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 ...

Sir2, an enzyme belonging to sirtuins, has been shown to be involved in the deacetylation of proteins. Researchers from the Institute of Science Tokyo reveal that a tandem allosteric effect of ...

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 ...

Every year, thousands of tons of brown algae are extracted from the seabed to obtain compounds such as alginates, a polymer composed of sugars that has high density and strength, offering potential ...

Ten years ago, researchers obtained the first crystal structure of Dicer, a key enzyme in a biological process called RNA interference (RNAi). In RNAi, a process also known as gene silencing, a short ...

Scientists have made an important discovery in meiosis research. They have identified a new mechanism that plays an important role in meiosis. The Research Group headed by molecular biologist Andrea ...

Molybdenum trioxide nanoparticles oxidize sulfite to sulfate in liver cells in analogy to the enzyme sulfite oxidase, researchers have found. The functionalized Molybdenum trioxide nanoparticles can ...

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 international research team has published a study in the journal The FEBS Journal that significantly advances the knowledge of a rare hereditary metabolic disease: classical homocystinuria. The ...

Researchers at Helmholtz Munich, the Technical University of Munich and the LMU University Hospital Munich uncovered a ...

BUFFALO, N.Y. — 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 ...
