Contryphan
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. ==Family members==
Contryphan family members include: where the sequence abbreviations stand for: * O = 4-trans-hydroxyproline, * l = D-leucine, L = L-leucine, * w = D-tryptophan, W = L-tryptophan, * γ = gamma-carboxyglutamic acid, * NH2 = C-terminal amidation and the remainder of the letters refer to the standard one letter abbreviations for amino acids.
