"We report the discovery and characterization of three conantokin peptides from the venom of Conus parius. Each peptide (conantokin-Pr1, -Pr2, and -Pr3) contains 19 amino acids with three gamma-carboxyglutamate (Gla) residues, a post-translationally modified amino acid characteristic of conantokins," scientists writing in the Journal of Biological Chemistry report.

"The new peptides contain several amino acid residues that differ from previous conantokin consensus sequences. Notably, the new conantokins lack Gla at the 3rd position from the N terminus, where the Gla residue is replaced by either aspartate or by another post-translationally modified residue,...
