摘要:聚合酶链式反应(PCR)扩增枯草芽孢杆菌ATCC21216(His-)编码腺苷磷酸化酶的基因deoD(0.7 kb),测序表明与枯草芽孢杆菌168的deoD同源性为98.7%。将此基因插入质粒pET28a(+)(5.3 kb)中,重组质粒pETdeoD在大肠杆菌BL21(DE3)中实现了表达,表达量占总蛋白的27%。以HPLC方法测定腺苷磷酸化酶的比酶活为每毫克蛋白0.151 U。
The gene deoD(0. 7 kb) of B. subtilis ATCC21216 encoding an adenosine phosphorylase was amplified by polymerase chain reaction(PCR). Results of sequencing showed 98. 7 % similarity to the same gene of B. subtilis 168. Based on DNA recombinant techniques, the gene deoD was cloned into plasmid pET28a(+)(5.3 kb) to generate highly effective E. coli BL21(DE3) strain producing adenosine phosphorylase. Expression of the recombinant protein was 27% of the total protein. Specific activity of the enzyme in crude extract determined by high performance liquid chromatography was 0. 151 U/mg protein.
