Bacterial ribosomes are central to protein synthesis, and their regulation is vital for adaptation to environmental stresses. Under conditions such as nutrient deprivation, cold shock or hypoxia, ...

Led by Northwestern Engineering’s Michael Jewett, researchers created a new version of an engineered tethered ribosome dubbed Ribo-T, which provides a foundation to propel broad, new efforts in ...

Angiogenin is a well-characterized enzyme that has a variety of important roles; it can trigger the growth of new blood vessels, is involved in cell survival, migration, and proliferation, and has ...

Ribosomal RNA (rRNA), made from many copies of ribosomal DNA (rDNA), is the core component that powers ...

The discovery of ribosomes dates back to the 1950s, when George Palade first observed dense particles in the cytoplasm of cells using electron microscopy. These particles were later named "ribosomes" ...

Scientists report a method for stable attachment of peptides to tRNAs, which has allowed them to gain new fundamental insights into ribosome function by determining the atomic-level structures of ...

Researchers have identified a four-protein complex that appears to play a key role in generating ribosomes -- organelles that serve as protein factories for cells -- as well as a surprising part in ...

A team led by UT Southwestern Medical Center scientists has identified a specific stage of neurodevelopment when differentiating neural cells produce fewer ribosomes, which are responsible for making ...

A new technique reveals ribosome cooperativity, providing new insights into protein production. Researchers from Marvin Tanenbaum’s group at the Hubrecht Institute (Utrecht, Netherlands) have ...

Memphis, Tenn.—April 5, 2023) Scientists at St. Jude Children’s Research Hospital revealed that human ribosomes decode messenger RNA (mRNA) 10 times slower than bacterial ribosomes, but do so more ...

Proteins are the infinitely varied chemicals that make cells work, and science has a pretty good idea how they are made. But a critical aspect underlying the machinery of protein manufacture has long ...
