The inducible trimethylamine-N-oxide reductase which migrates on non-denaturing polyacrylamide gels with an RF of 0.22, has been purified from the soluble fraction of wild-type E. coli K12. The molecular weight of the purified enzyme estimated by molecular-sieve chromatography is about 230 000. It is composed of two subunits of molecular weight 110 000. Antiserum specific for the enzyme has been produced. Gel filtration on Sephadex G-200 of the soluble fraction gave two peaks of trimethylamine-N- ...

The redox properties of the iron-sulfur centers of the two nitrate reductases from Escherichia coli have been investigated by EPR spectroscopy. A detailed study of nitrate reductase A performed in the range +200 mV to -500 mV shows that the four iron-sulfur centers of the enzyme belong to two classes with markedly different redox potentials. The high-potential group comprises a [3Fe-4S] and a [4Fe-4S] cluster whose midpoint potentials are +60 mV and +80 mV, respectively. Although these centers are magnetically ...

The final stages of bacterial molybdenum cofactor (Moco) biosynthesis correspond to molybdenum chelation and nucleotide attachment onto an unique and ubiquitous structure, the molybdopterin. Using a bacterial two-hybrid approach, here we report on the in vivo interactions between MogA, MoeA, MobA, and MobB implicated in several distinct although linked steps in Escherichia coli. Numerous interactions among these proteins have been identified. Somewhat surprisingly, MobB, a GTPase with a yet unclear ...

The periplasmic trimethylamine N-oxide (TMAO) reductase from the marine bacteria Shewanella massilia is involved in a respiratory chain, having trimethylamine N-oxide as terminal electron acceptor. This molybdoenzyme belongs to the dimethyl sulfoxide (DMSO) reductase family, but has a different substrate specificity than its homologous enzyme. While the DMSO reductases reduce a broad spectra of organic S-oxide and N-oxide compounds, TMAO reductase from Shewanella massilia reduces only TMAO as the ...

Nitrate reductase (nitrite:(acceptor) oxidoreductase, EC 1.7.99.4) and trimethylamine N-oxide reductase (NADH:trimethylamine-N-oxide oxidoreductase, EC 16.6.9) activities were reconstituted by incubation of the association factor FA (the putative product of the chlB gene) with the soluble extract of the chlB mutant grown anaerobically in the presence of trimethylamine N-oxide. When soluble extracts of the chlB mutant grown on 10 mM sodium tungstate, a molybdenum competitor, were used in complementation ...

Reduction of trimethylamine N-oxide (TMAO) in Escherichia coli involves the terminal molybdoreductase TorA, located in the periplasm, and the membrane anchored c type cytochrome TorC. In this study, the role of the TorD protein, encoded by the third gene of torCAD operon, is investigated. Construction of a mutant, in which the torD gene is interrupted, showed that the absence of TorD protein leads to a two times decrease of the final amount of TorA enzyme. However, specific activity and biochemical ...

We used an anti-trimethylamine-N-oxide reductase (EC 1.6.6.9) serum and different immunological techniques (Ouchterlony, rocket immunoelectrophoresis, immunoblotting) to show that dimethylsulphoxide (DMSO), tetrahydrothiophene 1-oxide (THTO) and pyridine N-oxide (PNO) were effective inducers of the inducible form of trimethylamine N-oxide reductase. We confirmed this genetically and biochemically using a strain in which phage MudII 1734 carrying lacZ was inserted into torA, the structural gene for inducible ...

Tellurite and selenate reductase activities were identified in extracts of Escherichia coli. These activities were detected on non-denaturing polyacrylamide gels using an in situ methyl viologen activity-staining technique. The activity bands produced from membrane-protein extracts had the same R F values as those of nitrate reductases (NRs) A and Z. Tellurite and selenate reductase activities were absent from membranes obtained from mutants deleted in NRs A and Z. Further evidence of the tellurite ...

