ID 1.13.11.91 DE 3-mercaptopropionate dioxygenase. AN 3-mercaptopropionic acid dioxygenase. AN 3-sulfanylpropanoate dioxygenase. CA 3-sulfanylpropanoate + O2 = 3-sulfinopropanoate + H(+). CC -!- This bacterial enzyme contains an iron(2+) atom coordinated by three CC protein-derived histidines and a Ser-His-Tyr motif. CC -!- It is similar to EC 1.13.11.20 and can act on L-cysteine, but has a CC much higher activity with its native substrate, 3-sulfanylpropanoate. DR Q9I0N5, 3MDO_PSEAE ; //
