Enzymes help with specific functions that are vital to the operation and overall health of the human body. They help speed up chemical reactions and are essential for respiration, digestion, muscle ...

Life has evolved over billions of years, adapting to the changing environment. Similarly, enzymes—proteins that speed up biochemical reactions (catalysis) in cells—have adapted to the habitats of ...

In a new study, researchers have discovered how an enzyme that plays a key role in cancer development functions. The researchers hope the new knowledge will lead to the design of more precise drugs.

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...

A dawning field of research, artificial biology, is working toward creating a genuinely new organism. At Princeton, chemistry professor Michael Hecht and the researchers in his lab are designing and ...
