Abstract
Introduction Despite the critical role of programmed cell death (PCD) in plant development and defense responses, its regulation is not fully understood. It has been proposed that mitochondria may be important in the control of the early stages of plant PCD, but the details of this regulation are currently unknown. Methods We used Arabidopsis thaliana cell suspension culture, a model system that enables induction and precise monitoring of PCD rates, as well as chemical manipulation of this process to generate a quantitative profile of the alterations in mitochondrial and cytosolic proteomes associated with early stages of plant PCD induced by heat stress. The cells were subjected to PCD-inducing heat levels (10 min, 54°C), with/without the calcium channel inhibitor and PCD blocker LaCl3. The stress treatment was followed by separation of cytosolic and mitochondrial fractions and mass spectrometry-based proteome analysis. Results Heat stress induced rapid and extensive changes in protein abundance in both fractions, with release of mitochondrial proteins into the cytosol upon PCD induction. In our system, LaCl3 appeared to act downstream of cell death initiation signal, as it did not affect the release of mitochondrial proteins, but instead partially inhibited changes occurring in the cytosolic fraction, including upregulation of proteins with hydrolytic activity. Discussion We characterized changes in protein abundance and localization associated with the early stages of heat stress-induced PCD. Collectively, the generated data provide new insights into the regulation of cell death and survival decisions in plant cells.

Toward understanding the emergence of life: A dual function of the system of nucleotides in the metabolically closed autopoietic organization. Biosystems 2023; 224:104837. [PMID: 36649884 DOI: 10.1016/j.biosystems.2023.104837] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 01/05/2023] [Accepted: 01/10/2023] [Indexed: 01/15/2023]
Abstract
General structure of metabolism includes the reproduction of catalysts that govern metabolism. In this structure, the system becomes autopoietic in the sense of Maturana and Varela, and it is closed to efficient causation as defined by Robert Rosen. The autopoietic maintenance and operation of the catalysts takes place via the set of free nucleotides while the synthesis of catalysts occurs via the information encoded by the set of nucleotides arranged in polymers of RNA and DNA. Both energy charge and genetic information use the components of the same pool of nucleoside triphosphates, which is equilibrated by thermodynamic buffering enzymes such as nucleoside diphosphate kinase and adenylate kinase. This occurs in a way that the system becomes internally stable and metabolically closed, which initially could be realized at the level of ribozymes catalyzing basic metabolic reactions as well as own reproduction. The function of ATP, GTP, UTP, and CTP is dual, as these species participate both in the general metabolism as free nucleotides and in the transfer of genetic information via covalent polymerization to nucleic acids. The changes in their pools directly impact both bioenergetic pathways and nucleic acid turnover. Here we outline the concept of metabolic closure of biosystems grounded in the dual function of nucleotide coenzymes that serve both as energetic and informational molecules and through this duality generate the autopoietic performance and the ability for codepoietic evolutionary transformations of living systems starting from the emergence of prebiotic systems.

Abstract
The enzyme phosphoribosyl pyrophosphate synthase (PRPS) catalyzes the conversion of ribose 5-phosphate into phosphoribosyl diphosphate; the latter is a precursor of purine and pyrimidine nucleotides. Here, we investigated the function of PRPS from the single-celled green alga Chlamydomonas reinhardtii in its response to DNA damage from gamma radiation or the alkylating agent LiCl. CrPRPS transcripts were upregulated in cells treated with these agents. We generated CrPRPS-overexpressing transgenic lines to study the function of CrPRPS. When grown in culture with LiCl or exposed to gamma radiation, the transgenic cells grew faster and had a greater survival rate than wild-type cells. CrPRPS overexpression enhanced expression of genes associated with DNA damage response, namely RAD51, RAD1, and LIG1. We observed, from transcriptome analysis, upregulation of genes that code for key enzymes in purine metabolism, namely ribonucleoside-diphosphate pyrophosphokinase subunit M1, adenylate kinase, and nucleoside-diphosphate kinase. We conclude that CrPRPS may affect DNA repair process via regulation of de novo nucleotide synthesis.

