Genome analysis of Desulfotomaculum kuznetsovii reveals a physiological similarity with Pelotomaculum thermopropionicum

Desulfotomaculum kuznetsovii is a moderately thermophilic member of the polyphyletic spore-forming genus Desulfotomaculum in the family Peptococcaceae. This species is of interest because it originates from deep subsurface thermal mineral water at a depth ...

Comparative study of three lactate oxidases from Aerococcus viridans for biosensing applications

Giovanni De Micheli, Sandro Carrara, Irene Taurino

A comparison between engineered and commercially available L-lactate oxidases from Aerococcus viridans was conducted for biosensing applications. Enzymes were adsorbed onto the surfaces of graphite electrodes modified with multi-walled carbon nanotubes. Th ...

The NAD+ Precursor Nicotinamide Riboside Enhances Oxidative Metabolism and Protects against High-Fat Diet-Induced Obesity

Johan Auwerx, Kristina Schoonjans, Carlos Canto Alvarez, Pénélope Andreux, Karl Gademann, Richardus Houtkooper, Eija Riitta Pirinen, Hiroyasu Yamamoto, Maaike Hélène Oosterveer, Pablo Jose Fernandez Marcos

As NAD(+) is a rate-limiting cosubstrate for the sirtuin enzymes, its modulation is emerging as a valuable tool to regulate sirtuin function and, consequently, oxidative metabolism. In line with this premise, decreased activity of PARP-1 or CD38-both NAD(+ ...

In Vivo Evidence for Lactate as a Neuronal Energy Source

Pierre Magistretti, Renaud Jolivet

Cerebral energy metabolism is a highly compartmentalized and complex process in which transcellular trafficking of metabolites plays a pivotal role. Over the past decade, a role for lactate in fueling the energetic requirements of neurons has emerged. Furt ...

Reversible acetylation of PGC-1: connecting energy sensors and effectors to guarantee metabolic flexibility

Johan Auwerx, Kristina Schoonjans, Ellen Helena Jeninga

rganisms adapt their metabolism to meet ever changing environmental conditions. This metabolic adaptation involves at a cellular level the fine tuning of mitochondrial function, which is mainly under the control of the transcriptional co-activator prolifer ...

A comprehensive model of purine uptake by the malaria parasite Plasmodium falciparum: identification of four purine transport activities in intraerythrocytic parasites

Plasmodium falciparum is incapable of de novo purine biosynthesis, and is absolutely dependent on transporters to salvage purines from the environment. Only one low-affinity adenosine transporter has been characterized to date. In the present study we repo ...

Thermodynamics-Based Metabolic Flux Analysis

Vassily Hatzimanikatis

ABSTRACT A new form of metabolic flux analysis (MFA) called thermodynamics-based metabolic flux analysis (TMFA) is introduced with the capability of generating thermodynamically feasible flux and metabolite activity profiles on a genome scale. TMFA involve ...

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 ...

Metabolic compartmentalization in the human cortex and hippocampus: evidence for a cell- and region-specific localization of lactate dehydrogenase 5 and pyruvate dehydrogenase

Pierre Magistretti, Luc Pellerin

BACKGROUND: For a long time now, glucose has been thought to be the main, if not the sole substrate for brain energy metabolism. Recent data nevertheless suggest that other molecules, such as monocarboxylates (lactate and pyruvate mainly) could be suitable ...
