IntEnz Enzyme Nomenclature


Accepted name:
anthranilate 3-monooxygenase (FAD)
Other names:
anthranilate 3-hydroxylase
anthranilate hydroxylase
Systematic name:
anthranilate,FAD:oxygen oxidoreductase (3-hydroxylating)



This enzyme, isolated from the bacterium Geobacillus thermodenitrificans, participates in the pathway of tryptophan degradation. The enzyme is part of a system that also includes a bifunctional riboflavin kinase/FMN adenylyltransferase and an FAD reductase, which ensures ample supply of FAD to the monooxygenase.
