摘要:
The present invention relates to a method for expressing each of peptide antibiotics P5 3 and Anal3 35 having amphiphilicity and showing antibacterial, antifungal and anticancer activities 61, 63, 65, 67, 69, 71, on the microbial surface, using a vector containing outer membrane protein genes (pgsBCA) that are derived from Bacillus sp. strains and involved in the synthesis of poly-gamma-glutamate. Moreover, the present invention relates to lactic acid-forming bacteria having each of the peptide antibiotics P5 15 and Anal3 43 expressed on their surface, and the use thereof. According to the present invention, the peptide antibiotics can be expressed on the surface of various microorganisms transformed with the surface expression vectors. The inventive method for the surface expression of the peptide antibiotics allows the peptide antibiotics to be mass-produced without a purification process. Thus, the inventive method has very high industrial applicability. Further, the present invention can be applied to other peptide antibiotics besides P5 3 and Anal 3 35.

The present invention relates to a surface expression vector having pgsBCA, a gene coding poly-gamma-glutamate synthetase and a method for expression of target protein at the surface of microorganism using the vector. The vector, in which foreign genes are inserted, transforms microorganisms and makes foreign proteins expressed stably on the surface of microorganisms.
摘要:
Expression vectors are described that can efficiently produce virion capsid protein, tumor-associated protein of human papillomavirus on a microbial surface. Bacterial strains harboring such surface display vectors, and the use of the bacterial strains or their extracts or purified products as complex vaccines, are also described. The surface display vectors contain one or more than two genes selected from among pgsB, pgsC and pgsA, encoding a poly-χ-glutamic acid synthetase complex (pgsBCA) of a Bacillus sp. strain, and genes that encode virion capsid proteins, tumor-associated proteins of human papillomavirus, Methodology for preparing the foregoing vectors, vaccines and transformed microorganisms are also described.
