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.
蛋白酶体的组装受到调控,以确保该酶在其活性位点被分隔在内部水相腔室中之前保持无活性。在酵母中,这依赖于一种专门的伴侣蛋白,它被困在新生的蛋白酶体中,并在蛋白水解亚基成熟时被降解。
