Description |
Cyclotides (cyclo peptides) are plant peptides of ~30 amino acids with a head to-tail cyclic backbone and six cysteine residues involved in three disulphide bonds. The cyclotides are extremely resistant to proteolysis and are remarkably stable. Cyclotides display a diverse range of biological activities, including uterotonic activity, inhibition of neurotensin binding, hemolytic, anti-HIV and anti-microbial activity. This range of biological activities makes cyclotides amenable to potential pharmaceutical and agricultural applications. Although their precise role in plants has not yet been reported, it appears that they are most likely present as defence molecules [PMID: 10600388, PMID: 12482862, PMID: 12482868, PMID: 12946412]. |

Note:
The format for Signature ID is the family name, followed by H or P for HMM or Pattern respectively. The integer suffixed to H or P denotes the length of the sequences used to create the family signature. If no integer is suffixed, it indicates that the signature was created using all the sequences of the family. The integer following the underscore denotes the number of sequences used for the creation of signatures.
For example:
AureinH_21 is a HMM for Aurein family created using 21 sequences.
AureinP16_9 is a pattern for Aurein family derived using 9 input sequences that are 16 residues long. |
