Inability of muconate cycloisomerases to cause dehalogenation during conversion of 2-chloro-cis,cis-muconate.
The conversion of 2-chloro-cis,cis-muconate by muconate cycloisomerase from Pseudomonas putida PRS2000 yielded two products which by nuclear magnetic resonance spectroscopy were identified as 2-chloro- and 5-chloromuconolactone. High-pressure liquid chromatography analyses showed the same compounds to be formed also by muconate cycloisomerases from Acinetobacter calcoaceticus ADP1 and Pseudomon...
متن کاملMicroperoxidase/H2O2-mediated alkoxylating dehalogenation of halophenol derivatives in alcoholic media.
The results of this study report the H2O2-driven microperoxidase-8 (MP8)-catalyzed dehalogenation of halophenols such as 4-fluorophenol, 4-chlorophenol, 4-bromophenol, and 2-fluorophenol in alcoholic solvents. In methanol, the conversion of the para-halophenols and 2-fluorophenol to, respectively, 4-methoxyphenol and 2-methoxyphenol, as the major dehalogenated products is observed. In ethanol, ...
متن کاملContinuous-flow column study of reductive dehalogenation of PCE upon bioaugmentation with the Evanite enrichment culture.
A continuous-flow anaerobic column experiment was conducted to evaluate the reductive dechlorination of tetrachloroethene (PCE) in Hanford aquifer material after bioaugmentation with the Evanite (EV) culture. An influent PCE concentration of 0.09 mM was transformed to vinyl chloride (VC) and ethene (ETH) within a hydraulic residence time of 1.3 days. The experimental breakthrough curves were de...
متن کاملAction of Nitro- and Halophenols upon Oxygen Consumption and Phosphorylation by a Cell-free Particulate System from Arbacia Eggs
1. The ability of 4,6-dinitrocresol and eight other substituted phenols to stimulate oxygen uptake and inhibit phosphorylation by a cell-free particulate system from unfertilized Arbacia eggs has been determined. Five of those agents can produce both stimulation of oxygen consumption and inhibition of phosphorylation; one inhibits both oxygen consumption and phosphorylation; and two have no eff...
متن کاملStereospecificity of 2-monochloropropionate dehalogenation by the two dehalogenases of Pseudomonas putida PP3: evidence for two different dehalogenation mechanisms.
Pseudomonas putida PP3 grew on DL-2-monochloropropionate (2MCPA) with a release of chloride ions consistent with the dechlorination of both isomers. The organism grew on either D- or L-2MCPA. Dehalogenase activity in cell-free extracts showed that both D- and L-2MCPA were dehalogenated. Pseudomonas putida PP3 contains two dehalogenases, and studies with the separated enzymes revealed that the f...
