- 摘要:
- 从大豆品种天隆1号的叶片中克隆GmNup96基因的cDNA序列,对其编码的氨基酸序列、蛋白质理化性质、一级结构、二级结构、亚细胞定位等进行了生物信息学分析。结果表明:GmNup96基因编码1 022个氨基酸,为具有一定亲水能力的酸性蛋白,不具有信号肽,相对分子量为116-199 7 kDa;二级结构预测结果显示,GmNup96序列存在α-螺旋(46.87%)、无规则卷曲(26.32%)、延伸链(17.03%)和β-转角(9.78%),并无其它二级结构;系统进化树分析表明,大豆-GmNup96-基因与野生大豆、芸豆、绿豆、红小豆之间的亲缘关系更近。
- Abstract:
- The cDNA of GmNup96 gene in Tianlong 1 was cloned, and its bioinformatics character was analyzed.The results showed that the gene encoded a 116-199 7 kDa protein with 1 022 amino acids ,which was a hydrophilic protein without signal peptide, and the GmNup96 protein contained a conserved autoproteolytic peptidase domain in the N terminus. Through the secondary structure prediction, GmNup96 protein contained alpha-helix(46.87%), beta turn ( 9.78%), extended strand(17.03%) and random coil (26.32%) Phylogenetic analysis of GmNup96 and its homologs with different plant species were conducted by the software MEGA 5-1.The results showed that GmNup96 from Glycine max were near with-Glycine soja, Phaseus vulgaris, Vigna radiata var. radinta and Vigna angularis in genetic relationship
