RA Craik D.J., Daly N.L., Bond T., Waine C.;
RT "Plant cyclotides: a unique family of cyclic and knotted proteins that
RT defines the cyclic cystine knot structural motif.";
RL J. Mol. Biol. 294:1327-1336(1999).
CC -!- FUNCTION: Probably participates in a plant defense mechanism.
CC -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC structurally defines this protein as a knottin.
CC -!- PTM: This is a cyclic peptide.
CC -!- SIMILARITY: Belongs to the cyclotide family. Moebius 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}.
