ID 1.13.11.19 DE Cysteamine dioxygenase. AN Cysteamine oxygenase. AN Persulfurase. CA 2-aminoethanethiol + O(2) = hypotaurine. CF Iron. CC -!- Involved in the biosynthesis of taurine. CC -!- Requires catalytic amounts of a cofactor-like compound, such as CC sulfur, sufide, selenium or methylene blue for maximal activity. CC -!- 3-aminopropanethiol (homocysteamine) and 2-mercaptoethanol can also CC act as substrates, but glutathione, cysteine, and cysteine ethyl- and CC methyl esters are not good substrates.
