abstract：:Intracellular protein degradation is one of the most precisely regulated processes in living cells. The main component of the degradation machinery is the 20S proteasome present in eukaryotes as well as in prokaryotes. We have developed successful purification protocols for the 20S proteasome in its native state using...
