Abstract
Similarly-placed cysteine residues (and in-register disulphide bridges ) in CnII-11 (C. noxius), noxius-toxin, charybdotoxin and leiurotoxin I, and amino acid sequence homology among these scorpion venom toxins enable classification of these molecules under CnII-11 type tertiary s tructural category under scorpion-toxin type proteins. Similar structu ral motif is also found in bee venom toxin apamin and apamin-type pept ides. Neurotoxin P2 (Amm P2) should be classified under the I5A type t ertiary structure.
