How to construct a protein factory

Cells consist of a multitude of molecular structures, some of them exhibiting a staggering complexity. Ribosomes, the protein factories of the cell, belong to the biggest and most sophisticated complexes and are made up of ...

Closing the gate to mitochondria

Eukaryotic cells contain thousands of proteins, which are distributed to different cellular compartments with specific functions. A German-Swiss team of scientists led by Prof. Dr. Bettina Warscheid from the University of ...

Tom22, the bouncer of the mitochondrion

Mitochondria burn sugar and supply the cell with energy. They were long thought to be structures that are relatively independent of the cell. However, Carolin Gerbeth, a PhD student from the trinational research training ...

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 ...

A new glow for electron microscopy

The glowing green molecule known as green fluorescent protein (GFP) has revolutionized molecular biology. When GFP is attached to a particular protein inside a cell, scientists can easily identify and locate it using fluorescence ...
