title: Location of disulfide bridges in cardiotoxin from the venom of Formosan cobra (NAJA NAJA ATRA).
abstract: The location of the four disulfide bridges in cardiotoxin from the venom of the Formosan cobra, Naja naja atra, was determined by isolating cystine-containing peptides from the enzymic and partial acid hydrolyzates of the intact toxin. The results indicate that the disulfide bridges are formed by half cystine residues 3--21, 14--38, 42--53, and 54--59. The amino acid sequence at the position 48--49 was revised to -Leu-Val- instead of Val-Leu- as reported previously.
