Gip1 structure places G proteins in lockdown

Heterotrimeric G proteins are important in G protein-coupled receptor signaling, which plays many roles in the detection of various environmental stimuli, including hormones, neurotransmitters, light, smells, and chemical ...

New technique enables spatial separation of peptide structures

A team of scientists at DESY and Universität Hamburg has reached another milestone towards the direct imaging of individual biomolecules: the group led by Jochen Küpper from the Center for Free-Electron Laser Science developed ...

Physicists explain how large spherical viruses form

A virus, the simplest physical object in biology, consists of a protein shell called the capsid, which protects its nucleic acid genome—RNA or DNA.  The capsid can be cylindrical or conical in shape, but more commonly ...

Bacteria: Protein researchers decipher resistance mechanism

Worldwide, resistance to antibiotics is on the rise. In order to understand why bacteria are becoming immune to previously well-functioning drugs, scientists are penetrating ever deeper into the molecular structure of cells. ...
