Scientists have captured atomic level snapshots showing how one key enzyme modifies a protein involved in turning genes on or off inside cells. Understanding this process helps explain how complex ...

Current demand for plastics and chemical raw materials is met through large-scale production of ethylene from fossil fuels.

Researchers have determined the structure of a key part of the enzyme telomerase, which is active in most cancers and enables cancer cells to proliferate indefinitely. The new findings reveal how the ...

The structure of enzymes determines how they control vital processes such as digestion or immune response. This is because the protein compounds are not rigid, but can change their shape through ...

Transfer RNAs (tRNAs) are among the most common types of RNA in a cell and are indispensable for protein production in all known organisms. They have an important "translation" function: They ...

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 ...

Over-activation of telomerase in 90 percent of malignant tumors has made the unusual enzyme a prime target for drug development efforts Researchers at UC Santa Cruz have determined the structure of a ...
