title: Crystal structure of bucain, a three-fingered toxin from the venom of the Malayan krait (Bungarus candidus).
abstract: Bucain, a potent neurotoxin isolated from the venom of the Malayan krait (Bungarus candidus), induces paralysis and death. Its crystal structure has been determined at 2.10 A resolution and based on the molecular topology and hydrophobicity profile is structurally classified as a three-fingered alpha-neurotoxin possessing a positively charged AChR-binding site.
