Researchers devised a reversibly lockable DNA device for enclosing an enzyme and controlling its access to substrates. Turning on and off the activity of a single enzyme on demand is a much desired ...

NIH/Eunice Kennedy Shriver National Institute of Child Health and Human Development Researchers at the National Institutes of Health have discovered that a rare tumor of the adrenal glands appears to ...

Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic ...

Backed by the combined expertise of three USC schools, scientists are developing a new drug aimed at a previously unexplored ...

During photosynthesis, an enzyme called rubisco catalyzes a key reaction—the incorporation of carbon dioxide into organic compounds to create sugars. However, rubisco, which is believed to be the most ...

Chemists have long dreamed of mimicking nature’s precision, and now, thanks to a repurposed enzyme, they’ve taken a leap closer. Researchers at the University of Basel have successfully combined a ...

New research identifies several existing compounds that block replication of the COVID-19 virus (SARS-CoV-2) within human cells grown in the laboratory. The inhibitors all demonstrated potent chemical ...

Far from having adverse effects limited to the mouth, smokeless tobacco affects the normal function of a key family of enzymes found in almost every organ in the body, according to the first report on ...

Steviol glycosides, natural sweeteners extracted from Stevia rebaudiana, are widely used as sucrose substitutes due to their ...

Researchers from UT Austin have discovered insights about an enzyme that can protect cells from oxidative stress. Oxidative stress – a condition that is linked to sources like air pollutants and ...