Abstract
BACKGROUND NME23/NDPKs are well conserved proteins found in all living organisms. In addition to being nucleoside diphosphate kinases (NDPK), they are multifunctional enzymes involved in different processes such as DNA stability, gene regulation and DNA repair among others. TcNDPK1 is the canonical NDPK isoform present in Trypanosoma cruzi, which has nuclease activity and DNA-binding properties in vitro. OBJECTIVES In the present study we explored the role of TcNDPK1 in DNA damage responses. METHODS TcNDPK1 was expressed in mutant bacteria and yeasts and over-expressed in epimastigotes. Mutation frequencies, tolerance to genotoxic agents and activity of DNA repair enzymes were evaluated. FINDINGS Bacteria decreased about 15-folds the spontaneous mutation rate and yeasts were more resistant to hydrogen peroxide and to UV radiation than controls. Parasites overexpressing TcNDPK1 were able to withstand genotoxic stresses caused by hydrogen peroxide, phleomycin and hidroxyurea. They also presented less genomic damage and augmented levels of poly(ADP)ribose and poly(ADP)ribose polymerase, an enzyme involved in DNA repair. MAIN CONCLUSION These results strongly suggest a novel function for TcNDPK1; its involvement in the maintenance of parasite’s genome integrity.

Thermodynamic buffering, stable non-equilibrium and establishment of the computable structure of plant metabolism. PROGRESS IN BIOPHYSICS AND MOLECULAR BIOLOGY 2018; 146:23-36.

Abstract
The equilibria of coenzyme nucleotides and substrates established in plant cells generate simple rules that govern the plant metabolome and provide optimal conditions for the non-equilibrium fluxes of major metabolic processes such as ATP synthesis, CO2 fixation, and mitochondrial respiration. Fast and abundant enzymes, such as adenylate kinase, carbonic anhydrase or malate dehydrogenase, provide constant substrate flux for these processes. These "buffering" enzymes follow the Michaelis-Menten (MM) kinetics and operate near equilibrium. The non-equilibrium "engine" enzymes, such as ATP synthase, Rubisco or the respiratory complexes, follow the modified version of MM kinetics due to their high concentration and low concentration of their substrates. The equilibrium reactions serve as control gates for the non-equilibrium flux through the engine enzymes establishing the balance of the fluxes of load and consumption of metabolic components. Under the coordinated operation of buffering and engine enzymes, the concentrations of free and Mg-bound adenylates and of free Mg2+ are set, serving as feedback signals from the adenylate metabolome. Those are linked to various cell energetics parameters, including membrane potentials. Also, internal levels of reduced and oxidized pyridine nucleotides are established in the coordinated operation of malate dehydrogenase and respiratory components, with proton concentration as a feedback from pyridine nucleotide pools. Non-coupled pathways of respiration serve to equilibrate the levels of pyridine nucleotides, adenylates, and as a pH stat. This stable non-equilibrium organizes the fluxes of energy spatially and temporally, controlling the rates of major metabolic fluxes that follow thermodynamically and kinetically defined computational principles.

Abstract
Like pathogens, galling insects deliver effectors into plant tissues that induce gall formation. The gall midge Mayetiola destructor, also called Hessian fly, can convert a whole wheat seedling into a gall by inducing the formation of nutritive cells at the feeding site, inhibiting wheat growth, and reprogramming metabolic pathways of the attacked plants. Here we demonstrated the identification of a secreted Hessian fly protein, the nucleoside diphosphate kinase (NDK), in infested wheat plants through liquid chromatography-tandem mass spectrometry (LC-MS/MS) and western blots. In association with the NDK presence, enzymatic activity of NDK increased significantly in wheat tissues at the feeding site. In addition, there was a sudden increase in ATP abundance at the feeding site of infested susceptible wheat seedlings 24 h following Hessian fly larval infestation. Even though a direct link between cause and effect remains to be established, our data points to the direction that Hessian fly larvae injected NDK into wheat tissues as an effector protein, which plays a role in manipulating host plants and converting the plants into galls.

