ID 1.13.11.19 DE cysteamine dioxygenase. AN cysteamine oxygenase. AN persulfurase. CA cysteamine + O2 = H(+) + hypotaurine. CC -!- Involved in the biosynthesis of taurine. CC -!- 3-Aminopropanethiol (homocysteamine) and 2-sulfanylethan-1-ol CC (2-mercaptoethanol) can also act as substrates, but glutathione, CC cysteine, and cysteine ethyl- and methyl esters are not good CC substrates.
