Which of the following is NOT true?

Protein re-folding may be ATP-driven through chaperones.

Polyubiquitylation of a protein targets a protein to the lysosome for destruction.

Unfolded or misfolded proteins may be either re-folded or destroyed.

Protein re-folding may be spontaneous.

Polyubiquitination is the process of adding ubiquitin to a protein, known as ubiquitylation.

Polyubiquitination of a protein generally marks a protein for destruction by 26S proteasome.
