DRAMP02639

Comments Information

    • Function

    • Has antimicrobial activities against bacteria and fungi (By similarity).

    • Subunit structure

    • Forms a cyclic homodimer; disulfide-linked (By similarity).

    • PTM

    • This is a cyclic peptide (By similarity).

    • Caution

    • The mature 9-residue peptide is expected to be found in 18-residue cyclopeptides produced by combinatorial peptide splicing either with itself or with other demidefensins. However among cyclopeptides screened for antimicrobial activity, no peptides that would have been produced from this sequence were detected.
