Existing bacteria and archaea still our universal common ancestor’s ribosomal hibernation defense mechanism when nutrients ...

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 ...

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" ...

Now, scientists at the University of Illinois Chicago are the first to report a method for stable attachment of peptides to tRNAs, which has allowed them to gain new fundamental insights into ribosome ...

The blobfish, once considered the ugliest animal in the world, has since had quite the redemption arc. Years after it was ...

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 ...

The ribosome is one of the most iconic machines in molecular biology—a complex structure that reads a recipe written in RNA to assemble amino acid building blocks into new proteins. Ting Zhu of ...

In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first ...

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 ...

Proteins are critical to biology, carrying out many functions and giving rise to crucial structures. These essential molecules are generated by vital, ancient cellular structures called ribosomes ...
