THE TWIN-ARGININE TRANSLOCATION PATHWAY IN THE OBLIGATE ANAEROBE DESULFITOBACTERIUM

Christof Holliger, Julien Maillard, Emmanuelle Rohrbach, Aurélie Duret

The genus Desulfitobacterium belong to the low-GC gram-positive phylogenic group and is a versatile obligate anaerobe capable of reducing very diverse terminal electron acceptors such as sulfite, nitrate, fumarate, thiosulfate, and a few polluting chlorina ...

The curse of taxonomic uncertainty in biogeographical studies of free-living terrestrial protists: a case study of testate amoebae from Amsterdam Island

Edward Mitchell, Thierry Jean Heger

Aim A current debate in microbial biogeography contrasts two views concerning the distribution of free-living microorganisms. The first view assumes a ubiquitous distribution, while the second view assumes that at least some species have limited geographic ...

Adaptation of Aerobically Growing Pseudomonas aeruginosa to Copper Starvation

Restricted bioavailability of copper in certain environments can interfere with cellular respiration because copper is an essential cofactor of most terminal oxidases. The global response of the metabolically versatilebacterium and opportunistic pathogen P ...

Activity-dependent regulation of energy metabolism by astrocytes: an update

Pierre Magistretti, Luc Pellerin

Astrocytes play a critical role in the regulation of brain metabolic responses to activity. One detailed mechanism proposed to describe the role of astrocytes in some of these responses has come to be known as the astrocyte-neuron lactate shuttle hypothesi ...

Genome-scale thermodynamic analysis of Escherichia coli metabolism

Vassily Hatzimanikatis

Genome-scale metabolic models are an invaluable tool for analyzing metabolic systems as they provide a more complete picture of the processes of metab. The authors have constructed a genome-scale metabolic model of Escherichia coli based on the iJR904 mode ...

Hydrogenases of the dehalorespiring bacterium Desulfitobacterium hafniense strain TCE1

Benoît Zen-Ruffinen

Groundwater contamination by organochloric compounds became a major concern for public health during the last century. Chloroethenes, commonly used since the 1920's as degreasing and cleaning agents and as intermediates in chemical synthesis, accumulated i ...

Trans-inhibition of glutamate transport prevents excitatory amino acid-induced glycolysis in astrocytes

Pierre Magistretti, Luc Pellerin

Previous studies have demonstrated that activation of glutamate transporters promotes glycolysis in astrocytes. Current evidence indicates that compounds such as threo-beta-hydroxyaspartate (THA) are both competitive inhibitors and substrates for glutamate ...

Cellular mechanisms of brain energy metabolism and their relevance to functional brain imaging

Pierre Magistretti, Luc Pellerin

Despite striking advances in functional brain imaging, the cellular and molecular mechanisms that underlie the signals detected by these techniques are still largely unknown. The basic physiological principle of functional imaging is represented by the tig ...

Excitatory amino acids stimulate aerobic glycolysis in astrocytes via an activation of the Na+/K+ ATPase

Pierre Magistretti, Luc Pellerin

Astrocytes appear to be ideally localized to couple neuronal activity to energy metabolism. First, specialized processes, the astrocytic end-feet surround blood vessels, the source of glucose for the brain. Second, other processes ensheath synapses and exp ...

Cellular mechanisms of brain energy metabolism: relevance to functional brain imaging and to neurodegenerative disorders

Pierre Magistretti, Luc Pellerin

Astrocyte end-feet surround intraparenchymal microvessels and represent therefore the first cellular barrier for glucose entering the brain. As such, they are a likely site of prevalent glucose uptake. Astrocytic processes are also wrapped around synaptic ...
