Prokaryotic proteasomes are a rare breed: only the Archaea and a few members of the Actinomycetes have been shown to possess a proteasome. But now, this exclusive club has a new member — two ...

The proteasome, the cell's garbage disposal mechanism, usually breaks down proteins into smaller pieces and recycles some of the pieces. That is still largely the case, but researchers at Johns ...

MiR-29b replacements also decreased PA200 association with proteasomes, reduced the proteasome’s peptidase activity and inhibited ornithine decarboxylase turnover, a proteasome substrate ...

The disposal takes place in so-called proteasomes, which are a cellular waste disposal factory. Before the proteins are fed into this factory, the Ubiquitin chains are split off and the chains must be ...
