Surface expression vector using two kinds of promoters derived fromfor concurrently expressing two target proteins and method for expressing proteins on microbial surface by using same

Abstract

Provided is a vector capable of co-expressing two different target proteins on the microbial surface using two promoters derived from, and a method of expressing target proteins on the microbial surface using the vector. The vector containing foreign genes inserted therein is transformed into a microorganism, and allows different foreign proteins to be stably expressed on the surface of the microorganism. Furthermore, provided is a surface expression vector containing the gene pgsA encoding a poly-gamma-glutamate synthetase complex, and a method of expressing a target protein on the microbial surface using the vector. The vector containing foreign genes inserted therein is transformed into a microorganism, and allows the foreign proteins to be stably expressed on the surface of the microorganism.
