Figure 1 Mechanism of lysosomal cystine depletion by cysteamine. Cysteamine enters the lysosome through an unknown transporter and breaks the disulfide bond in cystine. This results in formation of cysteine and a new cysteine-cysteamine mixed disulfide, each of which can exit the lysosome through its own transporter.
