REL
REL
This peptide was chemically synthesized. The native peptide is naturally found in Hadronyche versuta (Blue mountain funnel-web spider).The mutant hairpinless toxin was synthesized by solid-phase peptide synthesis, oxidized/folded in a glutathione redox buffer, then purified using reverse-phase HPLC.
sample
This structure was determined using standard 2D homonuclear techniques.
