Gramicidin s - insect
WebGramicidin S (Figure 11.10) is a cyclic decapeptide natural product whose history spans more than seventy years.It displays antibiotic activity against both Gram-negative and Gram-positive bacteria by interacting with the bacterial lipid bilayer [52].This interaction is closely linked to the structure of gramicidin S—its amphipathic properties are enhanced by its 3 …
