Nanopore reveals shape-shifting enzyme linked to catalysis

University of Groningen scientists have observed the characteristics of a single enzyme inside a nanopore. They learned that the enzyme can exist in four different folded states, or conformers, that play an active role in ...

A friendlier way to deal with nitrate pollution

Learning from nature, scientists from the Center for Sustainable Resource Science in Japan and the Korean Basic Science Institute (KBSI) have found a catalyst that efficiently transforms nitrate into nitrite—an environmentally ...

Researchers discover molecule's unusual cell-killing mechanism

Soon after Jake Eaton joined the lab of Stuart Schreiber at the Broad Institute of MIT and Harvard in 2015, the postdoctoral researcher became intrigued by some wild theories being debated by his colleagues. The theories ...

Biochemists trap and visualize an enzyme as it becomes active

How do you capture a cellular process that transpires in the blink of an eye? Biochemists at MIT have devised a way to trap and visualize a vital enzyme at the moment it becomes active—informing drug development and revealing ...

New molecular probes for opioid receptors

Strong painkillers are very important in the management of patients with cancer and heart attack or requiring surgery. They extert their effect by binding to so-called opioid receptors in the body.

Printing complex cellulose-based objects

Researchers from ETH Zurich and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have set a new world record: they 3-D printed complex objects with higher cellulose content than that of any other ...

Changes in surface sugarlike molecules help cancer metastasize

Changes in a specific type of sugarlike molecule, or glycan, on the surface of cancer cells help them to spread into other tissues, according to researchers at the University of California, Davis. Published March 23 in Proceedings ...

Controlling vitamin K2 production in the tuberculosis bacteria

A team of New Zealand researchers led by a University of Canterbury (UC) scientist has discovered a novel mechanism of controlling vitamin K2 production in the bacterial pathogen that causes tuberculosis (known as TB or the ...

New device quickly detects harmful bacteria in blood

Engineers have created a tiny device that can rapidly detect harmful bacteria in blood, allowing health care professionals to pinpoint the cause of potentially deadly infections and fight them with drugs.
