    • The present invention relates to a plasmid (pHCE-FOREX) functioning as both a T-vector and an expression vector, which is produced by imparting a T-vector function to an HCE promoter derived from a constitutive high-level expression vector and can express a target protein in a simple and rapid manner. Also, the present invention relates to an expression vector having the target gene inserted into the plasmid, and the expression of the target gene using the same. The plasmid of the present invention can be converted into a vector that expresses the target protein by one-step T-vector cloning in a simple and rapid manner. The plasmid converted into the expression vector does not require a re-transformation step and allows the high-level expression of the target protein only by the culturing of transformed E. coli without the addition of an expensive inducer. Thus, according to the present invention, expression plasmids for large amounts of target genes can be produced at the same time, so that the present invention will be very efficient in establishing expression systems for certain genomes and gene groups.
    • 本发明涉及用作T载体和表达载体两者的质粒(pHCE-FOREX),其通过赋予来自组成型高水平表达载体的HCE启动子产生T载体功能而产生,并可表达 目标蛋白以简单快速的方式。 此外,本发明涉及将靶基因插入质粒的表达载体,以及使用该表达载体的靶基因的表达。 本发明的质粒可通过简单快速的一步T载体克隆转化为表达靶蛋白的载体。 转化成表达载体的质粒不需要再转化步骤,并且仅通过培养转化的大肠杆菌而不添加昂贵的诱导物才允许靶蛋白的高水平表达。 因此,根据本发明,可以同时生产大量靶基因的表达质粒,从而本发明在建立某些基因组和基因组的表达系统方面将非常有效。
