Creating and examining 10,296 mutants of a ribozyme leads to a better understanding of these widespread but understudied RNA molecules. Ribozymes – ribonucleic acid enzymes – are RNA molecules that ...
The glmS ribozyme resides in the 5′ untranslated region of glmS mRNA and functions as a catalytic riboswitch that regulates amino sugar metabolism in certain Gram-positive bacteria. The ribozyme ...
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like ...
In the present study, as an alternative strategy for survivin inhibition, we designed two hammerhead ribozymes against human survivin mRNA and examined the function of the ribozymes and the effects of ...
Researchers have now uncovered the 3D structure of the RNA enzyme SAMURI. Their study provides insights into the development of ribozymes and the evolution of catalytically active RNA. Researchers led ...
In new research published in the journal Angewandte Chemie, scientists applied a high throughput methodology to study the ribozyme in an innovative way. While work in this area has typically used ...
RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study ...
RNA molecules are an integral part of the human body: In cells, they ensure the transfer of genetic information and regulate the activity of genes. Some even act as catalysts, allowing chemical ...
Atomic-resolution structure of a ribozyme yields insights into RNA catalysis and the origins of life
Santa Cruz, CA — Which came first, nucleic acids or proteins? This question is molecular biology’s version of the “chicken-or-the-egg” riddle. Genes made of nucleic acids (DNA or RNA) contain the ...
RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study ...
One serious limitation with current gene therapy strategies is a lack of control. When researchers deliver a gene to replace one linked to disease, there’s no way to turn on the therapeutic gene at ...
A new method can test the activity of thousands of RNA enzymes, called ribozymes, in a single experiment. The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA ...
