Spectroscopic Investigation of Cysteamine Dioxygenase

Biochemistry, 2020
Thiol dioxygenases are mononuclear non-heme FeII-dependent metalloenzymes that initiate the oxidative catabolism of thiol-containing substrates to their respective sulfinates. Cysteine dioxygenase (CDO), the best characterized mammalian thiol dioxygenase, contains a three-histidine (3-His) coordination environment rather than the 2-His-1-carboxylate ...

Evaluation of NACA and diNACA in human cystinosis fibroblast cell cultures as potential treatments for cystinosis

Orphanet Journal of Rare Diseases, 2022
Background Cystinosis is a rare autosomal recessive lysosomal storage disease, associated with high morbidity and mortality. Mutations in the CTNS gene disable a membrane protein responsible for the transport of cystine out of the lysosome.
