Abstract:Summary Acinetobacter calcoaceticus dissimilates tryptophan via the beta-ketoadipate pathway. The first enzyme, tryptophan oxygenase (l-tryptophan: oxygen oxidoreductase; EC 1.13.1.12), is substrate-induced by tryptophan. The second two enzymes, formamidase (aryl-formylamine amidohydrolase; EC 3.5.1.9) and kynureninase (l-kynurenine hydrolase; EC 3.7.1.3), are induced by the next intermediate, kynurenine. The last enzyme specific to tryptophan dissimilation, anthranilate oxidase, is substrate induced. This inductive pattern is in marked contrast to the extensive coordinacy of enzyme synthesis characteristic of the remainder of the beta-ketoadipate pathway.
