Much is being learned from the study of thermophiles, especially our understanding of biology at the molecular level and the genetic mechanisms that permit adaptation. Included in this volume is a discussion of protective strategies of thermophiles, including their thermostability, which allow them to maintain functional proteins. It also investigates whether hyperthermophiles employ protein phosphorylation-dephosphryation as a molecular regulatory mechanism, and provides significant clues regarding the synthesis of protein. By studying this extreme example, its subtle, yet exaggerated response mechanisms, and its development over the course of many short-lived generations, we may begin to understand the mechanisms in diseases linked to improper protein folding, and also begin to more fully understand the ingenious design of DNA, and all that such an understanding implies regarding the survival of human life in a rapidly changing environment.
