image: Synthesizing hybrid enzyme catalysts in situ to improve and expand enzymatic catalysis is an important way to address challenges of industrial biocatalysis. In this account, the construction ...
While most enzymatic activity is conducted through chemical binding interactions between molecules, in some cases, the mere presence of an enzyme can affect intracellular functions. While exploring ...
An international team of researchers has transferred certain structural characteristics of natural enzymes, which ensure particularly high catalytic activity, to metallic nanoparticles. The desired ...
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 ...
Scientists observed the characteristics of a single enzyme inside a nanopore. This revealed that the enzyme can exist in four different folded states, or conformers, that play an active role in the ...
Enzymology is the study of enzymes and enzyme-catalyzed reactions. Enzymes are biological catalysts that accelerate the rate of biological reactions. They can also perform multiple reactions ...
When nucleic acids like DNA or RNA build up in a cell's cytoplasm, it sets off an alarm call for the immune system. Enzymes usually clear these nucleic acids before they cause an issue, but when these ...
Using a series of more than 1,000 X-ray snapshots of the shapeshifting of enzymes in action, researchers at Stanford University have illuminated one of the great mysteries of life – how enzymes are ...
They say you can’t teach an old dog new tricks. But bathing an enzyme in blue-green light has enabled researchers to completely change its catalytic function, so that it carries out a ring-forming ...
