摘要
为构建耐盐的转基因植物提供材料,根据地衣芽孢杆菌Bacillus licheniformisATCC 14580的GbsB基因的核甘酸序列设计1对特异性引物,通过PCR的方法扩增由分离的中度嗜盐菌Bacillus sp.XJ1-05的GbsB基因,经T/A克隆,插入到pBS-T载体上进行序列测序,采用NCBI-BlastX软件在Genbank数据库中进行同源性检索,结果表明:得到的GbsB基因的开放阅读框(ORF)全长为1209bp,编码1个由402个氨基酸残基组成的蛋白质;其与Bacillus licheni-formisATCC 14580的GbsB基因的氨基酸序列同源性高达96%。生物信息学分析表明:该GbsB基因编码蛋白无信号肽,无跨膜区域,高亲水性,有2个乙醇脱氢酶作用位点。
