Researchers devised a reversibly lockable DNA device for enclosing an enzyme and controlling its access to substrates. Turning on and off the activity of a single enzyme on demand is a much desired ...

A team of Michigan State University scientists -- using a new cooling method they created -- have uncovered the inner workings of a key iron-containing enzyme, a discovery that could help researchers ...

Revealing all the steps required to activate an enzyme called a protein kinase may identify new ways to target cancer, according to new University of Arizona-led research. Not only must the kinase ...

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-which is particularly ...
