RA   Burman R., Gruber C.W., Rizzardi K., Herrmann A., Craik D.J., Gupta M.P.,
RA   Goransson U.;
RT   "Cyclotide proteins and precursors from the genus Gloeospermum: filling a
RT   blank spot in the cyclotide map of Violaceae.";
RL   Phytochemistry 71:13-20(2010).
CC   -!- FUNCTION: Probably participates in a plant defense mechanism.
CC       {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: This is a cyclic peptide. {ECO:0000255|PROSITE-ProRule:PRU00395,
CC       ECO:0000269|PubMed:19879608}.
CC   -!- MASS SPECTROMETRY: Mass=3373; Method=Electrospray;
CC       Evidence={ECO:0000269|PubMed:19879608};
CC   -!- SIMILARITY: Belongs to the cyclotide family. Bracelet subfamily.
CC       {ECO:0000305|PubMed:19879608}.
CC   -!- CAUTION: This peptide is cyclic. The start position was chosen by
CC       similarity to Voc2 (cycloviolacin-O11) for which the DNA sequence is
CC       known. {ECO:0000305}.
