adj.古细菌的
One fusion partner branches from deep within an ancient photosynthetic clade, and the other is related to the archaeal prokaryotes. 例如，在一些基因树中，真核生物与细菌有关，而在另一些基因树中，真核生物则与古细菌有关。
This layer is called mureine or mycoprotein.Around most archaeal cells there is also a layer of special proteins, but these are glycoproteins and are called S-layer. 这些结构特征使酶分子呈松散状态，具有较大的可变性，从而导致酶的稳定性降低。
The characteristic sequence of archaeal promoter-DPE(distal promoter element) was the functional element necessary for thepromoter activity of RM07 in both Archaea (Haloferax volcanif) and Eukarya(Saccharomyces cerevisiae). 嗜盐古生菌启动子特征序列DPE对于RM07片段在嗜盐古生菌和酵母菌中的启动子活性都是必需的功能元件；
Sequencing analysis also revealed that DNA fragment RM07 possessed three consensus sequences of halphillic archaeal promoter DPE structures, which were similar to that of eukaryotic promoter. 在倒置荧光显微镜下观察细胞中绿色荧光蛋白的表达情况来检测片段RM07和RM07c在哺乳动物细胞株中的启动活性。
