Answer:
O Gln replaced by Glu or Asn
Explanation:
- Gln replaced by Glu or Asn, is a non-conservative substitution. Gln has a much shorter side chain or R-group than Glu or Asn. Additionally both Glu and Asn R-groups are polar and negatively charged while Gln is non-polar.
- In a protein, replacement with Glu or Asn would greatly destabilize the protein by introducing a charge and disrupting hydrophobic interactions formed between Gln and other non-polar residues.
- By comparing the R-groups of the residues, their length, hydrophobicity, charge and shape. One can predict if the substitution is disruptive or not, if residues are very similar then the interactions that they form are preserved. For example replacing Gln with Ala would be less disruptive.
