Abstract
Chlorella vulgaris was cultivated in the gradually increased proportion of toxic sludge extracts for acclimation, which was obtained from SBR treated synthetic wastewater containing mixed chlorophenols (2,4,6-trichlorophenol and 4-chlorophenol). The growth of C. vulgaris was obviously improved after acclimation with the cell number in the 100% sludge group was 22.75±0.85∗106cellmL-1, which was relatively more than the BG11 control group's (20.80±0.35∗106cellmL-1) and apparently over the 100% sludge group (10.78±0.45∗106cellmL-1). Compared with the sludge control sludge group, C. vulgaris in the acclimation group gained 24.1% and 18.2% more relative removal rate about TOC and ecotoxicity, respectively. Proteomics analysis showed that protein spots were more clear and centralized and the clarifications of the different protein spots narrowed from 8 to 5 after acclimation. Proteins related to oxidoreducase activity and energy metabolism were over expressed and C. vulgaris could select the metabolic pathways, especially enhanced pyruvate fermentation, TCA cycle, and glycolysis after acclimation, by over accumulating the corresponding vital enzymes. Conclusively, acclimation was a good method to improve the removal ability and growth of C. vulgaris and algae could acclimatize itself to grow upon the toxic sludge extracts by metabolic selection. We suppose acclimation process was a potential method for algae wastewater treatment and algae cultivation without or reduce dilution.

Abstract
Mitochondrial nucleoside diphosphate kinase (NDPK-D; synonyms: NME4, NM23-H4) represents the major mitochondrial NDP kinase. The homohexameric complex emerged as a protein with multiple functions in bioenergetics and phospholipid signaling. It occurs at different but precise mitochondrial locations and can affect among other mitochondrial shapes and dynamics, as well as the specific elimination of defective mitochondria or cells via mitophagy or apoptosis. With these various functions in cell homeostasis, NDPK-D/NME4 adds to the group of so-called moonlighting (or gene sharing) proteins.

Abstract
Chlorella vulgaris was cultivated in varying proportions of toxic sludge extracts obtained from a sequencing batch reactor for treating synthetic wastewater containing chlorophenols. C. vulgaris could reduce the ecotoxicity from sludge extracts, and a positive correlation was noted between ecotoxicity removal and total organic carbon removal. In terms of cell density, the optimal proportion of sludge extracts required for the cultivation of C. vulgaris was lower than 50%. The correlation between protein content in per 106 algae and inhibition extent of ecotoxicity of the 5 groups on the day of inoculation (0.9182, p < .05) indicated a positive relationship between algal protein secretion and ecotoxicity. According to the protein expression and differential protein expression analysis, we concluded that C. vulgaris produced proteins that involved in the stress response/redox system and energy metabolism/biosynthesis to respond to the toxic environment and some other proteins related to mixotrophic metabolism.

Ocean acidification increases the accumulation of toxic phenolic compounds across trophic levels. Nat Commun 2015; 6:8714.

Abstract
Increasing atmospheric CO2 concentrations are causing ocean acidification (OA), altering carbonate chemistry with consequences for marine organisms. Here we show that OA increases by 46–212% the production of phenolic compounds in phytoplankton grown under the elevated CO2 concentrations projected for the end of this century, compared with the ambient CO2 level. At the same time, mitochondrial respiration rate is enhanced under elevated CO2 concentrations by 130–160% in a single species or mixed phytoplankton assemblage. When fed with phytoplankton cells grown under OA, zooplankton assemblages have significantly higher phenolic compound content, by about 28–48%. The functional consequences of the increased accumulation of toxic phenolic compounds in primary and secondary producers have the potential to have profound consequences for marine ecosystem and seafood quality, with the possibility that fishery industries could be influenced as a result of progressive ocean changes. Increasing atmospheric CO2 concentrations causes ocean acidification, which alters marine chemical environments with unknown consequences for marine ecosystems. Here, Gao et al. show that ocean acidification increases levels of phenolic compounds in phytoplankton and zooplankton, implying a food chain impact.

Abstract
Nucleoside diphosphate kinase (NDPK) is a key enzyme in the control of cellular concentrations of nucleoside triphosphates, and has been shown to play important roles in many cellular processes. In this work we investigated the subcellular localization of the canonical NDPK1 from Trypanosoma cruzi (TcNDPK1), the etiological agent Chagas's Disease, and evaluated the effect of adding an additional weak protein-protein interaction domain from the green fluorescent protein (GFP). Immunofluorescence microscopy revealed that the enzyme from wild-type and TcNDPK1 overexpressing parasites has a cytosolic distribution, being the signal more intense around the nucleus. However, when TcNDPK1 was fused with dimeric GFP it relocalizes in non-membrane bounded granules also located adjacent to the nucleus. In addition, these granular structures were dependent on the quaternary structure of TcNDPK1 and GFP since mutations in residues involved in their oligomerization dramatically decrease the amount of granules. This phenomenon seems to be specific for TcNDPK1 since other cytosolic hexameric enzyme from T. cruzi, such as the NADP(+)-linked glutamate dehydrogenase, was not affected by the fusion with GFP. In addition, in parasites without GFP fusions granules could be observed in a subpopulation of epimastigotes under metacyclogenesis and metacyclic trypomastigotes. Organization into higher protein arrangements appears to be a singular feature of canonical NDPKs; however the physiological function of such structures requires further investigation.

