Ribozyme - Wikipedia
网页Examples of ribozymes include the hammerhead ribozyme, the VS ribozyme, leadzyme, and the hairpin ribozyme. Researchers who are investigating the origins of life through the RNA world hypothesis have been working on discovering a ribozyme with the capacity to self-replicate, which would require it to have the ability to catalytically synthesize ...
Ribozymes: Catalytic RNAs that cut things, make things, and do …
网页Besides providing a powerful avenue to ribozyme-mediated gene inactivation (see below), trans-acting ribozymes are amenable to the complete arsenal of enzymology, including pre-steadystate and steady-state kinetic analysis.
What are Ribozymes? - News-Medical.net
网页2023年7月24日 · A ribozyme is a ribonucleic acid (RNA) enzyme that catalyzes a chemical reaction. The ribozyme catalyses specific reactions in a similar way to that of protein enzymes.
6.7: Ribozymes - RNA Enzymes - Biology LibreTexts
网页2023年7月13日 · The term ribozyme is used for RNA that can act as an enzyme. Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower eukaryotes. Ribozymes were first discovered in 1982 when Tom Cech’s laboratory observed Group I introns acting as enzymes.
Ribozyme - an overview | ScienceDirect Topics
网页A ribozyme is an RNA molecule that can cleave phosphodiester bonds independently of protein-based enzymes. It can be delivered in vivo as synthetic oligonucleotides or expressed from transgenes, with various chemical modifications tested to enhance stability, delivery, hybrid strength, and cleavage efficiency.
Ribozymes - Latest research and news | Nature
网页2024年7月27日 · A ribozyme is a ribonucleic acid (RNA) molecule with the ability to catalyze a biochemical reaction a function more commonly carried out by proteins.
Ribozymes, riboswitches and beyond: regulation of gene …
网页For instance, riboswitches alter their conformations in response to small metabolites. However, the identification of the bacterial ribozyme glmS, which specifically binds a metabolite and cleaves the mRNA encoding the protein that controls the metabolism of that metabolite, has established a closer link between riboswitches and ribozymes 7 ...
Ribozymes and RNA Catalysis: Introduction and Primer
网页2007年11月15日 · In principle, the great selectivity of ribozyme-induced cleavage of a chosen sequence could provide an opportunity to interfere with gene expression if targeted to a specific mRNA; this should ideally be the basis …
