Attacin

Attacin is a glycine-rich protein of about 20 kDa belonging to the group of antimicrobial peptides (AMP). It is active against Gram-negative bacteria.[1]

Attacin was first discovered in Hyalophora cecropia,[2][3] but is widely conserved in different insects from butterflies to fruit flies.
