CC   -!- FUNCTION: Probably participates in a plant defense mechanism
CC       (Probable). Not active against Gram-negative bacteria E.coli ATCC
CC       700926, K.pneumoniae ATTC 13883 and P.aeruginosa ATCC 39018 at
CC       concentration up to 100 uM (PubMed:21596752). Has cytotoxic but no
CC       hemolytic activity (PubMed:21596752). {ECO:0000255,
CC       ECO:0000255|PROSITE-ProRule:PRU00395, ECO:0000269|PubMed:21596752}.
CC   -!- TISSUE SPECIFICITY: Expressed in flower, stem, shoot and pod but not in
CC       root, leaf, seed and nodule (at protein level).
CC       {ECO:0000269|PubMed:21596752}.
CC   -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC       structurally defines this protein as a knottin. {ECO:0000305}.
CC   -!- PTM: This is a cyclic peptide. {ECO:0000255|PROSITE-ProRule:PRU00395,
CC       ECO:0000269|PubMed:21596752}.
CC   -!- MASS SPECTROMETRY: Mass=3259; Method=MALDI;
CC       Evidence={ECO:0000269|PubMed:21596752};
CC   -!- SIMILARITY: Belongs to the cyclotide family. Moebius subfamily.
CC       {ECO:0000303|PubMed:21596752}.