Abstract
Nucleoside diphosphate kinases (NDPK) are key enzymes involved in the intracellular nucleotide maintenance in all living organisms, especially in trypanosomatids which are unable to synthesise purines de novo. Four putative NDPK isoforms were identified in the Trypanosoma cruzi Chagas, 1909 genome but only two of them were characterised so far. In this work, we studied a novel isoform from T. cruzi called TcNDPK3. This enzyme presents an atypical N-terminal extension similar to the DM10 domains. In T. cruzi, DM10 sequences targeted other NDPK isoform (TcNDPK2) to the cytoskeleton, but TcNDPK3 was localised in glycosomes despite lacking a typical peroxisomal targeting signal. In addition, TcNDPK3 was found only in the bloodstream trypomastigotes where glycolytic enzymes are very abundant. However, TcNDPK3 mRNA was also detected at lower levels in amastigotes suggesting regulation at protein and mRNA level. Finally, 33 TcNDPK3 gene orthologs were identified in the available kinetoplastid genomes. The characterisation of new glycosomal enzymes provides novel targets for drug development to use in therapies of trypanosomatid associated diseases.

Abstract
The nuclear isoform of nucleoside diphosphate kinase isoenzyme NDPK-In undergoes strong catalytic activation upon its interaction with the active form of phytochrome A (Pfr) in red light. The autophosphorylation or intermolecular transphosphorylation of NDPK-In leads to the formation of phosphoester bonds stable in acidic solution. The phosphate residue of the phosphamide bond in the active center of NDPK-In can also be transferred to serine and threonine residues localized in other proteins, including phytochrome A. Phytochrome A, similarly to NDPK-In, undergoes autophosphorylation on serine and threonine residues and can phosphorylate some potential substrate proteins. The physical interaction between phytochrome A in the Pfr form and NDPK-In results in a significant increase in the kinase activity of NDPK-In. The results presented in this work indicate that NDPK-In may function as a protein kinase regulated by light.

Abstract
One frontier in synthetic biology seeks to move artificially expanded genetic information systems (AEGIS) into natural living cells and to arrange the metabolism of those cells to allow them to replicate plasmids built from these unnatural genetic systems. In addition to requiring polymerases that replicate AEGIS oligonucleotides, such cells require metabolic pathways that biosynthesize the triphosphates of AEGIS nucleosides, the substrates for those polymerases. Such pathways generally require nucleoside and nucleotide kinases to phosphorylate AEGIS nucleosides and nucleotides on the path to these triphosphates. Thus, constructing such pathways focuses on engineering natural nucleoside and nucleotide kinases, which often do not accept the unnatural AEGIS biosynthetic intermediates. This, in turn, requires assays that allow the enzyme engineer to follow the kinase reaction, assays that are easily confused by ATPase and other spurious activities that might arise through "site-directed damage" of the natural kinases being engineered. This article introduces three assays that can detect the formation of both natural and unnatural deoxyribonucleoside triphosphates, assessing their value as polymerase substrates at the same time as monitoring the progress of kinase engineering. Here, we focus on two complementary AEGIS nucleoside diphosphates, 6-amino-5-nitro-3-(1'-β-D-2'-deoxyribofuranosyl)-2(1H)-pyridone and 2-amino-8-(1'-β-D-2'-deoxyribofuranosyl)-imidazo[1,2-a]-1,3,5-triazin-4(8H)-one. These assays provide new ways to detect the formation of unnatural deoxyribonucleoside triphosphates in vitro and to confirm their incorporation into DNA. Thus, these assays can be used with other unnatural nucleotides.

