You wish to produce a human enzyme, protein A, by introducing its gene into bacteria. The genetically engineered bacteria make l
Blizzard [7]

Answer:

The options A, B, and D are all valid.

Explanation:

  • The reason is that some proteins require molecular chaperones if they are to fold properly within the environment of the cell. In the absence of chaperones, a partially folded polypeptide chain has exposed amino acids that can form non-covalent bonds with other regions of the protein itself and with other proteins, thus causing nonspecific aggregation of proteins.
  • The option A) is correct because the protein you are expressing in bacteria is being made in large  quantities, it is possible that there are not enough chaperone molecules in the  bacterium to fold the protein. Expressing the protein at lower levels might  increase the amount of properly folded protein.
  • The option B) is correct as urea should solubilize the protein and completely unfold it. Removing the urea  slowly and gradually often allows the protein to refold. Presumably, under less  crowded conditions, the protein should be able to refold into its proper  conformation.
  • The option C) is not correct as treating the aggregate with a protease, which cleaves peptide bonds, will probably  solubilize the protein by trimming it into pieces that do not interact as strongly with  one another; however, chopping up the protein will also destroy its enzymatic activity.
  • The option D) is correct because overexpressing chaperone proteins might increase the amount of properly folded protein.
  • The option E) is not correct as heating can lead to the partial denaturation and aggregation of proteins to form a solid gelatinous mass, as when cooking an egg white, and rarely helps solubilize proteins.
