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 ...

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 findings ...

Gene editing is one of the latest breakthroughs in biology. The widely known CRISPR-Cas gene editing system provided prokaryotes (organisms that lack cell nuclei) an immunity against foreign DNA.

The structure of a key enzyme involved in protein production is revealed by cryo-electron microscopy (cryo-EM). Using cryo-EM, researchers at Goethe University (Frankfurt, Germany) shed light on ...

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 ...

Although many organisms capture and respond to sunlight, enzymes - proteins that catalyze biochemical reactions - are rarely driven by light. A new study captures the full cycle of complex structural ...

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 ...

Deep in your muscles, an enzyme called AMPD1 helps turn chemical fuel into usable energy. When it does not work well, muscles tire faster.
