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 ...

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 ...

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 ...

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 ...

When nucleic acids like DNA or RNA build up in a cell's cytoplasm, it sets off an alarm call for the immune system. Enzymes usually clear these nucleic acids before they cause an issue, but when these ...

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 ...
