In this report we present phylogenetic tree based on the sequences of FtsZ-proteins of Archaea, Bacteria and Eukaryota. We have analyzed the relative positions of separate sequences and their clusters and their distance to the hypothetical root of phylogenetic tree as well. It has been demonstrated that most of procaryotic and eucaryotic FtsZ-protein sequences are located at the distance of 0.3-0.8 substitutions per site from the hypothetical root of phylogenetic tree. The tubulins are outlined from the root at 7-8 fold larger distances in comparison with the separate sequences. This confirms the slight aminoacid homology between these two groups of cytoskeletal proteins. At the same time the significant similarity between FtsZ-proteins of cyanobacteria and of plant plastids has been shown.
在本报告中，我们展示了基于古菌、细菌和真核生物FtsZ蛋白序列构建的系统发育树。我们分析了各个序列及其聚类的相对位置，以及它们与系统发育树假设根部的距离。结果表明，大多数原核生物和真核生物的FtsZ蛋白序列与系统发育树假设根部的距离为每个位点0.3 - 0.8个替换。与单个序列相比，微管蛋白从根部开始的距离要大7 - 8倍。这证实了这两组细胞骨架蛋白之间轻微的氨基酸同源性。同时，已显示蓝细菌和植物质体的FtsZ蛋白之间存在显著相似性。