Abstract
Nucleoside diphosphate kinase (NDK), which is widely conserved in both prokaryotes and eukaryotes, maintains a balanced pool of nucleotide triphosphates and their deoxy derivatives. NDKs from bacterial and other systems contain the conserved HGSD motif, where the His residue is required for the biochemical activities, namely the NTPase (AT-Pase and GTPase), NTP synthesising, and autophosphorylation activities of the enzyme. Amino acid sequence homology comparison of the NDK of Mycobacterium smegmatis (MsmNDK) with the NDKs of other bacterial genera showed the presence of H117GSD motif. While the recombinant wild type MsmNDK showed the NTPase, NTP synthesising, and autophosphorylation activities, the H117Q mutation abolished the biochemical activities of the recombinant MsmNDK-H117Q mutant protein in vitro. These observations demonstrate that the H117 residue in the HGSD motif is required for the biochemical activities of MsmNDK.

Abstract
Trypanosomatids are responsible for economically important veterinary affections and severe human diseases. In Africa, Trypanosoma brucei causes sleeping sickness or African trypanosomiasis, while in America, Trypanosoma cruzi is the etiological agent of Chagas disease. These parasites have complex life cycles which involve a wide variety of environments with very different compositions, physicochemical properties, and availability of metabolites. As the environment changes there is a need to maintain the nucleoside homeostasis, requiring a quick and regulated response. Most of the enzymes required for energy management are phosphotransferases. These enzymes present a nitrogenous group or a phosphate as acceptors, and the most clear examples are arginine kinase, nucleoside diphosphate kinase, and adenylate kinase. Trypanosoma and Leishmania have the largest number of phosphotransferase isoforms ever found in a single cell; some of them are absent in mammals, suggesting that these enzymes are required in many cellular compartments associated to different biological processes. The presence of such number of phosphotransferases support the hypothesis of the existence of an intracellular enzymatic phosphotransfer network that communicates the spatially separated intracellular ATP consumption and production processes. All these unique features make phosphotransferases a promising start point for rational drug design for the treatment of human trypanosomiasis.

Abstract
Nucleoside diphosphate kinase (NDPK/Nm23), responsible for intracellular di- and triphosphonucleoside homeostasis, plays multiple roles in cellular energetics, signaling, proliferation, differentiation and tumor invasion. The only human NDPK with a mitochondrial targeting sequence is NDPK-D, the NME4 gene product, which is a peripheral protein of mitochondrial membranes. Subfractionation of rat liver and HEK 293 cell mitochondria revealed that NDPK-D is essentially bound to the inner membrane. Surface plasmon resonance analysis of the interaction using recombinant NDPK-D and model liposomes showed that NDPK-D interacts electrostatically with anionic phospholipids, with highest affinity observed for cardiolipin. Mutation of the central arginine (Arg-90) in a surface-exposed basic RRK motif unique to NDPK-D strongly reduced interaction with anionic phospholipids. Due to its symmetrical hexameric structure, NDPK-D was able to cross-link anionic phospholipid-containing liposomes, suggesting that NDPK-D could promote intermembrane contacts. Latency assays with isolated mitochondria and antibody binding to mitoplasts indicated a dual orientation for NDPK-D. In HeLa cells, stable expression of wild type but not of the R90D mutant led to membrane-bound enzyme in vivo. Respiration was significantly stimulated by the NDPK substrate TDP in mitochondria containing wild-type NDPK-D, but not in those expressing the R90D mutant, which is catalytically equally active. This indicates local ADP regeneration in the mitochondrial intermembrane space and a tight functional coupling of NDPK-D with oxidative phosphorylation that depends on its membrane-bound state.

Abstract
We describe a method for the detection and quantification of nucleoside diphosphate kinase (NDPK). NDPK catalyzes the transfer of the gamma-phosphate of cytidine 5'-triphosphate on uridine 5'-diphosphate (UDP) to produce uridine 5'-triphosphate (UTP). The method uses a nonradioactive coupled enzyme assay in which UTP produced by NDPK is utilized by UDP-glucose pyrophosphorylase. This latter enzyme synthesizes UDP-glucose and inorganic phosphate in the presence of glucose 1-phosphate. UDP-glucose is detected at 260 nm after separation of the reaction mixture by high-performance liquid chromatography (HPLC) on a strong anion-exchange column. The assay is reliable, specific, and linear with respect to time and enzyme amount. Using 15 min incubation time, the method allows detection of NDPK activity below 10 pmol/min. It can be used to analyze kinetic behavior and to quantify NDPK from a wide variety of animal, microbial, and plant sources. It also provides an alternative to radiometric assays and an improvement on pyruvate kinase-linked spectrophotometric assays, which can be hampered by pigments present in crude extracts. Furthermore, we show that the HPLC method developed here can be directly used to assay enzymes for which UDP-glucose is a product.
