 Cysteamine dioxygenase

In enzymology, a cysteamine dioxygenase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are 2-aminoethanethiol and O2, whereas its product is hypotaurine.This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases).
