(SALT LAKE CITY)—Dicer, an enzyme essential for life, cleaves long double-stranded RNA (dsRNA) into short pieces that regulate gene expression. But in many ways dsRNA molecules all look alike, and ...
Primarily for its role in the silencing of genes via small RNAs, Dicer is an enzyme that fascinates biologists. Dicer proteins are large, complicated proteins that recognize double-stranded RNA (dsRNA ...
Nature: MicroRNA uses a gym to get fit for cuts by Dicer enzyme
MicroRNA uses a gym to get fit for cuts by Dicer enzyme
A new study in Nature has mapped, at atomic resolution, how the enzyme DICER slices precursor microRNAs at exactly the right spot, with accuracy down to a single nucleotide. The research, which ...

RNA-chopping enzyme Dicer stabilizes mammalian chromosomes with the help of BRD4 activator
Ten years ago, researchers obtained the first crystal structure of Dicer, a key enzyme in a biological process called RNA interference (RNAi). In RNAi, a process also known as gene silencing, a short ...
Enzyme, a catalyst that regulates the rate at which chemical reactions proceed in living organisms without itself being altered in the process. Most critically, enzymes catalyze all aspects of cell metabolism.
Enzymes are specialized proteins (and in some cases RNA molecules) that act as catalysts in living organisms. They speed up the chemical reactions required for life by lowering the activation energy, all without being consumed in the process.
Ions are inorganic molecules that loosely bond with the enzyme to ensure it can function. By contrast, coenzymes are organic molecules that also loosely bond with and allow an enzyme to do its...
