Chapter 6, Problem 5P

(a)

Summary Introduction

To determine: The distance (Å) between ${\text{Arg}}^{145}$ and ${\text{Glu}}^{270}$ if carboxypeptidase chain were a perfect alpha-helix.

Introduction: Enzyme contains an active site, a region of enzyme where substrate binds. After binding of enzyme with substrate, enzyme-substrate complex is formed and initiates rate of chemical reaction.

(b)

Summary Introduction

To explain: How the two amino acids residues that can catalyze a reaction that occurs in space of few angstroms.

Introduction: Amino acids are the building blocks of proteins. It is an organic compound that contains an amine group and carboxyl group along with a function R group. It is involved in the regulation of several cellular processes in the body.
