Chapter 8.5, Problem 3R

Summary Introduction

To review:

The mechanism that can be used to investigate whether the enzyme catalase has a nonallosteric or the allosteric mechanism of action and whether pollutants that inhibit the catalase enzyme act as noncompetitive or competitive inhibitors.

Introduction:

An allosteric enzyme has a quaternary structure of the protein. The quaternary structure of the protein has many subunits that are attached to one another with the help of disulfide and other noncovalent forces of attraction. Since there are multiple subunits of proteins, each unit has many active sites. The active sites of the proteins are those at, which the substrates binding takes place. In a nonallosteric protein or enzyme, there is only one active site that binds to the substrate.
