Subunits

Subunits Comment Organism
More the 26 S proteasome is composed of two subparticles, the 20S core protease that compartmentalizes the protease active sites and the 19S regulatory particle that recognizes and translocates appropriate substrates into the core protease lumen for breakdown. The 2.5-MDa core protease-regulatory particle complex is actually a heterogeneous set of particles assembled with paralogous pairs for most subunits, mass spectrometric analysis of the complex, overview Arabidopsis thaliana

General Information

General Information Comment Organism
additional information activity and subunit composition of the 26 S proteasomes in plants, detailed overview. The 26 S proteasome is composed of two subparticles, the 20 S core protease that compartmentalizes the protease active sites and the 19 S regulatory particle that recognizes and translocates appropriate substrates into the core protease lumen for breakdown. A diverse and highly dynamic population of proteasomes is assembled in plants, which may expand the target specificity and functions of intracellular proteolysis, overview Arabidopsis thaliana
