Anti-Microbial Peptides: The Importance of Structure-Function Analysis in the Design of New AMPs
In recent years the rapid emergence of drug resistant microorganisms has become a major health problem worldwide. The number of multidrug resistant (MDR) bacteria is in a rapid increase. Therefore, there is an urgent need to develop new antimicrobial agent that is active against MDR. Among the possible candidates, antimicrobial peptides (AMPs) represent a promising alternative. Many AMPs candidates were in clinical development and the Nisin was approved in many food products. Exact mechanism of AMPs action has not been fully elucidated. More comprehensive of the mechanism of action provide a path towards overcoming the toxicity limitation. This chapter is a review that provides an overview of bacterial AMPs named bacteriocin, focusing on their diverse mechanism of action. We develop here the structure–function relationship of many AMPs. A good understanding of AMPS structure–function relationship can helps the scientific in the conception of new active AMPs by the evaluation of the role of each residue and the determination of the essential amino acids for activity. This feature helps the development of the second-generation AMPs with high potential antimicrobial activity and more.
