Ubiquitinated proteins are proteolytically degraded in an ATP-dependent process mediated by a large (∼2500 kD, 26S) multiprotein complex named the 26S proteasome;

#Unit 1. Molecules and their Interaction Relevant to Biology

A hollow cylindrical core, known as the 20S proteasome, which is covered at one or both ends by a 19S cap.
The yeast 20S proteasome, which is closely similar to other eukaryotic 20S proteasomes, is composed of Ten different types of α-like subunits.
The yeast 20S proteasome, which is closely similar to other eukaryotic 20S proteasomes, is composed of seven different types of α-like subunits and seven different types of β-like subunits.
The α-type subunits and the β-type subunits are structurally similar, only three of the β-type subunits have proteolytic activity.

Choose any one incorrect option.
