An international research team led by the University of Leicester has made a breakthrough advance by trapping an intermediate in the mechanism of enzymes called heme peroxidases and determining its ...

Researchers have made use of cryo-electron microscopy to show the exact process of enzyme activation. Pandinus imperator, the emperor scorpion, is not only popular as a pet, but is also of interest ...

WITH our present knowledge of enzyme processes any conception of their mechanism must be essentially highly speculative. In the work under notice the author makes no claim to deal comprehensively with ...

Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial pathogen that is often associated with healthcare settings but can cause serious infections in anyone. These illnesses are difficult ...

DALLAS – July 19, 2002 – UT Southwestern Medical Center at Dallas researchers, using X-ray crystallography, have discovered how a particular cell enzyme finds its target and clearly carries out its ...

The enzyme Nocturnin, which governs daily tasks such as fat metabolism and energy usage, works in an entirely different way than previously thought, reported a team of researchers at Princeton ...

A new study led by scientists at IUPUI and Indiana University Bloomington is the first to describe a biochemical mechanism that increases the activity of a molecule whose presence is observed in many ...

An enzyme that plays a pivotal role in controlling genes in yeast acts through a more versatile mechanism than was previously thought to be the case, according to a new study by researchers at The ...

A team of researchers in China has found a reaction mechanism unprecedented for the many enzymes that add methyl groups to biomolecules. Although NosN uses two SAM molecules, neither of them serves ...

In plants, oxylipins regulate developmental processes and defense responses. The first specific step in the biosynthesis of the cyclopentanone class of oxylipins is catalyzed by allene oxide cyclase ...

In the human body, proteins called enzymes help speed up chemical reactions that are vital for life. After you eat, enzymes help your body break down food and obtain energy. Enzymes are also ...
