You Have Identified a Bacterial Protein That Has Retained the Starting

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.
