title: Microbial metabolism of quinoline and related compounds. V. Degradation of 1H-4-oxoquinoline by Pseudomonas putida 33/1.
abstract: A bacterial strain was isolated with the ability to use 1H-4-oxoquinoline as the sole source of carbon, nitrogen and energy. On the basis of its physiological properties, this isolate was classified as Pseudomonas putida. 1H-3-Hydroxy-4-oxoquinoline, N-formylanthranilic acid, anthranilic acid and catechol were identified as intermediates in the degradation pathway. The latter was further degraded by ortho-cleavage. The enzymatic conversion of 1H-4-oxoquinoline into 1H-3-hydroxy-4-oxoquinoline requires oxygen and NADH. Experiments with 18O2 showed that the oxygen consumed in this enzymatic reaction is derived from the atmosphere.
