The equilibrium distributions of hairpin ribozyme conformational isomers have been examined by time-resolved fluorescence resonance energy transfer. Ribozymes partition between active (docked) and ...
RNA molecules are real all-rounders. They transfer the genetic information from the DNA in the cell. They regulate the activity of genes. And some of them have a catalytic effect: just like enzymes, ...
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 ...
The first stage of the process to develop a DU-containing catalyst involved substituting as many of the G residues as possible by either D or U, while still retaining some detectable activity.
Ribozymes are RNA molecules that are capable of catalyzing a chemical reaction. Ribozymes occur naturally inside cells where they play an essential role in the ribosome, joining amino acids together ...
A team led by Prof. Zhang Kaiming from the University of Science and Technology (USTC) solved six conformations in the second-step self-splicing of Tetrahymena ribozyme using cryogenic electron ...
Atomic-resolution structure of a ribozyme yields insights into RNA catalysis and the origins of life
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 instructions for ...
Researchers have developed the first cross-chiral biocatalyst—a right-handed (D) RNA enzyme that catalyzes the linkage of left-handed (L) RNA nucleotides into L-RNA chains. No other RNA or protein ...
A study finds that an RNA enzyme, or ribozyme, can evolve to produce complex RNAs efficiently but at the cost of synthesis accuracy. Key to the development of RNA-based life, which is thought to have ...
In most modern cells, DNA stores the genetic blueprint, and relies on proteins to replicate, repair and build from those blueprints. At the same time, proteins require instructions from DNA to be made ...
Important progress for RNA research: A team has discovered a new ribozyme that can label RNA molecules in living cells. RNA molecules are real all-rounders. They transfer the genetic information from ...
