indoleamine 2,3-dioxygenase
Cat No.
EXWM-0571
Description
A protohemoprotein. Requires ascorbic acid and methylene blue for activity. This enzyme has broader substrate specificity than EC 1.13.11.11, tryptophan 2,3-dioxygenase. It is induced in response to pathological conditions and host-defense mechanisms and its distribution in mammals is not confined to the liver. While the enzyme is more active with D-tryptophan than L-tryptophan, its only known function to date is in the metabolism of L-tryptophan. Superoxide radicals can replace O2 as oxygen donor.
