Proteasome

Function 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 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. For more details see 3unb. Structural highlights The core particle two outer rings contain 7 α subunits (Y7, Y13, PRE6, PRE5, PUP2, C1, C7-α) which form the PRTS gate. The two inner rings contain 7 β subunits (PRE2, PRE4, PRE3, PUP1, PUP3, C5, C11) with protease activity. . of chain H. .
