摘要:
The present invention provides methods and compositions for the production of recombinant plasminogen, microplasminogen, and fragments thereof in a duckweed expression system. It is the novel finding of the present invention that a duckweed expression system may be used to produce high levels of plasminogen and microplasminogen. The duckweed-produced plasminogen and microplasminogen can be activated to produce a polypeptide having protease activity. Thus, the invention encompasses methods for the expression of plasminogen, microplasminogen, and fragments thereof in duckweed, duckweed plants that are transformed with expression cassettes for the expression of plasminogen, microplasminogen, and fragments thereof, and nucleic acids comprising nucleotide sequences encoding plasminogen, microplasminogen, and fragments thereof, where these nucleotide sequences are modified to enhance their expression in duckweed. ® KIPO & WIPO 2007
摘要(中):
本发明提供了用于在浮萍表达系统中生产重组纤溶酶原,微量血浆原和其片段的方法和组合物。 本发明的新发现是,浮萍表达系统可用于产生高水平的纤溶酶原和微量淀粉样蛋白。 可以将浮萍产生的纤溶酶原和微量血浆原活化以产生具有蛋白酶活性的多肽。 因此,本发明包括在用于表达纤溶酶原,微量血浆原和其片段的表达盒转化的浮萍,浮萍植物中表达纤溶酶原,微量淀粉样蛋白及其片段的方法,以及包含编码纤溶酶原,微量稀释细胞的核苷酸序列的核酸 及其片段,其中这些核苷酸序列被修饰以增强其在浮萍中的表达。 ®KIPO&WIPO 2007
