Carbazole 1,9a-dioxygenase (CARDO), a Rieske nonheme iron oxygenase (RO), is a three-component system composed of a terminal oxygenase (Oxy), ferredoxin, and a ferredoxin reductase. Oxy has angular dioxygenation activity against carbazole. Previously, site-directed mutagenesis of the Oxy-encoding gene from Janthinobacterium sp. strain J3 generated the I262V, F275W, Q282N, and Q282Y Oxy derivati...
We report the electrochemistry, spectroscopy, and electrogenerated chemiluminescence (ECL) of donor-acceptor compounds containing a quinoxaline derivative as the central core coupled with fluorene (CFPQ, CFPP, and MFPQ) and triphenylamine moieties (MAPQ). Cyclic voltammetry of all four derivatives show reversible reduction waves (assigned to the formation of the radical anion) localized in the ...
1. Enzymic esterifications of 2-(N-hydroxyacetamido)fluorene and several other hydroxamic acids by liver cytosol were studied. Determination of 2-acetamido-3-methylthiofluorene was used for the assay. 2. With rat liver cytosol, requirement for ATP, Mg(2+) and SO(4) (2-) suggested formation of phosphate and sulphate esters of 2-(N-hydroxyacetamido)fluorene. 3. Rats showed sex and age differences...
a carcinogen originally discovered by Wilson, DeEds, and Cox (28), has been shown by these and many other investigators to be a highly active carcinogen that attacks nu merous sites in the rat and mouse. In addition, the parent hydrocarbon, fluorene, and several of its other derivatives have been tested for carcinogenic activity in the rat. Fluorene and its oxidation product, fluorenone, are in...
A fluorene-degrading strain named USTB-C was isolated from crude oil of production well in Dagang oil field, southeast of Tianjin, northeast China. The 16S rDNA sequence of USTB-C showed 100% similarity with that of Rhodococcus erythropolis PR4, it was belonged to Rhodococcus. The strain USTB-C could remove 55.8% of fluorene with an initial concentration of 100 mg L in 23 days without other sub...
