Toxin fs2
WebThe three residues that differ between FS2 and calciseptine are shown in red. Calciseptine ( CaS ) is a natural neurotoxin isolated from the black mamba Dendroaspis p. polylepis venom . This toxin consists of 60 amino acids with four disulfide bonds . WebThe identification and structural determination of the criticalamino acid residues causing the calcium channel blocking effects of theangusticeps type III toxin FS2 is described. Alignments withmore than 200 different short and long neuro-, cyto-, muscarinic and otherangusticeps-type toxins yielded 12 amino acid residues at the tips of loopsII and III …

Therefore, it is likely that these toxins also will block L-type Ca2+ channels. To test the proposed binding site on calciseptine and FS2, an eight-residue peptide, named L-calchin (L-type calcium channel inhibitor), was synthesized and …
