OX   NCBI_TaxID=341256;
RN   [1] {ECO:0000305}
RP   PROTEIN SEQUENCE.
RX   PubMed=12782038; DOI=10.1016/s0003-2697(03)00114-3;
RA   Goransson U., Broussalis A.M., Claeson P.;
RT   "Expression of Viola cyclotides by liquid chromatography-mass spectrometry
RT   and tandem mass spectrometry sequencing of intercysteine loops after
RT   introduction of charges and cleavage sites by aminoethylation.";
RL   Anal. Biochem. 318:107-117(2003).
CC   -!- FUNCTION: Probably participates in a plant defense mechanism.
CC       {ECO:0000305}.
CC   -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC       structurally defines this protein as a knottin.
CC       {ECO:0000250|UniProtKB:P56879}.
CC   -!- PTM: This is a cyclic peptide. {ECO:0000255|PROSITE-ProRule:PRU00395,
CC       ECO:0000269|PubMed:12782038}.
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 OAK1 (kalata-B1) for which the DNA sequence is known.
CC       {ECO:0000305}.
