Abstract
Rickettsia prowazekii is an obligate intracytosolic pathogen and the causative agent of epidemic typhus fever in humans. As an evolutionary model of intracellular pathogenesis, rickettsiae are notorious for their use of transport systems that parasitize eukaryotic host cell biochemical pathways. Rickettsial transport systems for substrates found only in eukaryotic cell cytoplasm are uncommon among free-living microorganisms and often possess distinctive mechanisms. We previously reported that R. prowazekii acquires triose phosphates for phospholipid biosynthesis via the coordinated activities of a novel dihydroxyacetone phosphate transport system and an sn-glycerol-3-phosphate dehydrogenase (K. M. Frohlich et al., J. Bacteriol. 192:4281-4288, 2010). In the present study, we have determined that R. prowazekii utilizes a second, independent triose phosphate acquisition pathway whereby sn-glycerol-3-phosphate is directly transported and incorporated into phospholipids. Herein we describe the sn-glycerol-3-phosphate and dihydroxyacetone phosphate transport systems in isolated R. prowazekii with respect to kinetics, energy coupling, transport mechanisms, and substrate specificity. These data suggest the existence of multiple rickettsial triose phosphate transport systems. Furthermore, the R. prowazekii dihydroxyacetone phosphate transport systems displayed unexpected mechanistic properties compared to well-characterized triose phosphate transport systems from plant plastids. Questions regarding possible roles for dual-substrate acquisition pathways as metabolic virulence factors in the context of a pathogen undergoing reductive evolution are discussed.

Abstract
Rickettsia prowazekii is an obligate intracellular pathogen that possesses a small genome and a highly refined repertoire of biochemical pathways compared to those of free-living bacteria. Here we describe a novel biochemical pathway that relies on rickettsial transport of host cytosolic dihydroxyacetone phosphate (DHAP) and its subsequent conversion to sn-glycerol-3-phosphate (G3P) for synthesis of phospholipids. This rickettsial pathway compensates for the evolutionary loss of rickettsial glycolysis/gluconeogenesis, the typical endogenous source of G3P. One of the components of this pathway is R. prowazekii open reading frame RP442, which is annotated GpsA, a G3P dehydrogenase (G3PDH). Purified recombinant rickettsial GpsA was shown to specifically catalyze the conversion of DHAP to G3P in vitro. The products of the GpsA assay were monitored spectrophotometrically, and the identity of the reaction product was verified by paper chromatography. In addition, heterologous expression of the R. prowazekii gpsA gene functioned to complement an Escherichia coli gpsA mutant. Furthermore, gpsA mRNA was detected in R. prowazekii purified from hen egg yolk sacs, and G3PDH activity was assayable in R. prowazekii lysed-cell extracts. Together, these data strongly suggested that R. prowazekii encodes and synthesizes a functional GpsA enzyme, yet R. prowazekii is unable to synthesize DHAP as a substrate for the GpsA enzymatic reaction. On the basis of the fact that intracellular organisms often avail themselves of resources in the host cell cytosol via the activity of novel carrier-mediated transport systems, we reasoned that R. prowazekii transports DHAP to supply substrate for GpsA. In support of this hypothesis, we show that purified R. prowazekii transported and incorporated DHAP into phospholipids, thus implicating a role for GpsA in vivo as part of a novel rickettsial G3P acquisition pathway for phospholipid biosynthesis.

Abstract
A novel method exploiting the differential affinity of ADP and ATP to Mg(2+) was developed to measure mitochondrial ADP-ATP exchange rate. The rate of ATP appearing in the medium after addition of ADP to energized mitochondria, is calculated from the measured rate of change in free extramitochondrial [Mg(2+)] reported by the membrane-impermeable 5K(+) salt of the Mg(2+)-sensitive fluorescent indicator, Magnesium Green, using standard binding equations. The assay is designed such that the adenine nucleotide translocase (ANT) is the sole mediator of changes in [Mg(2+)] in the extramitochondrial volume, as a result of ADP-ATP exchange. We also provide data on the dependence of ATP efflux rate within the 6.8-7.8 matrix pH range as a function of membrane potential. Finally, by comparing the ATP-ADP steady-state exchange rate to the amount of the ANT in rat brain synaptic, brain nonsynaptic, heart and liver mitochondria, we provide molecular turnover numbers for the known ANT isotypes.

