Peptide tоxins in the venоms оf fish-hunting cone snаils (genus Conus) block synаptic trаnsmission by inhibition of the nicotinic acetylcholine receptor (α-conotoxins), presynaptic voltage-sensitive calcium channels (ω-conotoxins), and muscle sodium channel potentials (μ-conotoxins). The sequence of α-conotoxin SI is ECCNPACGRHYSC with an amidated C-terminal. Researchers were able to use [Pt(en)2Cl2]2+, a complex of platinum with ethylenodiamine (en), to generate three regioisomers (isomers that differ in the intramolecular disulfide bond location). The isomers are:  [C2-C13][C3-C7]ECCNPACGRHYSC-NH2 [C2-C3][C7-C13]ECCNPACGRHYSC-NH2 [C2-C7][C3-C13]ECCNPACGRHYSC-NH2 [C2-C3]ECCNPACGRHYSC-NH2 [C3-C13]ECCNPACGRHYSC-NH2 Which of the regioisomers are going to produce two peptides following treatment with chymotrypsin?
