Pirate viruses caught in their own trap?

In order to infect a host cell and proliferate, some viruses, such as the hepatitis C virus, infiltrate the ribosomes, the molecular machines that assemble the proteins present in each of our cells. Viral ...

Detour leads to antibiotic resistance

Ludwig Maximilian University researchers have used cryo-electron microscopic imaging to characterize the structural alterations in the bacterial ribosome that are required for induction of resistance to the ...

Protein 'rescues' stuck cellular factories

Using a powerful data-crunching technique, Johns Hopkins researchers have sorted out how a protein keeps defective genetic material from gumming up the cellular works. The protein, Dom34, appears to "rescue" protein-making ...

Designer of protein factories exposed

For 10 years, Patrick Cramer and his colleagues at Ludwig-Maximilians-Universitaet (LMU) in Munich have probed the structure of RNA polymerase I, a crucial cog in the machinery of all cells. Now they unveil ...

Piloting ribosomes past proline pairs

Certain proteins are known to require Translation Factor EF-P for their synthesis, and a new study enlarges the size of the set. As some of its members are involved in bacterial pathogenicity, the results ...

How 'junk DNA' can control cell development

Researchers from the Gene and Stem Cell Therapy Program at Sydney's Centenary Institute have confirmed that, far from being "junk", the 97 per cent of human DNA that does not encode instructions for making proteins can play ...

A roundabout route to protein production

Proteins are typically encoded by linear strands of messenger RNA (mRNA). These mRNA molecules are translated into polypeptide chains by ribosomes, with each ribosomal read-through of the mRNA generating ...
