We present a comparative analysis of two genome fragments isolated from a diverse and widely distributed group of uncultured euryarchaea from deep-sea hydrothermal vents. The optimal activity and thermostability of a DNA polymerase predicted in one fragment were close to that of the thermophilic archaeon Thermoplasma acidophilum, providing evidence for a thermophilic way of life of this group of uncultured archaea.
我们对从深海热液喷口未培养广古菌的一个多样且分布广泛的群体中分离出的两个基因组片段进行了比较分析。在一个片段中预测的一种DNA聚合酶的最佳活性和热稳定性与嗜热古菌嗜酸嗜热栖热菌相近,这为这组未培养古菌的嗜热生活方式提供了证据。
