DRAMP01613

    • Function

    • The aurein antibiotics show more activity towards gram-positive than gram-negative pathogens. Probably acts by disturbing membrane functions with its amphipathic structure. Shows anticancer activity.
    • Tissue specificity

    • Expressed by the skin dorsal glands.
