Reaction: anthranilate + FADH2 + O2 = 3-hydroxyanthranilate + FAD + H2O
Glossary: anthranilate = 2-aminobenzoate
Other name(s): anthranilate 3-hydroxylase; anthranilate hydroxylase
Systematic name: anthranilate,FADH2:oxygen oxidoreductase (3-hydroxylating)
Comments: 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.
