Results After screening, 59 subtracted library clones were isolated which were specific for strain VIB72, and the DNA sequences of these clones were determined. Seventeen fragments showed high homology to the genes of known functions in other bacteria. This includes soluble lytic murein transglycosylase, mobilization protein, transposase (IS66), resistance-related protein (metallo-beta-lactamase and acetyltransferase family), toxin protein (DT-201 and alveicin A immunity protein), ATP-dependent endonuclease of OLD family like protein, SocE and GTP-binding protein HflX (high frequency of lysogenization).

通过对差减文库筛选，分离到59个对菌株VIB72的克隆，并对这些克隆的DNA序列进行了测定。17个基因片断与其它细菌的已知功能的基因有较高的同源性，其中包括可溶性溶胞壁质转糖基酶、转移蛋白MobA和MobC、转座子IS66、抑制相关蛋白（金属β-内酰胺酶和乙酰转移酶家族）、毒素蛋白（DT-201和alveicin A免疫蛋白）、与OLD 家族相似的ATP依赖性核酸内切酶以及SocE 和GTP结合蛋白HflX。

采用含HCV5非编码区(5NCR)缺失突变的重组质粒5T1d，将其目的基因亚克隆到体外转录载体pCDNAⅠ多克隆位点上，获得转录重组体5T1d。

The gene of transglutaminase was amplified from the chromosome of Bacillus subtilis DB403 by PCR and translationally fused with thioredoxin gene in the plasmid pET32a to achieve the expression vector pET32-BTGase.

利用PCR技术，从枯草杆菌DB403染色体上扩增出谷氨酰胺转胺酶基因，将其克隆到大肠杆菌载体pET32a中，成功构建谷氨酰胺转胺酶表达载体pET32-BTGase，并转化大肠杆菌BL21 (DE3)。
