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, ...
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 ...
Many fine-scale features of ribosomes have been explained in terms of function, revealing a molecular machine that is optimized for error-correction, speed and control. Here we demonstrate ...
Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...
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 ...
Researchers have developed a new microscopy technique to observe how ribosomes function in cells. With this method, they can monitor individual ribosomes as they convert mRNA into proteins. The ...
Under stress, animal cells pair inactive ribosomes into RNA-linked disomes. A ribosomal RNA “kissing loop” joins them, protecting ribosomes and reducing protein synthesis to conserve energy.<br /> ...
Inside tiny cellular machines called ribosomes, chains of genetic material called messenger RNAs (mRNAs) are matched with the corresponding transfer RNAs (tRNAs) to create sequences of amino acids ...
Proteins are absolutely essential for the survival of organisms; they carry out many functions that are critical to life. Something needs to build all of those proteins from their basic components.
Researchers from the Stowers Institute for Medical Research have discovered a new function of ribosomes in human cells that may show the protein-making particle's role in destroying healthy mRNAs, the ...
Aging leads to a decline in cellular fitness and loss of optimal protein function. The mechanisms underlying how aging causes proteins to aggregate have not been fully understood. Using models of ...
Inside tiny cellular machines called ribosomes, chains of genetic material called messenger RNAs (mRNAs) are matched with the corresponding transfer RNAs (tRNAs) to create sequences of amino acids ...
