About: Contryphan

An Entity of Type: protein, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The contryphans (conus + tryptophan) are a family of peptides that are active constituents of the potent venom produced by cone snail (genus Conus). The two amino acid cysteine residues in contryphans are linked by a disulfide bond. In addition, contryphans undergo an unusual degree of post-translational modification including epimerization of leucine and tryptophan, tryptophan bromination, amidation of the C-terminus, and proline hydroxylation. In the broader scheme of genetic conotoxin classification, contryphans are members of "Conotoxin Superfamily O2."

dbo:abstract
  • The contryphans (conus + tryptophan) are a family of peptides that are active constituents of the potent venom produced by cone snail (genus Conus). The two amino acid cysteine residues in contryphans are linked by a disulfide bond. In addition, contryphans undergo an unusual degree of post-translational modification including epimerization of leucine and tryptophan, tryptophan bromination, amidation of the C-terminus, and proline hydroxylation. In the broader scheme of genetic conotoxin classification, contryphans are members of "Conotoxin Superfamily O2." (en)
  • I contrifani sono una famiglia di peptidi che sono costituenti attivi del veleno prodotto da molluschi gasteropodi marini appartenenti al genere Conus. I due residui di amminoacidi cisteina presenti nei contrifani sono legati da un legame disolfuro. I contrifani subiscono un insolito grado di modificazioni post-traduzionali comprese l'epimerizzazione di triptofano e leucina, bromurazione del triptofano, ammidazione del C-terminale, e idrossilazione della prolina.
