Chapter 19, Problem 73TQ

Summary Introduction

To review:

The incorporation of nonstandard amino acid pyrovaline into an enzyme molecule and the properties of this nonstandard amino acid.

Introduction:

Nonstandard amino acids are those amino acids thatdo not encodefor proteins. Variation in genetic code may lead to incorporation of nonstandard amino acids to polypeptides. This enables the proteins to generate new chemical properties, structures, and functions.
