| Addtional Information | FUNCTION:Probably participates in a plant defense mechanism. Has low hemolytic activity.DOMAIN:The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin.PTM:Violacin-A is not a cyclic peptide.MASS SPECTROMETRY:Mass=3004.9; Method=MALDI; Range=80-106; Source=PubMed:16488428;MASS SPECTROMETRY:Mass=3004.3; Method=MALDI; Range=80-106; Source=PubMed:16872274;MISCELLANEOUS:The presence of a premature stop codon inhibits the translation of a key Asn residue that is thought to be required for cyclization.SIMILARITY:Belongs to the cyclotide family. Moebius subfamily. |
