- 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

Organic Chemistry
A protein sample is analyzed by a kjeldahl process during which ammonia is formed. Ammonia
formed is titrated coulometrically with electrogenerated hypobromite (OBr). If the titration is
performed using 19.3 milliamperes current and end point occur at 2 minutes. Calculate the
milligrams of protein present in the sample if one gram of protein nitrogen is contained in each
6.25gof protein (H=1 and N=14).
