In studying the mechanism of serine proteases, scientists A and B introduce mutations into the enzymes and monitor the resulting enzyme activity. One

mutation changes the serine of the catalytic triad to cysteine. (10 points)

a. Scientist A thinks this mutation will increase the activity of the enzyme.

Briefly explain the reasoning behind scientist A’s hypothesis.

b. Scientist B thinks this mutation will reduce the activity of the enzyme.
