CRYSTALLINE RIBONUCLEASE [PDF]

open access: yesJournal of General Physiology, 1940
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.

Streptomyces RNases – Function and impact on antibiotic synthesis

open access: yesFrontiers in Microbiology, 2023
Streptomyces are soil dwelling bacteria that are notable for their ability to sporulate and to produce antibiotics and other secondary metabolites. Antibiotic biosynthesis is controlled by a variety of complex regulatory networks, involving activators ...

“Life is short, and art is long”: RNA degradation in cyanobacteria and model bacteria

open access: yesmLife, 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 ...

Surveillance of Tumour Development: The Relationship Between Tumour-Associated RNAs and Ribonucleases

open access: yesFrontiers in Pharmacology, 2019
Tumour progression is accompanied by rapid cell proliferation, loss of differentiation, the reprogramming of energy metabolism, loss of adhesion, escape of immune surveillance, induction of angiogenesis, and metastasis.

Ribonuclease and Ribonuclease-Inhibitors Among Higher Plants

open access: yesExperimental 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 ...

Magnetite Nanoparticles Functionalized with RNases against Intracellular Infection of Pseudomonas aeruginosa

open access: yesPharmaceutics, 2020
Current treatments against bacterial infections have severe limitations, mainly due to the emergence of resistance to conventional antibiotics. In the specific case of Pseudomonas aeruginosa strains, they have shown a number of resistance mechanisms to ...

Ribonuclease S redux [PDF]

open access: yesChem. Commun., 2011
The S-peptide and S-protein components of bovine pancreatic ribonuclease form a noncovalent complex with restored ribonucleolytic activity. Although this archetypal protein-fragment complementation system has been the object of historic work in protein chemistry, intrinsic limitations compromise its utility.

Biological Activities of Secretory RNases: Focus on Their Oligomerization to Design Antitumor Drugs

open access: yesFrontiers 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 ...