Abstract
The study is the first to reveal the proteomic response in plants to a single PAH stress, and indicates that NDPK3 is a positive regulator in the Arabidopsis response to phenanthrene stress. Polycyclic aromatic hydrocarbons (PAHs) are highly carcinogenic pollutants that are byproducts of carbon-based fuel combustion, and tend to persist in the environment for long periods of time. PAHs elicit complex, damaging responses in plants, and prior research at the physiological, biochemical, and transcriptional levels has indicated that reactive oxygen species (ROS) and oxidative stress play major roles in the PAH response. However, the proteomic response has remained largely unexplored. This study hypothesized that the proteomic response in Arabidopsis thaliana to phenanthrene, a model PAH, would include a strong oxidative stress signature, and would provide leads to potential signaling molecules involved. To explore that proteomic signature, we performed 2D-PAGE experiments and identified 30 proteins levels that were significantly altered including catalases (CAT), ascorbate peroxidase (APX), peroxiredoxins (POD), glutathione-S-transferase, and glutathione reductase. Also upregulated was nucleoside diphosphate kinase 3 (NDPK-3), a protein known to have metabolic and stress signaling functions. To address whether NDPK-3 functions upstream of the oxidative stress response, we measured levels of stress-responsive enzymes in NDPK-3 overexpressor, loss-of-function knockout, and wild-type plant lines. In the NDPK-3 overexpressor, the enzyme activities of APX, CAT, POD, as well as superoxide dismutase were all increased compared to wild type; in the NDPK-3 knockout line, these enzymes had reduced activity. This pattern occurred in untreated as well as phenanthrene-treated plants. These data support a model in which NDPK-3 is a positive regulator of the Arabidopsis stress response to PAHs.

Abstract
Nucleoside diphosphate kinase (NDPK) is a ubiquitous enzyme found in all organisms and cell types, which catalyzes the transfer of the phosphoryl group from a nucleoside triphosphate to a nucleoside diphosphate. The gene encoding for NDPK from Drosophila melanogaster was amplified from the genomic DNA. The recombinant NDPK (rNDPK) was overexpressed in Escherichia coli and purified to homogeneity by Ni-NTA agarose affinity chromatography, HiTrap SP HP cation exchange chromatography and HiLoad 16/60 Superdex 200 gel filtration chromatography. The gel filtration chromatography and analytical ultracentrifugation showed that rNDPK was a trimer in solution. The binding affinity of NDPs with rNDPK, measured by isothermal titration calorimetry, indicated that the purines nucleotides show higher binding affinity compared with pyrimidines. The rNDPK had a definite nuclease activity in vitro, which could cleave supercoiled plasmid DNA, but had no effect on dsDNA and ssDNA. Furthermore, the structure for NDPK was determined by using the sitting drop vapor diffusion method. In the final model, the asymmetric unit is made of three molecules, each of which consists of a four-stranded anti-parallel β-sheets and seven α-helices. Sequence alignment and structure comparison illustrated that the simulated nucleotide-binding active site are conserved.

Abstract
This review describes the five nucleoside diphosphate kinase (NDPK) genes found in both model plants Arabidopsis thaliana (thale cress) and Oryza sativa L. (rice). Phylogenetic and sequence analyses of these genes allow the definition of four types of NDPK isoforms with different predicted subcellular localization. These predictions are supported by experimental evidence for most NDPK types. Data mining also provides evidence for the existence of a novel NDPK type putatively localized in the endoplasmic reticulum. Phylogenic analyses indicate that plant types I, II, and III belong to the previously identified Nme group I whereas type IV belongs to Nme group II. Additional analysis of the literature offers clues supporting the idea that the various plant NDPK types have different functions. Hence, cytosolic type I NDPKs are involved in metabolism, growth, and stress responses. Type II NDPKs are localized in the chloroplast and mainly involved in photosynthetic development and oxidative stress management. Type III NDPKs have dual targeting to the mitochondria and the chloroplast and are principally involved in energy metabolism. The subcellular localization and precise function of the novel type IV NDPKs, however, will require further investigations.

