UPTON, NY—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 ...

Hot vents in the deep sea are home to microbes that feed on ethane. Now researchers have succeeded in finding an important component in the microbial conversion of the gas. They were able to decode ...

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 ...

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 ...

A structural model of the telomerase enzyme shows how the binding domain (purple) tethers one end of the RNA component of the enzyme. (Image credit: Jansson et al., ) Researchers at UC Santa Cruz have ...

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 ...

Nitrilases are a unique class of enzymes that catalyse the hydrolysis of nitrile compounds to yield the corresponding carboxylic acids or amides. Their application in biotransformation processes has ...

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 ...

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 ...
