N2 - Background: ATPase subunits mediate 26 S proteasome assembly and function. Results: Defective ATP binding by some ATPase subunits inhibits proteasome assembly, and proteasomes harboring an ATP binding-defective subunit are impaired for proteolysis, substrate-stimulated gating, and ATPase activity. Conclusion: The proteasome requires normal ATP binding for assembly and function. Significance: Protein substrates promote their own degradation by inducing ATP-dependent proteasome functions.
