Latest Ribosomal protein Stories

Ribosomes, the cellular machines that build proteins, are themselves made up of dozens of proteins and a few looping strands of RNA. A new study, reported in the journal Nature, offers new clues about how the ribosome, the master assembler of proteins, also assembles itself. "The ribosome has more than 50 different parts – it has the complexity of a sewing machine in terms of the number of parts," said University of Illinois physics professor Taekjip Ha, who led the research with U. of...

Naked Mole Rat Longevity Perfect Proteins

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Rochester believe they have discovered the secret behind the longevity of the world’s longest-lived rodent: the creatures produce better protein than other members of their order. Naked mole rats, which typically live approximately 30 years and tend to remain healthy until their final days, possess a unique mechanism for building proteins, according to a recently-published study from research...

Synthetic biology technology could lead to new antibiotics, modified protein-generators Synthetic biology researchers at Northwestern University, working with partners at Harvard Medical School, have for the first time synthesized ribosomes -- cell structures responsible for generating all proteins and enzymes in our bodies -- from scratch in a test tube. Others have previously tried to synthesize ribosomes from their constituent parts, but the efforts have yielded poorly functional...

Proteins, the workhorses of the body, can have more than one function, but they often need to be very specific in their action or they create cellular havoc, possibly leading to disease. Scientists from the Florida campus of The Scripps Research Institute (TSRI) have uncovered how an enzyme co-factor can bestow specificity on a class of proteins with otherwise nonspecific biochemical activity. The protein in question helps in the assembly of ribosomes, large macromolecular machines that...

In the beginning — of the ribosome, the cell's protein-building workbench — there were ribonucleic acids, the molecules we call RNA that today perform a host of vital functions in cells. And according to a new analysis, even before the ribosome's many working parts were recruited for protein synthesis, proteins also were on the scene and interacting with RNA. This finding challenges a long-held hypothesis about the early evolution of life. The study appears in the journal PLoS...

As part of a joint research effort with the University of Michigan, scientists from the Florida campus of The Scripps Research Institute have for the first time defined the structure of one of the cell's most basic engines, which is required for cell growth, as it assembles from its components. The study reveals a series of redundant mechanisms that assure production of these critical structures while avoiding any missteps that could lead to their destruction or to the production of incorrect...

A Howard Hughes Medical Institute investigator from Albany, New York, and an HHMI international research scholar from Buenos Aires, Argentina have combined their expertise to identify two peculiar features of the protein-making machinery of the parasite that causes Chagas disease. Their findings could help scientists develop a safe and effective drug for the disease, whose cardiac complications kill up to 30 percent of those infected. The unusual structure of the ribosome, published online...
