Which of the following does NOT occur during ubiquitination degradation of proteins? A)Multiple ubiquitinations may occur on a protein substrate. B)Ubiquitin-protein ligase (E₃)transfers ubiquitin to free amino groups on the protein. C)E₃ selects a protein for degradation by the nature of the C-terminal amino acid. D)Ubiquitin-carrier protein (E₂)picks up ubiquitin.

Question

Quizplus · Accepted Answer

The selection of a protein for degradation by the nature of the C-terminal amino acid does not occur during ubiquitination degradation of proteins. Multiple ubiquitinations may occur on a protein substrate, ubiquitin-carrier protein picks up ubiquitin, and ubiquitin-protein ligase transfers ubiquitin to free amino groups on the protein.
