically using a HEPN (Higher ...

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 ...

CRYSTALLINE RIBONUCLEASE [PDF]
1. A crystalline enzyme capable of digesting yeast nucleic acid has been isolated from fresh beef pancreas. 2. The enzyme called "ribonuclease" is a soluble protein of albumin type. Its molecular weight is about 15,000. Its isoelectric point is in the region of pH 8.0. 3.

The Immunomodulatory and Antimicrobial Properties of the Vertebrate Ribonuclease A Superfamily
The Ribonuclease A Superfamily is composed of cationic peptides that are secreted by immune cells and epithelial tissues. Although their physiological roles are unclear, several members of the vertebrate Ribonuclease A Superfamily demonstrate ...
