WebCystine [ edit] Cystine is a dimer consisting of two cysteine molecules and the formation of a disulfide bond. This amino acid is a rate limiting substrate used in the SLC7A11 cystine/glutamate transporter and is usually imported into the cell. Cysteine-158 is specifically used in the formation of the disulfide bridge for the protein structure ...