Abstract
Different from some more specialised short reviews, here a general although not encyclopaedic survey of the function, metabolic role, structure and mechanism of the ADP/ATP transport in mitochondria is presented. The obvious need for an "old fashioned" review comes from the gateway role in metabolism of the ATP transfer to the cytosol from mitochondria. Amidst the labours, 40 or more years ago, of unravelling the role of mitochondrial compartments and of the two membranes, the sequence of steps of how ATP arrives in the cytosol became a major issue. When the dust settled, a picture emerged where ATP is exported across the inner membrane in a 1:1 exchange against ADP and where the selection of ATP versus ADP is controlled by the high membrane potential at the inner membrane, thus uplifting the free energy of ATP in the cytosol over the mitochondrial matrix. Thus the disparate energy and redox states of the two major compartments are bridged by two membrane potential responsive carriers to enable their symbiosis in the eukaryotic cell. The advance to the molecular level by studying the binding of nucleotides and inhibitors was facilitated by the high level of carrier (AAC) binding sites in the mitochondrial membrane. A striking flexibility of nucleotide binding uncovered the reorientation of carrier sites between outer and inner face, assisted by the side specific high affinity inhibitors. The evidence of a single carrier site versus separate sites for substrate and inhibitors was expounded. In an ideal setting principles of transport catalysis were elucidated. The isolation of intact AAC as a first for any transporter enabled the reconstitution of transport for unravelling, independently of mitochondrial complications, the factors controlling the ADP/ATP exchange. Electrical currents measured with the reconstituted AAC demonstrated electrogenic translocation and charge shift of reorienting carrier sites. Aberrant or vital para-functions of AAC in basal uncoupling and in the mitochondrial pore transition were demonstrated in mitochondria and by patch clamp with reconstituted AAC. The first amino acid sequence of AAC and of any eukaryotic carrier furnished a 6-transmembrane helix folding model, and was the basis for mapping the structure by access studies with various probes, and for demonstrating the strong conformation changes demanded by the reorientation mechanism. Mutations served to elucidate the function of residues, including the particular sensitivity of ATP versus ADP transport to deletion of critical positive charge in AAC. After resisting for decades, at last the atomic crystal structure of the stabilised CAT-AAC complex emerged supporting the predicted principle fold of the AAC but showing unexpected features relevant to mechanism. Being a snapshot of an extreme abortive "c-state" the actual mechanism still remains a conjecture.

Abstract
Apoptosis is a form of programmed cell death important in the development and tissue homeostasis of multicellular organisms. Mitochondria have, next to their function in respiration, an important role in the apoptotic-signaling pathway. Malfunctioning at any level of the cell is eventually translated in the release of apoptogenic factors from the mitochondrial intermembrane space resulting in the organized demise of the cell. Some of these factors, such as AIF and endonuclease G, appear to be highly conserved during evolution. Other factors, like cytochrome c, have gained their apoptogenic function later during evolution. In this review, we focus on the role of cytochrome c, AIF, endonuclease G, Smac/DIABLO, Omi/HtrA2, Acyl-CoA-binding protein, and polypyrimidine tract-binding protein in the initiation and modulation of cell death in different model organisms. These mitochondrial factors may contribute to both caspase-dependent and caspase-independent processes in apoptotic cell death.

Abstract
Atractyloside (ATR) is widely used as a specific inhibitor of mitochondrial adenine nucleotide translocase and it is also a potent nephrotoxin that selectively injures the proximal tubule in vivo. This regioselectivity has been attributed to the prominence of mitochondria in the proximal tubule cells, but there have been no investigations to confirm this. In order to better understand the molecular basis of ATR-induced renal injury, oxidative phosphorylation was studied in freshly isolated rat proximal tubular and glomeruli fragments, and in isolated rat renal cortical mitochondria. In isolated renal mitochondrial, ATR significantly inhibited state 3 respiration in a dose-dependent manner, with the maximum inhibition achieved at the highest ATR concentration. Low doses of ATR (53 microM) inhibited respiration by 50%, an effect which was reversed by 2.5 mumol ADP. 2,4-Dinitrophenol (5 mM), which stimulated respiration in control mitochondria, failed to do this in the presence of ATR. Basal oxygen consumption was significantly inhibited by ATR (> 50 microM) in proximal tubule previously incubated for 1 h at 37 degrees C. The concentration-dependent inhibition of oxygen uptake by the proximal tubule was maintained in the presence of 1 mM ouabain or 0.25 mg/ml nystatin. Glomeruli have active mitochondrial respiration (about half that of the proximal tubules), but were not affected by ATR at concentrations up to 500 microM. These data demonstrates that both purified renal mitochondria and freshly isolated fragments of the proximal tubule exposed to ATR in vitro exhibit similar alteration in respiratory parameters that demonstrate inhibition of state 3 mitochondrial respiration, but there was no significant effect on glomeruli cells. Thus, the inhibition of oxidative phosphorylation may be an early event in ATR-induced nephrotoxicity, where the prominence of mitochondria in the proximal tubule explain, in part, the localised injury. The resistance of the glomeruli suggest that preferential transport of ATR may also contribute to the sensitivity of the proximal tubule.

