Question
Chapter 12, Problem 17E
Summary Introduction
To explain: The way in which diisopropylphosphofluoridate (DIPF) affects the apparent KM and Vmax of a sample of chymotrypsin.
Concept introduction: KM is the Michaelis-Menten constant. Vmax is the maximum velocity with which the enzyme catalyzes the reaction. Diisopropylphosphofluoridate (DIPF) reacts only with chymotrypsin (Ser 195 amino acid residue) that helped to identify the active site Ser of the enzyme chymotrypsin.

What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
