[[Proteasome]] (PRTS) are large protein complexes which degrade unneeded proteins into small polypeptides<ref>PMID:22350895</ref>. 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 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. <br /> | [[Proteasome]] (PRTS) are large protein complexes which degrade unneeded proteins into small polypeptides<ref>PMID:22350895</ref>.
