Ppsa and tkta are the key genes in central metabolism of aromatic amino acids biosynthesis . ppsa encoding phosphoenolpyrucate synthetase a ( ppsa ) which catalyzes pyruvate into pep ; tkta encoding transketolase a which plays a major role in erythrose - 4 - phosphate ( e4p ) production of pentose pathway Ppsa基因编码磷酸烯醇式丙酮酸合成酶a ( ppsa ) ，该酶催化丙酮酸合成磷酸烯醇式丙酮酸； tkta基因编码转酮酶a ，该酶在磷酸戊糖途径中生成4 -磷酸赤藓糖起主要作用。
The results showed that the f fragment , 728bp in length , could be a new gene with a little homology to the genes coding for polyketide synthetase or fatty - acid synthetase and the b fragment , about 4kb in length , is inferred to have repeat sequences around tn5 insertion site , in which there is homology to the wa 314 right arm of the high - pathogeniciry island of yersinia enterocolitica . to reveal any pathogenicity of enterobacter cloacae b8 and its mutated strains b8b and b8f to animals , the experiment with mice was carried out 结果显示， f片段长度为728bp ，与现有生物数据库的blast比较分析，发现该序列仅有局部短于1oobp的区域与polyketide合成酶基因或与脂肪酸合成酶基因有低的同源性，推测为一新基因； b片段长约4kb ，序列拼接结果推测靠近tn5插入位点部位有重复序列，对b片段tn5远端的部分序列进行blast比较，发现它与小肠结肠炎耶尔森氏菌的强毒力岛有一定的同源性。
Among the genes , there were genes directly related to liver regeneration : fetuin , cathepsin ; close related to liver function : cytoplamic aspartate aminotranferase , gutathion sulfur transferase ; related to substance and energy metabolism : atp synthetase , ribosomal protein , and related to stress response : haptoglobin , transferrin 这些基因中有和肝再生有直接关系的如：胎球蛋白、组织蛋白酶；和肝脏功能密切相关的如：胞质天冬氨酸转氨酶、谷胱甘肽硫转移酶；与物质能量代谢有关的如： atp合成酶、核糖体蛋白；以及与急相反应有关的如：触珠蛋白、转铁蛋白。
Strain 042bm - x2 was found to contain a single tn5 insertion in the gene smc02682 , which showing a high degree of similarity with the rhizobium tropici gshb gene , encoding the enzyme glutathione synthetase . in our experiment , this gene was demonstrated to be related to salt tolerance . so it is named as rst - 0x2 Rst - 0x1基因的功能未知，而rst - 0x2基因和热带根瘤菌谷胱甘肽合成酶基因gshb有很高的同源性。 pcr扩增得到包含启动子的042bmrst - 0x1和rst - 0x2基因的全长。

Hisityl - trna synthetase catalyzes the aminoacylation of trnahis in the initial step of protein biosynthesis . the involumen of histidyl - trna synthetase in autoimmune diseases is another feature of the enzyme . in studies , it is reported that purified jo - 1 antigen can increase the detection rate of anti - jo - 1 antibody . but it is difficult to obtain a single component by biochemical extraction . genetic engineering can help us to desolve this problem . after looking up mrna sequence encoding histidyl - trna synthetase in genebank , we used rt - pcr technology to gain its full length dna sequence . the vestor ptybllwas used in the construction of expressing vestor . we transformed the jo - 1 gene into er2566 and used this system to express fusion jo - 1 antigen 本实验从人胎盘中提取总rna ，利用rt - pcr技术获得了编码jo - 1的基因整长序列，选用impact - cn系统中的ptyb11载体，构建了jo - 1基因的克隆与表达载体，并转化大肠杆菌er2566 ，经过抗性筛选、分子量大小比较、双酶切鉴定、和pcr鉴定等多种方法验证，筛选出了5个阳性克隆。
