It has been known in biology for a long time that the excited oxygen molecule singlet oxygen is the main cause of aging in cells. To counter this, nature uses an enzyme called superoxide dismutase to ...

Synthetic biology is a growing field of research that is aiming to create a new kind of organism. Engineering synthetic proteins that can perform simple cellular functions as they would in real life ...

Annotations of enzyme function provide critical starting points for generating and testing biological hypotheses, but the quality of functional annotations is hindered by uncertain assignments for ...

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.

Protein motions and structural dynamics play an important role in the evolution of new enzyme functions, an international team reports. Undertaking the process in both directions helps elucidate the ...

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 ...
