Questiоns 4–9 refer tо this tоxic peptide. Generаl Instructions: If the question does not require you to drаw а structure, you may answer using either the full name of an amino acid or its three-letter or single-letter code. Many animal toxins are peptides. One of these is a 42-residue toxic peptide found in the South American rattlesnake, Crotalus durissus terrificus. The primary sequence of this peptide is shown below, and its structure is shown in the figure. YKQCHKKGGHCFPKEKICLPPSSDFGKMDCRWRWKCCKKGSG Image Description and Attribution A 3D protein structure showing the positions of cysteine residues (Cys4, Cys11, Cys18, Cys30, Cys36, and Cys37) highlighted in yellow. The protein has an N-terminal (N) and a C-terminal (C) with distinct secondary structures: alpha-helices in red and beta-sheets in blue, connected by green loops. The cysteine residues form disulfide bonds, contributing to the protein’s stability and shape. Yikrazuul, Structure of Crotamin, Wikimedia Commons, (CC BY-SA 3.0).
