Comments Information

    • Function

    • The very low antimicrobial potency (MIC>200 µM) against Escherichia coli and Staphylococcus aureus associated with the peptides is probably a consequence of their lack of amphipathicity and reduced cationicity compared with active members of the ocellatin family from related species.
