Question

Choose the statements that correctly describe the structure and function of proteasomes:

(1) Proteasomes would not be expected to use ATP to degrade small, unfolded peptides.

(2) Ubiquitin is hydrolyzed by the 19S complex and is then reformed using the recycled amino acids.

(3) The peptide products are hydrolyzed in the cytoplasm to yield free amino acids.

(4) Proteasomes degrade proteins to small peptides.

(5) The proteolytic sites of the proteasome are located at the middle of the 20S core.

(6) The 26S proteasome unit is composed of a 12S component and a 14S component.

NOTE: The answer consists of more than just one of the six statements above.
