The change in the amino acid sequence illustrated in Figure 1 caused a change in the shape of Receptor X. Based on the R groups of the original and substituted amino acids, explain why Receptor X changed shape.
Understand the Problem
The question is asking for an explanation of how changes in the R groups of amino acids cause a change in the shape of Receptor X, which relates to protein structure and function.
Answer
The change from charged/hydrophilic to uncharged/hydrophobic R-groups altered the shape of Receptor X.
Receptor X changed shape because the substitution replaced amino acids with charged or hydrophilic R-groups with ones that have uncharged or hydrophobic R-groups. This alters the interactions within the protein, affecting its overall shape and structure.
Answer for screen readers
Receptor X changed shape because the substitution replaced amino acids with charged or hydrophilic R-groups with ones that have uncharged or hydrophobic R-groups. This alters the interactions within the protein, affecting its overall shape and structure.
More Information
The properties of amino acid side chains (R-groups) greatly influence protein folding and function. Hydrophobic interactions drive nonpolar side chains to interior positions, while charged or polar side chains prefer surface locations or interactions with other polar molecules.
Tips
A common mistake is not considering the impact of hydrophobic interactions and hydrogen bonds on protein structure.
