Chapter 19, Problem 48FB

Summary Introduction

To review:

The blank space in the statement, “A posttranslational modification that directs a polypeptide to a specific site is called a modification.”

Introduction:

Posttranslational modifications (PTMs) rendera more stable functional and structural diversity to the proteins by the addition of a functional group or removal of a portion of the peptide, It also involves processes such as methylation, phosphorylation, acetylation, hydroxylation, ubiquitination, lipidation, proteolytic cleavage of regulatory subunits, orglycosylation.
