论文名称:High-level expression of a soluble snake venom enzyme, gloshedobin, in E-coli in the presence of metal ions 论文类型:期刊论文 发表刊物:BIOTECHNOLOGY LETTERS 收录刊物:Scopus、SCIE、PubMed 卷号:25 期号:8 页面范围:607-610 ISSN号:0141-5492 关键字:Escherichia coli; expression; gloshedobin; thrombin-like enzyme 摘要:The mature gene of gloshedobin, a snake venom thrombin-like enzyme from the snake, Gloydius shedaoensis, was cloned and expressed in strain E. coli BL21(DE3). Having been induced by IPTG, the recombinant gloshedobin was in both soluble and insoluble forms. To avoid inclusion body formation, expression was optimized at 25degreesC. Furthermore, a 50% increase in solubilization of the target protein was obtained by adding 0.1 mM Mg2+ to the medium. The purified recombinant gloshedobin gave a 44 kDa band on SDS-PAGE gel. 发表时间:2003-04-01
