摘要

乳铁蛋白肽是乳铁蛋白在酸性条件下经胃蛋白酶裂解,从N端释放的具有两亲性的阳离子多肽,具有广谱抗菌活性。目前,乳铁蛋白肽主要是通过水解乳铁蛋白来获得,无法大规模生产,基因工程技术将是大规模生产乳铁蛋白的最佳途径。文中对乳铁蛋白肽的抑菌活性及其转基因生产技术(包括表达系统的选择与比较,基因工程菌发酵液中乳铁蛋白肽的分离和纯化等)进行了简要的综述。

Abstract

Lactoferricin is an amphipathic,cationic peptide with stronger anti-microbial activity than lactoferrin.It was mainly generated by the pepsin-mediated digestion from N-terminal of lactoferrin in small scale,Genetic engineering will be the best method to produce lactoferricin.This paper gives an overview on antimicrobial activities of lactoferricin and its production by genetic engineering including the selection and comparision of expression systems,isolation and purification of lactoferricin from the fermented broth of genetic engineering bacteria.
