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 ...

Kanazawa University, have captured real-time images showing how a key brain enzyme organizes itself to help memory formation. Their study, published in Nature Communications, reveals that the enzyme ...

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 latest short science news items from C&EN. The team proposes that SAM plays a dual role in the reaction. It donates a methyl group to the enzyme’s cobalamin cofactor and then serves as a base when ...

A new method has enabled the natural structure of particularly large and complex enzymes to be revealed. Scientists have investigated a multi-enzyme complex that plays an essential role in metabolism ...

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 ...

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 ...

For the first time, the structure of a DNA enzyme complex implicated in infertility and cancer has been obtained using cryo-electron microscopy (cryo-EM). A collaboration of researchers, led by ...

Estrogen is known as an important hormone, and it can control many functions by regulating the activity of hundreds of genes.
