additional information | kinetics of IDO-catalyzed indole oxidation as supported by H2O2, overview. The rate of disappearance of indole as a function of [H2O2] in the IDOFe3+-catalyzed reaction exhibits Michaelis-Menten behavior, with Km of about 1.1 mM for peroxide [indole] | Homo sapiens |

1.13.11.52 | additional information | Homo sapiens | the enzyme catalyzes the oxidation of indole by H2O2, with generation of 2- and 3-oxoindole as the major products, in the absence of O2 and reducing agents and is not inhibited by superoxide dismutase or hydroxyl radical scavengers, although it is strongly inhibited by L-Trp. IDO inserts oxygen into indole in a reaction that is mechanistically analogous to the peroxide shunt pathway of cytochrome P450 | ? | - |
