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 ...

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 ...

This article shows how enzymatic activity can be effectively determined by means of the Eppendorf BioSpectrometer. The preliminary measurements were carried out by utilizing the “single λ-continuous” ...

Sir2, an enzyme belonging to sirtuins, has been shown to be involved in the deacetylation of proteins. Researchers from the ...

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 ...

New research identifies several existing compounds that block replication of the COVID-19 virus (SARS-CoV-2) within human cells grown in the laboratory. The inhibitors all demonstrated potent chemical ...

To be used industrially, enzymes usually need to undergo some surgery before they can become chemical workhorses. It may take a nip here, or a tuck there, to sculpt their active site into a shape that ...
