Surface expression method of peptides P5 and Anal3 using the gene encoding poly-gamma-glutamate synthetase
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.
摘要（中）：

本发明涉及在微生物表面上表达具有两亲性的肽抗生素P5 3和Anal335各自表现出抗菌，抗真菌，抗癌活性的方法， 来自芽孢杆菌属的膜蛋白基因（pgsBCA） 菌株并参与了聚-γ-谷氨酸的合成。 此外，本发明涉及在其表面表达的各肽抗生素P515和Anal343各自的乳酸形成细菌及其用途。 根据本发明，肽抗生素可以在用表面表达载体转化的各种微生物的表面上表达。 肽抗生素表面表达的本发明方法允许肽抗生素在没有纯化过程的情况下批量生产。 因此，本发明的方法具有非常高的工业实用性。 此外，除了P5 3和Anal 3 35之外，本发明可以应用于其它肽抗生素。
