Abstract

Background: Traditional antimicrobial agents are losing their efficiency as microbial resistance increases. Thus, developing antimicrobial peptides (AMPs) can assist as an alternative approach. For AMPs, the hypothesis mode of action is involved in pore formation within the lipid membrane, thereby leading to cell death. In this study, interaction between Bactenecin and 1-palmitoyl-2-oleoylsn- glycero-3-phosphatidylcholine (POPC) was studied. 
Methods: For this purpose, two systems, Bactenecin in water and Bactenecin in POPC were treated by 50 ns of molecular dynamic simulation and data were compared with those of free POPC. 
Results: The results suggest that the interaction between Bactenecin and bilayer membrane cause some disorder and more instability along with little compactness of bilayer. The hydrogen bond between peptide and heads of lipid components may is main reason of membrane compactness. The results can provide some information on how to Bactenecin or other such peptides affect bio-membranes.
