ENZYME entry: EC 1.13.11.19

Accepted Name
Cysteamine dioxygenase.
Alternative Name(s)
Cysteamine oxygenase.
Persulfurase.
Reaction catalysed
2-aminoethanethiol + O(2) <=> hypotaurine
Cofactor(s)
Fe cation.
Comment(s)
  • Involved in the biosynthesis of taurine.
  • Requires catalytic amounts of a cofactor-like compound, such as sulfur, sufide, selenium or methylene blue for maximal activity.
  • 3-aminopropanethiol (homocysteamine) and 2-mercaptoethanol can also act as substrates, but glutathione, cysteine, and cysteine ethyl- and methyl esters are not good substrates.
