SURFACE EXPRESSION VECTOR USING TWO KINDS OF PROMOTERS DERIVED FROM LACTOBACILLUS CASEI FOR CONCURRENTLY EXPRESSING TWO TARGET PROTEINS AND METHOD FOR EXPRESSING PROTEINS ON MICROBIAL SURFACE BY USING SAME

摘要

The present invention relates to a vector using two promoters derived from Lactobacillus for expressing two target proteins on a microbial surface and a method for concurrently expressing the target proteins on a microbial surface by using the same vector. The vector having foreign genes inserted thereinto is transformed into a microbe and allows the different foreign proteins to be stably expressed on the surface of the microbe. Furthermore, the present invention relates to a surface expression vector carrying pgsA and a method for expressing target proteins on a microbial surface, wherein a gene coding for poly-gamma glutamate synthase and the vector are used. The vector having foreign genes inserted thereinto is transformed into a microbe and allows the different foreign proteins to be stably expressed on the surface of the microbe.
