Fig. 8From: Tryptophan catabolism in Pseudomonas aeruginosa and potential for inter-kingdom relationshipOverview of the proposed enzymatic pathways for tryptophan catabolism in Pa. Summary of the proven (dark arrows) and hypothetical (grey arrows) enzymatic reactions composing the kynurenine pathway of Pa. Hypothetical enzymes are highlighted in red. TDO: tryptophan-2,3-dioxygenase, KYNF: kynurenine formamidase, KYNU: kynureninase, KAT: kynurenine aminotransferase, KMO: kynurenine monooxygenaseBack to article page
