Proteasome assembly: biting the hand.
Proteasome assembly is regulated to ensure the enzyme is inactive until its active sites are compartmentalized within an interior aqueous chamber. In yeast, this depends on a dedicated chaperone that is trapped within the nascent proteasome, and degraded on maturation of the proteolytic subunits.
