Researchers have used cryo- electron microscopy to elucidate for the first time the structure and function of a very small enzyme embedded in cell membranes. This enzyme builds complex sugar trees ...

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 ...

As sessile organisms, plants have to continually adapt their growth and architecture to the ever-changing environment. To do so, plants have evolved distinct molecular mechanisms to sense and respond ...

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 ...

While most enzymatic activity is conducted through chemical binding interactions between molecules, in some cases, the mere presence of an enzyme can affect intracellular functions. While exploring ...

The first structure of a lipin enzyme, which carries out an important step in the production of triglycerides, the main reservoir for long-term energy storage, will help scientists to better ...

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, ...

Acetolactate synthase, also known as acetohydroxyacid synthase (AHAS), is an enzyme involved in the branched chain amino acid biosynthesis pathway. AHAS is a thiamine diphosphate (ThDP)-dependent ...

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 ...

Current demand for plastics and chemical raw materials is met through large-scale production of ethylene from fossil fuels. This makes it necessary to search for new, renewable processes. Using ...
