Toxin C(13)S(2)C(3)

Toxin C(13)S(2)C(3) is a cysteine-rich toxin peptide variant where selective Cys-to-Ser replacements shift disulfide topology. Such substitutions alter folding pathways, stability, and channel-recognition profiles. Researchers analyze its three-dimensional structure and bioactivity relative to native toxin. Applications include disulfide engineering, ion-channel mapping, and toxin-structure studies.
