Scientists discovered hundreds of energy-making enzymes secretly working on human DNA—revealing a hidden “mini-metabolism” ...

More than 200 metabolic enzymes, many of which are normally tasked with producing energy in the mitochondria, are also found sitting directly on top of human DNA, according to a study published in ...

Researchers from Sweden and the U.K. have devised a new method to curb cancer growth by shutting down a single enzyme and stopping cells from dividing. While switching off certain enzymes is an ...

Many of the most pressing health problems of our time start with obesity, so treating that root cause may be our best bet in many cases. Now, researchers at Yale have identified an enzyme in mice that ...

The key to changing blood types may be in the gut. Enzymes made by bacteria in the human digestive tract can strip the sugars that determine blood type from the surface of red blood cells in the lab, ...

Doctors have long treated heart attacks, improved asthma symptoms, and cured impotence by increasing levels of a single molecule in the body: nitric oxide. The tiny molecule can change how proteins ...

Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and ...

Enzymes help digest food, clean laundry, make perfumes, and build medicines. They also break down toxins in the environment. Because of their wide use, scientists have worked for years to create ...

Researchers have found that rhomboid enzymes, which are special proteins that cut other proteins, are able to break the 'cellular speed limit' as they move through the cell membrane. Johns Hopkins ...

Deep in our cells, a wide range of processes are occurring constantly. These cellular processes rely on enzymes to act as catalysts and set off a series of molecular interactions. There are still many ...

Printable sweat-powered biofuel cells could replace bulky batteries in thin, flexible wearable health sensors.

An enzyme called MARK2 has been identified as a key stress-response switch in cells in a study by researchers at Johns Hopkins Bloomberg School of Public Health. Overactivation of this type of stress ...
