Healthy cells are constantly breaking down proteins and building up new ones with the help of enzymes aptly named unfoldases, because they unravel proteins tagged for destruction or recycling. Now, a ...

Researchers have observed enzymes breaking down cellulose to aid the production of biofuels. Biofuels obtained from biomass are becoming increasingly important. Apart from biomethane, however, they ...

Cel7A cellulase enzymes (gold) are inhibited when breaking down cellulose (green) by the product, cellobiose, at both the “front door" (1) and “back door" (2) of the Cel7A tunnel, and by two other ...

Using a new super-resolution microscope they've been able to see single molecules of the enzyme at work in a liver cancer cell line. Then they've used confocal microscopes to see how disrupting the ...

UNIVERSITY PARK, Pa. -- The construction of a new multimodal optical microscope, SCATTIRSTORM, that could enable more efficient bioenergy production, is the focus of a three-year, $1.5 million, U.S.

The enzyme RNA polymerase (RNAP) carries out transcription, copying DNA into RNA. It's the first step in gene expression, and ...

Focusing on an enzyme in yeast, they demonstrated how contrasts in atomic scale motions impact their function. The method promises unprecedented access to the mechanisms by which biomolecules work, ...

Enzymes help with specific functions that are vital to the operation and overall health of the human body. They help speed up chemical reactions and are essential for respiration, digestion, muscle ...

The reaction of macromolecules such as enzymes and antibodies with cell surfaces is often an inefficient process, requiring large amounts of expensive reagent. Here we report a general method based on ...

An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body, and can actually speed up the rate of a chemical reaction to help support life. Enzymes are produced ...
