You Have Identified a Bacterial Protein That Has Retained the Starting

question 45

Multiple Choice

You have identified a bacterial protein that has retained the starting fMet in its protein sequence. Which of the following is likely true of this protein?

• A)It is likely nonfunctional, since bacteria use posttranslational cleavage of fMet to make functional proteins.
• B)It will show improper protein sorting and will likely remain in the ER.
• C)It will be not be able to be chemically modified, so it will be sent to the Golgi for secretion.
• D)It will be a functional bacterial protein, since all functional proteins must begin with fMet.
• E)It will likely form a disulfide bond with a second peptide chain, forming a protein complex.
