| 摘 要： | 用生物信息分析方法对已在GenBank上注册的拟南芥等13种植物金属硫蛋白MT2的氨基酸序列与组成、亚细胞定位、跨膜区与信号肽、疏水性／亲水性、蛋白质二、三级结构以及功能等进行分析与预测。结果表明，植物MT2主要位于叶绿体中，无信号肽，是非跨膜的亲水性蛋白，不规则卷曲是其蛋白质二级结构的主要结构元件，无功能结构域。这一结果可为植物MT2深入的结构与功能分析及利用提供进一步的信息与参考。

| Abstract: | Amino acids composition,sub - cell location, signal peptides and tran - membrane regions, hydrophobicity/hydrophilicity, secondary and tertiary structure and functions of thirteen kinds of plant metallothioneins（MT2）including Arabidopsis thaliana registered in GenBank were analyzed and predicted by bioinformatics method. Results shows that plant MT2 mainly locates in the chloroplast, it has no signal peptides and is a non- transmembrane hydrophilic protein, irregularity curl is the main components of its secondary structure and has no function domain. The work would be of great information and values for the further structure and function study and utilization of plant MT2. |
