Moricin is a highly basic antibacterial peptide that was isolated from the silkworm Bombyx mori.[1] It consists of a long alpha-helix with 8 turns from a 42 amino acid sequence over almost the entire protein.[1] The amphipathic N-terminal segment of the alpha- helix is mainly responsible for the increase in permeability of the bacterial membrane which kills the bacteria.[1] Moricin functions as an antibacterial peptide against Gram-positive and Gram-negative bacteria, with its main activity being towards Gram-positive bacteria.[1]
