| Addtional Information | FUNCTION:Probably participates in a plant defense mechanism.DOMAIN:The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin.PTM:Cycloviolacin-O8 is a cyclic peptide.MASS SPECTROMETRY:Mass=3225.5; Method=MALDI; Range=85-115; Source=PubMed:16872274;SIMILARITY:Belongs to the cyclotide family. Bracelet subfamily.CAUTION:This peptide is cyclic. The start position was chosen by similarity to OAK1 (kalata-B1) for which the DNA sequence is known. |
