Reaction: anthranilate + NADPH + H+ + O2 = 2,3-dihydroxybenzoate + NADP+ + NH3
Other name(s): anthranilate hydroxylase; anthranilate 2,3-dioxygenase (deaminating); anthranilate hydroxylase (deaminating); anthranilic hydroxylase; anthranilate 2,3-hydroxylase (deaminating)
Systematic name: anthranilate,NADPH:oxygen oxidoreductase (3-hydroxylating, deaminating)
Comments: The enzyme from Aspergillus niger is an iron protein; that from the yeast Trichosporon cutaneum is a flavoprotein (FAD). Previously EC 22.214.171.124.
