TITLE HAIRPINLESS MUTANT OF OMEGA-ATRACOTOXIN-HV1A
COMPND MOL_ID: 1; COMPND 2 MOLECULE: OMEGA-ATRACOTOXIN-HV1A; COMPND 3 CHAIN: A; COMPND 4 SYNONYM: OMEGA-ACTX-HV1A; COMPND 5 ENGINEERED: YES
SOURCE MOL_ID: 1; SOURCE 2 SYNTHETIC: YES; SOURCE 3 OTHER_DETAILS: THIS PEPTIDE WAS CHEMICALLY SYNTHESIZED. SOURCE 4 THE NATIVE PEPTIDE IS NATURALLY FOUND IN HADRONYCHE SOURCE 5 VERSUTA (BLUE MOUNTAIN FUNNEL-WEB SPIDER).THE MUTANT SOURCE 6 HAIRPINLESS TOXIN WAS SYNTHESIZED BY SOLID-PHASE PEPTIDE SOURCE 7 SYNTHESIS, OXIDIZED/FOLDED IN A GLUTATHIONE REDOX BUFFER, SOURCE 8 THEN PURIFIED USING REVERSE-PHASE HPLC.
