CC   -!- FUNCTION: Probably participates in a plant defense mechanism.
CC       {ECO:0000250|UniProtKB:P56254, ECO:0000255|PROSITE-ProRule:PRU00395}.
CC   -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC       structurally defines this protein as a knottin. {ECO:0000305}.
CC   -!- PTM: Contains 3 disulfide bonds. {ECO:0000269|PubMed:21194241}.
CC   -!- PTM: This is a cyclic peptide. {ECO:0000255|PROSITE-ProRule:PRU00395,
CC       ECO:0000269|PubMed:21194241}.
CC   -!- MASS SPECTROMETRY: Mass=3154.99; Method=Electrospray;
CC       Evidence={ECO:0000269|PubMed:21194241};
CC   -!- SIMILARITY: Belongs to the cyclotide family. Bracelet subfamily.
CC       {ECO:0000255|PROSITE-ProRule:PRU00395}.
CC   -!- CAUTION: This peptide is cyclic. The start position was chosen by
CC       similarity to cyclotide cter-A for which the DNA sequence is known.
CC       {ECO:0000305}.
