Purification and characterization of a neurotoxic peptide huwentoxin-III and a natural inactive mutant from the venom of the spider Selenocosmia huwena Wang (Ornithoctonus huwena Wang).

Abstract excerpt

A novel neurotoxic peptide, named huwentoxin-III, and a natural mutant have been isolated from the venom of the spider Selenocosmia huwena Wang (Ornithoctonus huwena Wang). The average molecular weights of the two peptides were determined as 3853.35 and 3667.40 by mass spectrometry, respectively....
