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.
古生菌已经发展出多种分子策略来在它们所处的通常较为恶劣的环境中生存。尽管使古生菌酶在极端盐度、温度或压力条件下发挥催化功能的规则尚未完全明确,但这些嗜极端酶(极端微生物酶)在面对不利条件时的稳定性,已促使它们在各种具有此类耐受性优势的生物技术应用中得到应用。以下将介绍具有商业重要性的古生菌极端酶的实例,确定潜在有用的古生菌极端酶来源,并讨论目前阻碍古生菌极端酶更广泛应用的障碍的解决方案。
