Thermostability and thermoactivity of enzymes from hyperthermophilic Archaea.

Enzymes from hyperthermophilic microorganisms are characteristically thermostable and thermoactive at extremely high temperatures. Information about the basis for the structure and function of these novel proteins is beginning to emerge. However, there are very few generalizations that can be drawn at this point that can be derived from the limited number of studies that have focused on biocatalysis and thermostability at extremely high temperatures.
