Nitrite elimination and hydrolytic ring cleavage in 2,4,6-trinitrophenol (picric acid) degradation.
Two hydrogenation reactions in the initial steps of degradation of 2,4,6-trinitrophenol produce the dihydride Meisenheimer complex of 2,4,6-trinitrophenol. The npdH gene (contained in the npd gene cluster of the 2,4,6-trinitrophenol-degrading strain Rhodococcus opacus HL PM-1) was shown here to encode a tautomerase, catalyzing a proton shift between the aci-nitro and the nitro forms of the dihy...
متن کاملEnzymes and Metabolites in Picric Acid (2,4,6-Trinitrophenol) and 2,4-Dinitrophenol Biodegradation
5 Abstract The bacterial strains Rhodococcus (opacus) erythropolis HL PM-1 and Nocardioides simplex FJ2-1A can use picric acid (TNP) and 2,4-dinitrophenol (DNP) as sole nitrogen source. Enzymes were identified which are isofunctional in both strains, using the same degradation mechanism. During the initial steps hydride ions were transferred to the aromatic ring of the electron deficient π-syst...
متن کاملOrphenadrinium picrate picric acid
The asymmetric unit of the title compound N,N-dimethyl-2-[(2-methyl-phen-yl)phenyl-meth-oxy]ethanaminium picrate picric acid, C(18)H(24)NO(+)·C(6)H(2)N(3)O(7) (-)·C(6)H(3)N(3)O(7), contains one orphenadrinium cation, one picrate anion and one picric acid mol-ecule. In the orphenadrine cation, the two aromatic rings form a dihedral angle of 70.30 (7)°. There is an intra-molecular O-H⋯O hydrogen ...
متن کاملRing cleavage and degradative pathway of cyanuric acid in bacteria.
The degradative pathway of cyanuric acid [1,3,5-triazine-2,4,6(1H,3H,5H)-trione] was examined in Pseudomonas sp. strain D. The bacterium grew with cyanuric acid, biuret, urea or NH4+ as sole source of nitrogen, and each substrate was entirely metabolized concomitantly with growth. Enzymes from strain D were separated by chromatography on DEAE-cellulose and three reactions were examined. Cyanuri...
متن کاملBacterial degradation of N-cyclopropylmelamine. The steps to ring cleavage.
The s-triazine cyclopropylmelamine (N-cyclopropyl-1,3,5-triazine-2,4,6-triamine) was degraded to about 6 mol of NH4+/mol of substrate by a mixture of two bacteria (strains A and D, both Pseudomonas spp.) Only strain A grew with cyclopropylmelamine as sole and limiting source of nitrogen. The organism obtained 2 mol of nitrogen/mol of substrate and excreted a product that was identified as cyclo...