The chlorate resistance mutants are pleitropically defective in the activity of all molybdoenzymes in Escherichia coli. Protein FA addition to the soluble fraction of a chlB mutant, brings about the activation of the molybdoenzyme, respiratory nitrate reductase, an inactive precursor of which is present in the chlB fraction. The rate of the activation process but not its extent is dependent upon the quantity of protein FA present. Protein FA activity is constitutively expressed and was present in ...

La question du lien entre traumatisme et addiction est soulevée depuis les travaux de Ferenczi et fait aujourd’hui l’objet de multiples recherches psychopathologiques, épidémiologiques ou encore neurobiologiques. Dans une perspective psychodynamique et à l’aide de modèles issus de la psychosomatique, nous avons cherché à comprendre en quoi le recours à un objet d’addiction répond, pour le sujet traumatisé, d’un double mouvement. D’un côté, il vise à réduire la détresse psychique, en réprimant et ...

Understanding when and how metal cofactor insertion occurs into a multisubunit metalloenzyme is of fundamental importance. Molybdenum cofactor insertion is a tightly controlled process that involves specific interactions between the proteins that promote cofactor delivery, enzyme-specific chaperones, and the apoenzyme. In the assembly pathway of the multisubunit molybdoenzyme, membrane-bound nitrate reductase A from Escherichia coli, a NarJ-assisted molybdenum cofactor (Moco) insertion step, must ...

The few well-characterized fungal growth-regulating substances include 10-oxo-trans-8-decenoic acid (ODA) and hercynine. This report deals with production and tissue location of ODA. It also describes some biological activities of addition of ODA, hercynine, and cytokinins on growth and postharvest morphogenesis of Agaricus bisporus. Production of ODA in sporophore extracts was limited mainly by oxygen availability and the possible occurrence of a competitive metabolic pathway. Presumably synthesized ...

Using a wide variety of N- and S-oxide compounds we have shown by kinetic analysis that only two N-oxidestrimethylamine-N-oxide and 4-methylmorpholine-N-oxide, can be considered good substrates for trimethylamine-N-oxide (TMAO) reductase on the basis of their kcatKm ratio. This result demonstrates that TMAO reductase possesses a high substrate specificity. Induction of the torCAD operon using the same S- and N-oxide compounds was also analyzed. We demonstrate that there is no correlation between ...

Anionic lipids play a variety of key roles in membrane function, including functional and structural effects on respiratory complexes. However, little is known about the molecular basis of these lipid–protein interactions. In this study, NarGHI, an anaerobic respiratory complex of Escherichia coli , has been used to investigate the relations in between membrane-bound proteins with phospholipids. Activity of the NarGHI complex is enhanced by anionic phospholipids both in vivo and in vitro. The anionic ...

Several compounds, mainly opioid agonists such as methadone, are currently used for long term medication of heroin addicts. Nevertheless, these maintenance treatments have the disadvantage to induce a dependence to another opiate. As interactions between opioid and cannabinoid systems have been demonstrated, the ability of the CB(1) antagonist, SR141716A to reduce morphine-induced addiction was investigated. The effects of SR141716A on the rewarding responses of morphine were evaluated in the place ...

A biochemical and immunological study has revealed a new formate dehydrogenase isoenzyme in Escherichia coli. The enzyme is an isoenzyme of the respiratory formate dehydrogenase (FDH-N) which forms part of the formate to nitrate respiratory pathway found in the organisms when it is grown anaerobically in the presence of nitrate. The new enzyme, termed FDH-Z, cross reacts with antibodies raised to FDH-N and possesses a similar polypeptide composition to FDH-N, FDH-Z catalyses the phenazine methosulphate- ...

Abstract Abstract In order to predict the geometry and electronic spectra of spiropyrans and spirooxazines, the validity of some semi-empirical methods has been checked. Results show that both AM1 and GenMol give reasonable geometrical values. If CNDO/S and INDO/S calculate well theoretical absorption of closed forms, in contrast, the Δmax obtained for opened forms are underevaluated.
