Protein team produces molecular barrels

Research groups headed by Prof. Dr. Nikolaus Pfanner, Dr. Nils Wiedemann, and Dr. Thomas Becker from the University of Freiburg and their colleagues have demonstrated how molecular protein barrels form in the outer membrane ...

First-ever determination of protein structure with X-ray laser

(Phys.org) —An international team of researchers, including LLNL physicist Matthias Frank and postdoc Mark Hunter, have for the first time used an ultra-intense X-ray laser to determine the previously unknown atomic-scale ...

How cells optimize the functioning of their power plants

Mitochondria, which are probably derived from distant bacterial ancestors incorporated into our cells, have their own DNA. However, we know little about how these organelles, which convert oxygen and consumed nutrients into ...

The role of H3K9 in bringing order to the nucleus

(Phys.org)—Scientists from the Friedrich Miescher Institute for Biomedical Research have elucidated the histone modifications that lead to the sequestration of silent genes at the nuclear periphery. In a study published ...

Study builds on plausible scenario for origin of life on Earth

A relatively simple combination of naturally occurring sugars and amino acids offers a plausible route to the building blocks of life, according to a paper published in Nature Chemistry co-authored by a professor at the University ...
