Biotechnological uses of archaeal extremozymes.
Archaea have developed a variety of molecular strategies to survive the often harsh environments in which they exist. Although the rules that allow archaeal enzymes to fulfill their catalytic functions under extremes of salinity, temperature or pressure are not completely understood, the stability of these extremophilic enzymes, or extremozymes, in the face of adverse conditions has led to their use in a variety of biotechnological applications in which such tolerances are advantageous. In the following, examples of commercially important archaeal extremozymes are presented, potentially useful archaeal extremozyme sources are identified and solutions to obstacles currently hindering wider use of archaeal extremozymes are discussed.
