<p>Anthranilate (2-aminobenzoate) is an intermediate of tryptophan (Trp) biosynthesis and degradation. Members of this family are the small subunit of anthranilate 1,2-dioxygenase, which acts in Trp degradation by converting anthranilate to catechol. Closely related paralogs typically are the benzoate 1,2-dioxygenase small subunit, among the larger set of ring-hydroxylating dioxygenases.</p> Anthranilate 1,2-dioxygenase, small subunit
