Abstract
α-Bungarotoxin (α-BuTx) was isolated from the venom of the Formosan banded krait (Bungarus multicinctus). The amino acid sequence was determined by a combination of conventional methods. In contrast to the sequence of α-BuTx reported by Mebs et al. [(1971) Biochem. Biophys. Res. Commun. 44, 711–716], our results revealed the presence of -Pro- , - and - at positions 9–11, 67–68 and 71–72 from the amino-terminal, respectively, and not -Pro- , - and - as reported previously.
