adj.古細菌的

One fusion partner branches from deep within an ancient photosynthetic clade, and the other is related to the archaeal prokaryotes. 例如，在一些基因樹中，真核生物與細菌有關(guān)，而在另一些基因樹中，真核生物則與古細菌有關(guān)。

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. 這些結(jié)構(gòu)特征使酶分子呈松散狀態(tài)，具有較大的可變性，從而導(dǎo)致酶的穩(wěn)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). 嗜鹽古生菌啟動子特征序列DPE對于RM07片段在嗜鹽古生菌和酵母菌中的啟動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. 在倒置熒光顯微鏡下觀察細胞中綠色熒光蛋白的表達情況來檢測片段RM07和RM07c在哺乳動物細胞株中的啟動活性。
