Many leukemias are caused by loss of the enzyme Pten. Some anti-leukemia treatments work by inhibiting another enzyme called Shp2. Researchers have now found that mice lacking both of these enzymes ...

Enzymes are biomolecules that perform specialized functions, such as the assembly or degradation of small molecules. The small size of enzymes (tens of nanometres) previously limited their study to ...

The study may help explain a phenomenon noticed by researchers and primary care physicians alike: adults in their 40s may eat less and exercise more, but not see the results in weight loss. The ...

A research team at Leibniz-HKI has described a new enzyme that renders the highly toxic molecule malleicyprol harmless.

New science out of Stanford University could one day lead to revolutionary new drugs for the treatment of alcohol addiction. A study, to be published Friday in Science, puts forward a new theory on ...

DURHAM, N.C. -- Researchers at Duke University Medical Center have provided the first direct evidence in mice for the role of an enzyme that specifically controls the production of serotonin in the ...

Mimicking natural evolution in a test tube, scientists have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth. Mimicking natural evolution in a test ...

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...

A subtle flaw in a single brain enzyme now looks like one of the earliest sparks that can set dementia in motion. Instead of a slow, mysterious slide into memory loss, researchers are tracing a direct ...

Liver enzymes can fluctuate due to factors like hormonal changes or reactions to medications. Fluctuations are often temporary, but long-term changes may indicate a condition that requires medical ...

An enzyme may help explain why anecdotal reports suggest men are more likely than women to suffer from the coronavirus and its severe complications, a new study shows. The study, published in the peer ...

LA JOLLA, CA—October 29, 2014—Mimicking natural evolution in a test tube, scientists at The Scripps Research Institute (TSRI) have devised an enzyme with a unique property that might have been crucial ...
