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 ...

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 ...

SANTA CRUZ, CA -- Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or "ribozyme," that carries out a fundamental reaction ...

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 structure of enzymes determines how they control vital processes such as digestion or immune response. This is because the protein compounds are not rigid, but can change their shape through ...

Ten years ago, researchers obtained the first crystal structure of Dicer, a key enzyme in a biological process called RNA interference (RNAi). In RNAi, a process also known as gene silencing, a short ...

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 ...

Scientists discovered hundreds of energy-making enzymes secretly working on human DNA—revealing a hidden “mini-metabolism” ...

"This structure answers a long-standing question for how two essential regions, N-lip and C-lip, which are located on opposite ends of this protein in humans, come together to form a function enzyme ...

David Cantu and Tin Nguyen have received a 3-year, $599,999 grant from the National Science Foundation’s Cyberinfrastructure for Sustained Scientific Innovation (CSSI) Program to support the creation ...
