Abstract:
Due to their potential application as novel antibiotics, antimicrobial peptides are attracting much attention. Large quantities of highly purified peptides are crucial to basic and clinical studies. Natural resources of antimicrobial peptides are limited and hard to purify, chemical synthesis is of high-cost and unstable, so recombinant expression of antimicrobial peptides is a cost-effective way. Escherichia coli has been the most widely used as host to express antimicrobial peptides with fusion protein, which can not only avoid the lethal effect towards the host, but also protect the peptide from degradation by proteases. Combined with our research, the present article reviews the progress of fusion vector, cleavage methods and optimization options for antimicrobial peptides production with fusion protein in Escherichia coli.
