title: A novel antimicrobial peptide from the sea hare Dolabella auricularia.
abstract: The sea hare Dolabella auricularia is a marine shell-less gastropod. Four cytotoxic glycoproteins named dolabellanin A, C, E and P were found in the animal previously. An antimicrobial factor was newly isolated from the sea hare's body-wall including skin and mucus. This factor is a novel peptide which consists of 33 amino acid residues, and is called dolabellanin B2. Dolabellanin B2 was cytotoxically effective against some pathogenic microorganisms at a concentration of 2.5-100 microg/ml.
