独特的Thr15氨基酸残基发生O-糖基化，增强了对革兰氏阴性菌的抗菌活性。盐会影响其活性。莱博辛能增加囊泡的通透性，并可能与天蚕素D协同作用。更新于2009年12月。莱博辛4具有抗菌活性。莱博辛4在家蚕（Bombyxmori）中被发现。

The unique Thr15 residue is O-glycosylated and enhances antibacterial activity against Gram-negative bacteria. Salts influences its activity. Lebocins increase vesicle permeability and may work synergistically with cecropin D. Updated 12/2009. Lebocin 4 has Antibacterial activity. Lebocin 4 was found in silk moth, Bombyx mori.
