摘要 金属硫蛋白(metallothionein,MT)是一类富含Cys,能够结合重金属的低分子量蛋白质,广泛分布于生物界。在构建好的蜡梅花cDNA文库并进行EST分析的基础上,通过随机克隆测序得到了1个蜡梅金属硫蛋白的cDNA,命名为CpMetallothionein(CpMT)。CpMTcDNA全长为1083bp,基因内部含有一长度为240bp的开放阅读框,可编码79个氨基酸残基。将CpMT插入原核表达载体pET-32a,并转化Origami2感受态细胞。诱导表达产物经SDS-PAGE结果显示,目的蛋白约为30kD。表达的融合蛋白以包涵体和可溶性蛋白2种形式存在,用His-Bind蛋白纯化回收试剂盒对其进行纯化回收,得到了高纯度蛋白,为今后研究奠定基础。 金属硫蛋白(metallothionein,MT)是一类富含Cys,能够结合重金属的低分子量蛋白质,广泛分布于生物界。在构建好的蜡梅花cDNA文库并进行EST分析的基础上,通过随机克隆测序得到了1个蜡梅金属硫蛋白的cDNA,命名为CpMetallothionein(CpMT)。CpMTcDNA全长为1083bp,基因内部含有一长度为240bp的开放阅读框,可编码79个氨基酸残基。将CpMT插入原核表达载体pET-32a,并转化Origami2感受态细胞。诱导表达产物经SDS-PAGE结果显示,目的蛋白约为30kD。表达的融合蛋白以包涵体和可溶性蛋白2种形式存在,用His-Bind蛋白纯化回收试剂盒对其进行纯化回收,得到了高纯度蛋白,为今后研究奠定基础。
