摘要
通过对多能硫杆菌RubiSCO的基因表达分析表明该基因能够在pBR322的P1启动子、pUC19的lac启动子以及pKK223-3的tac启动子的启动下,在大肠杆菌中表达,RubisCO基因片段在pUC19和pKK223-3载体上的表达活性较高。进一步对RubisCO基因表达产物进行了非变性聚丙烯酰胺凝胶电泳,检测到了RubisCO蛋白质带。
The Rubis CO gene of T. versutus has been successfully expressed in E. colt underthe P1(pBR322), lac(pUC19) and tac (pkk223-3) promoters. ms fragment showed high levelastivities in pUC19 and pKK23-3. Nondenaturing PAGE was performed with each crudeextract of E colt JM109 containing RubisCO gene at various vectors. The product of theexpression of T versutus RubisCO gene have been observed on PAGE electrophoresis.
