How do related proteins develop different functions? This is the question investigated by a research team involving Kiel ...

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 ...

Researchers have made a significant advance toward the goal of using bacteria—rather than fossil fuels—to produce ethylene, a key chemical in the production of many plastics. In a new study, ...

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 ...

Reporting in Science, researchers at UC Santa Barbara, UCSF and the University of Pittsburgh have developed a new workflow for designing enzymes from scratch, paving the way toward more efficient, ...

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 ...

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 ...

Enzymes emerged before the last universal common ancestor, making comparative genetic analyses insufficient to understand the earliest stages of enzyme evolution. Researchers at Science Tokyo have ...

A chance discovery at Nagoya University in Japan has shown that a well-known brain enzyme has a hidden ability: It builds a sugar chain on itself, becomes secreted from the cell and deactivates, then ...
