Olivera, Baldomero M.; Bulaj, Grzegorz | Novel conantokins from Conus parius venom are specific antagonists of N-methyl-D-aspartate receptors | 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 γ-carboxyglutamate (Gla) residues, a post-translationally modified amino acid characteristic of conantokins.
