摘要 [Objective] This study aimed to analyze the bioinformatics information of Betula phatyphylla metallothionein for subsequent investigation of the important func- tions of metallothionein gene. [Method] The physical and chemical properties, trans- membrane domains, hydrophobicity / hydrophilicity, secondary structure, functional domains and functional classification of B. phatyphylla metallothionein were analyzed and predicted using bioinformatics methods and tools. [Result] The relative molecular mass of B. phatyphylla metallothionein is 7.75 kD and isoelectric point is 5.66; there is a strong hydrophobic region in the center of B. phatyphylla metallothionein and hydrophilic regions in both ends; B. phatyphylla metallothionein may be a non-trans- membrane protein and is mainly constituted by random coil without enzymatic activi- ty, suggesting that it belongs to Metallothio_2 protein family. [Conclusion] This study provided reference for further functional research of B. phatyphylla metallothionein gene. [目的]分析白桦金属硫蛋白的生物信息学信息,为后续基因重要功能研究奠定基础。[方法]利用生物信息学方法和工具对白桦(Betula platyphylla)金属硫蛋白(metallothionein,MT)的理化性质、跨膜结构、疏水性/亲水性、二级结构、结构功能域、功能分类进行了分析和预测。[结果]金属硫蛋白的分子量为7.75 kD,等电点为5.66,中部有较强疏水区,而其两端为明显亲水区,其可能为非跨膜蛋白,主要构件为卷曲,属于Metallothio_2蛋白家族。[结论]该研究可为白桦金属硫蛋白基因功能研究提供参考。
