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

WEHI researchers have led a major global effort to create the first authoritative atlas for a class of enzymes that regulate almost every cellular process in the human body. Published in Cell, the ...

Doctors have long treated heart attacks, improved asthma symptoms and cured impotence by increasing levels of a single molecule in the body: nitric oxide. The tiny molecule can change how proteins ...

CHAMPAIGN, Ill. — A new artificial intelligence tool can predict the functions of enzymes based on their amino acid sequences, even when the enzymes are unstudied or poorly understood. The researchers ...

Researchers at Freiburg University discover new functions of the widely disseminated, yet little understood ENDOU enzyme. The family of ENDOU enzymes is found in most organisms, yet its functions are ...

A central question in molecular biology is how cells protect their chromosomes from damage during repeated cell division. At ...

NEW ORLEANS — Abnormal blood lipids – such as alterations in total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and high-density lipoprotein-cholesterol (HDL-C) – ...

Carbohydrate chains play physiologically relevant roles. For instance, many biologically important proteins and lipids inside our body have carbohydrate chains attached to them. These “sugar” chains, ...

With the aid of X-ray crystallography, researchers at the University of Michigan have revealed the structures of two closely related enzymes that play essential roles in the body's ability to ...
