an important step towards the development of new antimicrobial agents. Leucine zipper
sequence has been implicated in cytotoxic activity of naturally occurring antimicrobial
peptides; moreover, this motif has been utilized for the design of novel antimicrobial
peptides with modulated cytotoxicity. To understand further the impact of substitution of
amino acids at 'a'and/or 'd'position of a leucine zipper sequence of an antimicrobial peptides …
