Probably participates in a plant defense mechanism (Probable). Not active against Gram-negative bacteria E.coli ATCC 700926, K.pneumoniae ATTC 13883 and P.aeruginosa ATCC 39018 at concentration up to 100 uM (PubMed:21596752). Has cytotoxic but no hemolytic activity (PubMed:21596752). Expressed in flower, stem, shoot and pod but not in root, leaf, seed and nodule (at protein level). The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin. This is a cyclic peptide. Belongs to the cyclotide family. Moebius subfamily.
