HANOVER, NH – By revealing the architecture of an essential enzyme in a parasite, Dartmouth researchers are helping address a public health issue. Researchers in the laboratory of Amy Anderson, ...

Within each cell, the power houses called mitochondria continuously break down molecules derived from food to generate energy as well as to produce new molecules that serve as building blocks of cells ...

Enzymes with specific functions are becoming increasingly important in industry, medicine and environmental protection. For ...

Researchers have determined the atom-by-atom structure of the fermentation enzyme phosphoketolase by cryogenic electron microscopy. They identified details that were mistakenly characterized by X-ray ...

The enzyme transhydrogenase plays a central role in regulating metabolic processes in animals and humans alike. Malfunction can lead to serious disorders. For the first time, structural biologists ...
