Cecropin A (CeA) is a natural linear cationic α-helical antimicrobial peptide (AMP) originally identified in moths (Hyalophora cecropia) and later in pig intestine. Cecropin A contains a strongly cationic region at its N-terminus and a large hydrophobic tail at its C-terminus, which allow its interaction with the microbial membrane, and then cell lysis by pore formation. Cecropin A has a wide spectrum of antimicrobial activities against gram-negative bacteria, gram-positive bacteria, and fungal phytopathogens.  Cecropins constitute a main part of the innate immune system of insects.
