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 ...

Determination of ribonuclease sequence-specificity using Pentaprobes and mass spectrometry.

RNA: A publication of the RNA Society, 2012
The VapBC toxin-antitoxin (TA) family is the largest of nine identified TA families. The toxin, VapC, is a metal-dependent ribonuclease that is inhibited by its cognate antitoxin, VapB. Although the VapBCs are the largest TA family, little is known about

Retrotransposon Expression Is Upregulated in Adulthood and Suppressed during Regeneration of the Limb in the Axolotl (Ambystoma mexicanum)

Advanced Biology, EarlyView.
The axolotl's remarkable regenerative abilities decline with age, the causes may include the numerous repetitive elements within its genome. This study uncovers how Ty3 retrotransposons and coexpression networks involving muscle and immune pathways respond to aging and regeneration, suggesting that transposons respond to physiological shifts and may ...

Functional plasticity of antibacterial EndoU toxins. [PDF]

, 2018
Bacteria use several different secretion systems to deliver toxic EndoU ribonucleases into neighboring cells. Here, we present the first structure of a prokaryotic EndoU toxin in complex with its cognate immunity protein.

Consolidate Overview of Ribonucleic Acid Molecular Dynamics: From Molecular Movements to Material Innovations

Advanced Engineering Materials, EarlyView.
Molecular dynamics simulations are advancing the study of ribonucleic acid (RNA) and RNA‐conjugated molecules. These developments include improvements in force fields, long‐timescale dynamics, and coarse‐grained models, addressing limitations and refining methods.

Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

Advanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Influence of gibberellic acid on hydrolytic enzymes activity in germinating different-aged lupin seeds

Acta Societatis Botanicorum Poloniae, 2015
The influence of GA3 -on the germination of different-aged lupin seed and α-amylase, protease and ribonuclease activity in the embryonic axis and cotyledons of these seeds were investigated after 24, 48, 72 and 96 h of germination. GA3 treatment of older

Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.