Abstract
ADP/ATP carrier protein (AAC) is located in the mitochondrial inner membrane and has an important function in mitochondrial energy supply. This protein transports ATP to the cytoplasm and counter transports ADP into the mitochondria. J-2-N cardiomyopathic hamsters were investigated to determine the AAC content in cardiac mitochondria. After recording an electrocardiogram and collecting blood, the cardiac mitochondria were isolated. The mitochondrial membranes were labelled with eosin-5-maleimide (EMA) and separated on SDS polyacrylamide gels. The position of the AAC component was identified by exposing the gel under UV light, and the AAC content was determined by densitometry after staining with Coomassie blue. The AAC content ratio was significantly decreased in both 10-week-old and 1-year survived J-2-N hamsters when compared to control Golden hamster. Among 10-week-old J-2-N hamsters, the decrease in the AAC content ratio was more marked for the animals with more severe myocardial damage. The H(+)-ATPase activities of mitochondrial membrane were higher in 10-week-old J-2-N hamsters than in control hamsters. These results suggest that the decrease of AAC in J-2-N hamster plays an important role in the pathogenesis of cardiomyopathy in J-2-N hamsters.

Abstract
The procedure for the isolation from mitochondria of the undenatured ADP, ATP carrier is described. The condition of retaining the nativity are elaborated. 1. As indicator for the ADP, ATP carrier (35S)- or (3H) carboxyatractylate were used. By preloading the mitochondria with carboxyatractylate, a stable carboxyatractylate . protein complex could be retained after solubilization with Triton X-100. Among the polyoxyethylene detergents emulphogen is also solubilizing, whereas Brij and Lubrol fail to solubilize. 2. When unloaded mitochondria are solubilized the capacity for binding carboxyatractylate disappears rapidly, particularly at 20 degrees C. 3. When mitochondria are preloaded with atractylate, the binding after solubilization with Triton X-100 is considerably lower than with carboxyatractylate, indicating that the high affinity of carboxyatractylate is required for effectively protecting the protein. 4. For purification hydroxyapatite is most effective. The carboxyatractylate-protein complex appears in the pass-through whereas the bulk of other mitochondrial proteins are retained such that a 7-fold purification is obtained. The nonadsorptivity to hydroxyapatite is dependent on the undenatured state maintained in the carboxyatractylate . protein complex. 5. Subsequent gel filtration on Sepharose results in a 1.5-fold further enrichment of specific carboxyatractylate binding up to 17 mumol/g protein, corresponding to a 10-fold purification from mitochondria. This value cannot be increased with further measures. 6. At the last purification step, in sodium dodecyl sulfate polyacrylamide gel electrophoresis virtually a single band of 30 000 molecular weight is found, confirming the purity at this stage. A molecular weight of 60 000 is calculated from the carboxyatractylate binding, indicating that the carboxyatractylate protein complex consists of two 30 000 subunits. From this the protein share of the ADP, ATP carrier in beef heart mitochondria can be calculated to amount to 9.5%9 7. The intact carboxyatractylate . protein complex is protected against proteolytic degradation. The release of carboxyatractylate ensues a conformational change of protein as assayed by conformation specific antibodies, concomitant with unmasking of proteolytic site as assayed by tryptic digestion. 8. The amino acid composition indicates hydrophobicity (39% polarity) and a high content of basic amino acid such as lysine and arginine. There is 1.5 mol percent cysteine and a blocked N-terminal. 9. From the solubilized complex (35S) carboxyatractylate can be removed by carboxyatractylate, ADP and ATP but not by ITP, etc., indicating the presence of recognizing sites specific fof ADP, ATP and therefore, identity with the ADP, ATP carrier. 10. Other reported procedures for isolating the ADP, ATP carrier are shown to either fail or have lower yield than the present, original procedure.

