[[Proteasome]] (PRTS) are large protein complexes which degrade unneeded proteins into small polypeptides. The 26S PRTS is composed of a central 20S core particle which contains 4 stacked rings each with several members and two 19S caps. The core particle two outer rings contain 7 α subunits which form the PRTS gate. The two inner rings contain 6 β subunits with protease activity. The 19S cap is composed of a base with 10 proteins six of which are ATPases and a lid which contains 9 proteins which bind polyubiquitin.

Proteasome (PRTS) are large protein complexes which degrade unneeded proteins into small polypeptides. The 26S PRTS is composed of a central 20S core particle which contains 4 stacked rings each with several members and two 19S caps. The core particle two outer rings contain 7 α subunits which form the PRTS gate. The two inner rings contain 6 β subunits with protease activity. The 19S cap is composed of a base with 10 proteins six of which are ATPases and a lid which contains 9 proteins which bind polyubiquitin.
