Protein folding helpers in their natural environment

Scientists from Martinsried and Göttingen have analyzed protein folding helpers, so-called chaperonin complexes, in their natural environment using cryo-electron tomography.   Cryo-electron tomography, or cryo-ET for short, can be used to visualize and analyze cellular structures in their natural environment. Researchers at the Max Planck Institute of Biochemistry (MPIB) in
