摘　　要：由耐寒微生物产生的适冷酶显示出较高的催化活力 ,并常与热敏感性有关。运用X射线的结晶学理论 ,这一特性已开始逐渐为人所知 ,且控制它们对低温适应能力的机制各不相同。这些酶的应用为生物技术提供了巨大的发展潜力 。Psychrophilic enzymes produced by cold adapted microorganisms display a high catalytic efficiency and are most often, if not always, associated with high thermosensitivity. Using X ray crystallography, these properties are beginning to become understood, and the rules governing their adaptation to cold appear to be relatively diverse. The application of these enzymes offers considerable potential to the biotechnology industry, for example, in the detergent and food industries, for the production of fine chemicals and in bioremediation processes.
