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 ...

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 ...

A research team led by a biochemist at the University of California, Riverside has solved the crystal structure for an enzyme that plays a key role in DNA methylation, the process by which methyl ...

Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic material (chromosomes) equally, and then rebuild the nuclear envelope around ...

Scientists discovered a key molecular switch to keep neurons healthy by controlling the disassembly and assembly of their energy-generating powerhouses, the mitochondria. The study illustrates how a ...

Chemists at MIT have introduced an engineered biosynthetic enzyme that accepts a wider range of substrates into periwinkle plant culture to make unnatural analogs of alkaloids (Nat. Chem. Biol., DOI: ...

NIH/Eunice Kennedy Shriver National Institute of Child Health and Human Development Researchers at the National Institutes of Health have discovered that a rare tumor of the adrenal glands appears to ...
