Grammistins are a group of peptides secreted by soapfishes and characterized by its amphiphilic -helical structure. There are four types of Grammistins: Pp1,Pp3, Gs1, and Gs2. Gs 1 and Gs 2 are from Grammistes sexlineatus and Pp 1 and Pp 3 from Pogonoperca punctata (Yokota, Nagashima, and Shiom, 2001). Grammistin-Pp1 is made up of thirteen amino acid residues. Studies showed that Grammistin-Pp1 could interact with phospholipids and influence the permeability of membrane. Sugiyama et al. (2006) reported that the peptide Grammistin-Pp1 is effective on both Gram negative bacteria and Gram positive bacteria, which includes Staphylococcus aureus.
