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

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 ...

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 ...

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 ...

A team of researchers at the Hormel Institute has made a key finding in stem cell research. The team has proposed a mechanism for the control of whether embryonic stem cells continue to multiply and ...

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 ...

Enzymes are proteins that facilitate biochemical reactions by acting as a catalyst, and thus, their expression and activity have a strong influence on the reactions taking place within cells. As ...

Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...

Konstanz researchers identify an enzyme that plays a role in the migration of cells in our body—not only during normal tissue formation and wound healing, but also when tumor cells metastasize. This ...

Mitochondrial diseases are severe, often untreatable, and they leave human cells unable to grow normally without outside help. A new study published in Nature Metabolism now shows that a single gene ...
