Scientists show enhanced enzyme diffusion after catalysis actively drives reactions away from equilibrium, offering a new ...

A 91-year-old man with a history of bladder carcinoma and left total knee arthroplasty was evaluated because of left knee pain. A culture of synovial fluid showed no growth. A diagnosis was made.

From the 1950s to 1970s, discovery of enzymes began by identifying new chemical reactions within cell-free extracts, but ...

Frances Arnold's game-changing technique of "directed evolution" creates enzymes with unusual capabilities. Her own evolution made it possible.

Finding out how microbes make compounds containing the diazo chemical group could help researchers to synthesize useful ...

A resurrected ancient enzyme is helping scientists test how reliably Earth’s oldest rocks record signs of life.

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

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 ...

Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic ...

A catalyst is a substance that speeds up a chemical reaction. The catalyst is not used up or chemically changed during the reaction. Enzymes are catalysts that work inside the cells of living ...

Molecularly targeted therapies are increasingly relevant in clinical oncology, as they enable the selective modulation of specific biologic targets—such as enzymes or receptors—by inhibiting or ...
