DRAMP02768

DRAMP02768 chydropathy plot
    • Function

    • Has strong cytotoxic and hemolytic activities. Is more potent against mononuclear leukocytes than against granulocytes. The synthesized peptide 57-76 shows a potent and broad spectrum antimicrobial activity against both Gram-positive and Gram-negative bacteria, and also against the fungus C. albicans. Adopts an alpha-helical structure.
    • Tissue specificity

    • Expressed by the venom gland.
    • Allergenic properties

    • Causes an allergic reaction in human.
