Question

1. Consider a mutant form of alanine racemase that has an ionic interaction between the side chains of an aspartic acid and an arginine when the protein is at pH 7.4. Assuming all other conditions remain constant, how would changing the arginine to lysine affect the stability of the protein?

Select one:

a. It would increase the stability

b. It would have no or very little effect on the stability

c. It would decrease the stability

Answer 1

option C is correct

c. It would decrease the stability
