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 ...

A wobbly new biochemical structure in one scientist's lab may resemble what enzymes looked like billions of years ago, when life on Earth began to evolve -- long before they became ingredients for new ...
