Posttranslational Covalent Modifications of Proteins focuses on the processes involved in the regulation of protein functions. Partitioned into 21 chapters, the book starts with discussions on the perspectives and prospectives of posttranslational protein modifications; protein phosphorylation and neural and hormonal control of enzymes; and research on the Rous sarcoma virus. The text also looks at studies on phosphorylation, protein kinases, and protein acetylation. The studies show the different reactions of proteins when combined under varying conditions and controlled environments. Schematic representations are presented to validate the processes involved. The book also presents experiments done on Vitamin K-dependent carboxylase from rat liver and cow. Lengthy discussions and diagrams are presented to give credence to the methodologies and results obtained. The text also focuses on studies on enzymatic activities in bacterial toxins and animals tissues. The book is a vital source of data for readers interested in the processes, techniques, and methodologies involved in the modification of proteins.
