Abstract

The in vivo conversion of radioactive tryptophan to anthranilic acid and 2,3-dihydroxybenzoic acid by submerged cultures of Claviceps paspali was shown by Groeger and his co-workers (1965). More recently, Subba Rao et al. (1967a) reported that washed mycelial felts of Aspergillus niger incorporate the radioactivity from DL-tryptophan-C14 (benzene ring-labeled) into anthranilic acid, 3-hydroxyanthranilic acid, 2,3-dihydroxybenzoic acid and catechol. However, the conversion of anthranilic acid to 2,3-dihydroxybenzoic acid by cell-free preparations has not been demonstrated. In the present paper we report the demonstration of a soluble anthranilic acid hydroxylase from Aspergillus niger which is different from the anthranilic acid hydroxylases reported so far from microbes and higher plants.
