    • A novel constitutive strong promoter is provided to express effectively a target protein on the surface of a microorganism transformed by an expression vector containing the promoter, so that the transformed microorganism is useful as a vaccine carrier. An aldolase promoter isolated from Lactobacillus casei has the nucleotide sequence of SEQ ID NO:1. A microorganism surface expression vector contains the aldolase promoter, polygammaglutamic acid synthetase complex gene selected from pgsA, pgsB and pgsC and a gene encoding a target protein. A method for producing a microorganism vaccine comprises the steps of: (a) transforming a microorganism with the microorganism surface expression vector and culturing the transformed microorganism to express an antigen on the surface of transformed microorganism; and (b) recovering the antigen surface-expressed microorganism, wherein the microorganism is a lactic acid bacterium.

    • PURPOSE: A plasmid having a function of T-vector and expression vector, and expression of a target gene using the same plasmid are provided, which plasmid is easily converted to T-vector, and allows for expression of the target protein through one cloning step. CONSTITUTION: The plasmid pHCE-ROREX having a function of T-vector and expression vector comprises two recognition sites where the T-vector is able to be cloned downstream of a promoter in a vector pHCE which continuously highly expresses a target protein without limitation by a host cell, wherein the recognition site is selected from HphI, MboII, AspEI and XcmI; and a polynucleotide is inserted between two recognition sites. An expression vector is prepared by digesting the plasmid with the recognition enzyme to remove the polynucleotide inserted, and inserting a target gene into the polynucleotide removed site in the plasmid. The method for expression of the target gene comprises transforming a bacterium with the expression vector containing the target gene, and culturing the transformed bacterium.
    • 目的:提供具有T载体和表达载体的功能的质粒和使用相同质粒的靶基因的表达,该质粒易于转化为T载体,并且允许通过一个克隆步骤表达靶蛋白 。 构成:具有T载体和表达载体的功能的质粒pHCE-ROREX包含两个识别位点,其中T载体能够克隆在载体pHCE中的启动子下游,其不断高度表达靶蛋白,而不受 宿主细胞,其中所述识别位点选自HphI,MboII,AspEI和XcmI; 并且在两个识别位点之间插入多核苷酸。 通过用识别酶消化质粒以除去插入的多核苷酸并将靶基因插入质粒中的多核苷酸去除部位来制备表达载体。 用于表达靶基因的方法包括用含有靶基因的表达载体转化细菌,并培养转化的细菌。
