Enzymes are large biological molecules—usually proteins—that speed up chemical reactions. Molecules that speed up chemical reactions but are unchanged afterwards are known as catalysts. The substances ...

The researchers engineered a benzaldehyde lyase enzyme from Pseudomonas fluorescens ... the active site to try substituting, as well as to probe the likely reaction mechanism.

More specifically, their research aims to help plants adapt to changing temperatures by introducing engineered enzymes that will increase plants' heat tolerance. Their recent paper is published in ...

But the protein kinases that suppress sleep and the dephosphorylation enzymes that control sleep and wakefulness have not been fully elucidated. Animals, including humans, require a certain amount ...

How does your body speed up these important reactions? The answer is enzymes. Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a ...

NASA's Parker Solar Probe is preparing for its long-anticipated record-setting approach to the surface of the sun. Hurtling around the sun at approximately 430,000 mph, the uncrewed vehicle is ...

Endocannabinoids, molecules naturally produced in the brain, play a critical role in regulating appetite, energy use, and ...

The accumulation of lipids in hepatocytes in nonalcoholic fatty liver disease (NAFLD) leads to an increase in reactive oxygen species and changes in the intracellular microenvironment, while ...

Through last year, scientists were at work reshaping human life and equipping it, and the world, for the challenges of the ...
