Life has evolved over billions of years, adapting to the changing environment. Similarly, enzymes—proteins that speed up ...

These enzymes opened the path to a powerful research tool that scientists later used not only to sequence genomes, but also to create the first synthetic cell, two scientific research milestones ...

Scientists have long struggled to target proteins that lack defined structure and are involved in cancer, neurodegenerative ...

or enzyme activation, respectively. Because membrane receptors interact with both extracellular signals and molecules within the cell, they permit signaling molecules to affect cell function ...

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are essential for life, as they play a crucial role in various biological processes, such as digestion, ...

Life takes shape with the motion of a single cell. In response to signals from certain proteins and enzymes, a cell can start ...

Enzymes are also involved in the building up of chemical molecules elsewhere in the body. In an organism, the active site of each enzyme is a different shape. It is a perfect match to the shape of ...

If acetylcholine sticks around for too long, it can paralyze your muscles – including your heart muscle cells – and, well, that’s that. This is where the enzyme acetylcholinesterase comes in. This ...

Digestive enzymes are found in the digestive system, including the mouth, stomach, and small intestine. They help you break down food and absorb nutrients. Sometimes, the body cannot make enough ...

“In the absence of the causal link, contributions of individual APOBEC3 enzymes to mutations in cancer remained widely debated.” What the field was lacking before, Petljak explains, were human cancer ...

New research offers unprecedented insight into how an enigmatic enzyme, known as CDK7, drives the cell cycle and cell proliferation.

MIT scientists have discovered a way to control the movements of starfish cells using light, which could have biomedical applications.
