Pre-Lecture Question 7 Which of the following describes the action of the 26S proteasome on ubiquitin-tagged proteins? O Both ubquitin and its linked protein are degraded to amino acids, in an ATP-dependent fashion. O Both ubquitin and its linked protein are degraded to peptides of about 8 residues, in an ATP-dependent fashion O Both ubquitin and its linked protein are degraded to amino acids, in an ATP-independent fashion. O The linked protein, but not ubiquitin, is degraded to peptides of about 8 residues, in an ATP-dependent fashion

Explanation / Answer

both ubiquitine and its linked protein are degraded to amino acids , in an ATP dependent fashion.

proteins which are destined to be degraded will first tagged with ubiquitine and then nest will be degraded by 26S proeosome pathway.