Abstract
2,4,3',5'-tetrahydroxystilbene (THS) wa s found to inhibit rat liver mitochondrial adenosine triphosphatase (ATPase) activity induced by various concentrations of 2,4-dinitrophenol (DNP). The I50 was found to be 17 nmoles/mg mitochondrial protein. The maximum inhibitory effects of oligomycin and atractyloside on the DNP-activated mitochondrial ATPase activity can be enhanced by adding THS. The atractyloside-insensitive ATPase activity of Lubrol-treated rat liver mitochondria was also inhibited by low concentration of THS. The tetramethoxyderivative of THS was much less effective than the parent compound in depressing the ATPase activity of both intact and Lubrol-treated mitochondria. These observations suggest that the phenolic groups are essential for the mitochondrial actions of THS, and this compound most probably acts by a mechanism different from oligomycin on the mitochondrial ATPase complex.

Abstract
1. Functional properties of the ATPase complex are investigated in megamitochondria isolated from livers of weanling mice fed a diet containing 2% chloramphenicol, as an inhibitor of mitochondrial protein synthesis. 2. Whereas the specific activity of ATPase remains unchanged in chloramphenicol-induced megamitochondria, about 40% of the enyzme activity is resistant to inhibition by oligomycin, triethyltin or venturicidin. It is concluded that the ATPase complex lacks one or more components whose synthesis or accumulation is dependent on mitochondrial translation. The inhibitor-resistant ATPase portion appears tightly bound to the mitochondrial membrane. 3. Respiratory chain phosphorylation is tightly coupled in isolated megamitochondria. ATP synthesis and ATP-Pi exchange are diminished by 40%, as compared to control mitochondria, but both processes are sensitive to oligomycin, triethyltin or venturicidin. 4. The decrease in ATP synthesis and ATP-Pi exchange in megamitochondria correlates quite well with the emergence of inhibitor-resistant ATPase. 5. The following electron transport activities in the megmitochondria are reduced: NADH-cytochrome c reductase, by 60%, cytochrome oxidase, by 80%; the amount of antimycin required to gain complete inhibition of the bc1-segment is diminished by more than 50%. On the other hand succinate dehydrogenase activity is increased by 50%. 6. Chloramphenicol-induced megamitochondria appear to be a useful system for studying the role of mitochondrial translation in the assembly of mammalian mitochondria.

Abstract
1. In rat liver mitochondria bromothymol blue inhibited the exchange of [14C]succinate for succinate, malonate, L-malate and inorganic phosphate; the [14C]citrate/citrate and [14C]citrate/malate exchange reactions and the phosphate/hydroxyl exchange were also inhibited by this dye. The inhibition of the rate of succinate, citrate and phosphate uptake by bromothymol blue is found to be competitive. 2. The degree of inhibition by bromothymol blue of the ]14C]succinate/malonate exchange reaction was pH dependent. It has been shown that the inhibition increased linearly while the pH was increased from 6.0 to 8.2. However, the binding rate of bromothymol blue to the mitochondria decreased with the rising pH of the medium. It is concluded that the binding of acidic bromothymol blue was not essential for the inhibitory effect. 3. Other sulfonephthalein derivatives also inhibited [14C]succinate/malonate exchange reaction. At pH 7.2 the relative order of the strength of the inhibitory action of the sulfonephthalein compounds tested was: thymol blue greater than bronocresol green greater than bromothymol blue greater than phenol red greater than bromocresol purple. The results do not indicate any correlation between the pK values of pH values of pH indicators and their extents of inhibition. 4. It is suggested that the negatively charged bromothymol blue interacts with the positively charged centers of the anion carrier systems causing inhibition of membrane permeability for anions.

Abstract
Isolated inner mitochondrial membrane contains a small number of binding sites for atractyloside (of the order of 0.1 nmole/mg of protein) with very high binding affinity (half saturation at 0.014 &mgr;M atractyloside). The high affinity binding ability of the inner mitochondrial membrane is markedly decreased upon aging, acidification of the medium or addition of ADP, but remains unchanged in the presence of uncouplers such as FCCP. Added ADP causes a two-step transition from the high affinity binding to low affinity binding (K(d) > 0.50 &mgr;M) and concomitantly a significant increase of the measured number of binding sites (about a doubling). The half maximum effect in the first step transition is given by 1 &mgr;M ADP. The use of 35S-atractyloside as a probe of the inner mitochondrial membrane conformation specifically related to the adenine nucleotide translocation is discussed.
