- Can a mutation change a protein’s tertiary structure without changing its primary structure? Explain your answer.arrow_forwarda. Suppose that the R group of a histidine residue in a protein in its native tertiary structure is buried in the interior of the protein and is involved in a salt bridge (ionic interaction) with an oppositely charged residue. Unfolding the protein exposes both of the charged groups to water. Would you expect the pKa of the His R group (side chain) in the native protein to be a) higher or b) lower than the pKa of the same residue in the unfolded protein? Why? b.
