摘要：

Only in the last decade have microorganisms been discovered which grow near or above 100-degrees-C. The enzymes that are formed by these extremely thermophilic (growth temperature 65 to 85-degrees-C) and hyperthermophilic (growth temperature 85 to 110-degrees-C) microorganisms are of great interest. This review covers the extracellular and intracellular enzymes of these exotic microorganisms that have recently been described. Polymer-hydrolysing enzymes, such as amylolytic, cellulolytic, hemicellulolytic and proteolytic enzymes, will be discussed. In addition, the properties of the intracellular enzymes involved in carbohydrate and amino-acid metabolism and DNA-binding and chaperones and chaperone-like proteins from hyperthermophiles are described. Due to the unusual properties of these heat-stable enzymes, they are expected to fill the gap between biological and chemical processes.
