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 at the U.S. Department of Energy's Brookhaven National Laboratory have produced the first atomic-level structure of an enzyme that selectively cuts carbon-hydrogen bonds—the first and most ...

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 ...

Cancer cells have an insatiable appetite for energy as they multiply more rapidly than normal cells. Greedy cancer cells hijack various cellular functions to find and exploit energy and other ...

Researchers have made a major breakthrough earlier this year in the field of evolutionary conservation of molecular dynamics in enzymes. Their work points to potential applications in health, ...

Structural models of PLD3 and PLD4, enzymes that degrade nucleic acids in the cytoplasm. The enzymes' active (or binding) sites are indicated with black arrows. LA JOLLA, CA—When nucleic acids like ...

Enzymes are molecular machines that carry out the chemical reactions that sustain all life, an ability that has captured the attention of scientists like me. Consider muscle movement. Your body ...

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 ...

UPTON, NY—Scientists studying a COVID-19 coronavirus enzyme at temperatures ranging from frosty to human-body warm discovered subtle structural shifts that offer clues about how the enzyme works. The ...

Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules. A central part of this network is folate metabolism, a process that ...
