proteosome
The 20S proteosome has 28 protein subunits arranged as an (a1 - a 7, b1 - b 7) 2 complex in four stacked rings. The interior of the complex has the active sites. The b -type subunits are synthesized as pro-proteins and are proteolytically cleaved before assembly. Nomenclature is complex:
