This sequence is the primary structure of a protein ; it influences secondary , tertiary , and quaternary structure 这是蛋白质的一级结构,它影响着蛋白质的二级,三级和四级结构。
Although it has predicted that different ftsz families share the same tertinary structure but they also similar to that of tubulin ' s 因此分别就蛋白质的四级结构而言,水稻的ftsz蛋白比衣藻的要复杂。

These results unambiguously demonstrate that a single amino acid residue substitution is sufficient to generate a phenylalanine - insensitive form of arog . furthermore , the mutant a ( l - 15 ) lacking the first fifteen n - terminal amino acid residues exhibits no sensitivity toward phenylalanine in a range of 0 ~ 1 mm phenylalanine 这些结果揭示: 1 ) n一末端在反馈抑制机理中具有重要作用; 2 ) n一末端的缺失使得ar0g紧密二聚体结构解聚,导致四级结构破坏。
In order to check if it is the aim gene , we devised pcr with a new pair of primer , sequenced and registered the product with registration number : af449446 . moreover we forecast and analysis the primary , secondary , tertiary and quaternary structure of the three protein : osftszi , crftszi and crftsz2 which has already cloned by our team before . after that we construct ftsz molecular evolution tree to site them in 又将生物信息学技术同实验技术相结合,针对ftsz保守区设计引物扩增出一条衣藻ftsz片段,进行est搜索、比对、拼接,最终克隆出新基因crftsz1 ;连同本试验室曾经获得的另一个衣藻crftsz2基因进行蛋白质的一、二、三、四级结构预测、分析及比较寻找进化线索,建立了ftsz蛋白的氨基酸进化树作进一步的进化定位。