Exp Parasitol 2014; 142:43-50. [PMID: 24768953 DOI: 10.1016/j.exppara.2014.04.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2013] [Revised: 03/28/2014] [Accepted: 04/17/2014] [Indexed: 10/25/2022]
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
Green globular bodies were developed from Poncirus trifoliata L. root tip explants as a response to addition in the substrate of different growth regulators. From the globular bodies, shoots initiated and grew. Median section of the globular bodies reveals that they are composed of parenchyma cells and originate from the pericycle. The activity of DNases during shoot formation from globular bodies was influenced by the type and concentration of plant growth regulators that were added in the nutrient substrate. Peptide bands formation was also influenced by the increase of BA concentration. Consequently, BA, NAA and IAA combination influenced 5'-triphosphonucleosides (NTPs) appearance and activity in the presence of metal. Peptide bands resulted from the electrophoretic analysis of endogenous protein phosphorylation, proved to be catalytic subunits of NDP kinases, as they all phosphorylate diphosphonucleosides. The enzymes DNases and NDP kinases could be used as a scientific tool for the study of shoot formation from P. trifoliata L. green globular bodies.

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
Two isoforms of NDPKs (diphosphonucleoside kinases: E.C. 2.7.4.6.) named S-NDPK-A and S-NDPK-B were separated and purified from shoots of Alyssum murale (19th day of growth), a nickel accumulator plant, by a four-step procedure involving ammonium sulphate precipitation and DEAE-sepharose and hydroxyapatite column chromatography. Shoot NDPKs underwent autophosphorylation, proved thermostable, displayed similar molecular mass of 105,000, and consisted of six catalytic subunits. The size of subunits of S-NDPK-A and S-NDPK-B were 18 and 16kDa, respectively. The autophosphorylated S-NDPK-A and S-NDPK-B displayed isoelectric points (pI) of 5.8 and 6.6, respectively. The shoot NDPKs using NDPs (diphosphonucleosides) as substrates were metal dependent, while these underwent autophosphorylation in the absence of metal. The specificity of S-NDPK-A, S-NDPK-B and root NDPK-B (R-NDPK-B); towards mixtures of purino- and pyrimidino-NDPs were tested by TLC (thin layer chromatography). UDP and CDP (pyrimidino-NDPs) and GDP (purino-NDP) were exclusively phosphorylated, using (gamma-(32)P) ATP as phosphate donor, by S-NDPK-A and R-NDPK-B, respectively. Both purino- and pyrimidino-NDPs were phosphorylated by S-NDPK-B. The above isoforms also displayed differences in preference towards a mixture of ADP, GDP, dGDP, TDP, dCDP, CDP and UDP in the presence of Cu(2+), Zn(2+), Mg(2+), Mn(2+), Ni(2+), Ca(2+), Hg(2+) or Co(2+). For example, GDP was mainly phosphorylated by R-NDPK-B independently of the metal used, TDP was mainly phosphorylated by S-NDPK-A in the presence of Mg(2+), Mn(2+), Ca(2+) or Co(2+) and S-NDPK-B was capable of phosphorylating more or less independently of the metal used. The purified and characterized NDPK isoforms may play different biological roles according to their preference towards NDPs.

Abstract
Here, we analyze how the set of nucleotides in the cell is equilibrated and how this generates simple rules that help the cell to organize itself via maintenance of a stable non-equilibrium state. A major mechanism operating to achieve this state is thermodynamic buffering via high activities of equilibrating enzymes such as adenylate kinase. Under stable non-equilibrium, the ratios of free and Mg-bound adenylates, Mg(2+) and membrane potentials are interdependent and can be computed. The adenylate status is balanced with the levels of reduced and oxidized pyridine nucleotides through regulated uncoupling of the pyridine nucleotide pool from ATP production in mitochondria, and through oxidation of substrates non-coupled to NAD(+) reduction in peroxisomes. The set of adenylates and pyridine nucleotides constitutes a generalized cell energy status and determines rates of major metabolic fluxes. As the result, fluxes of energy and information become organized spatially and temporally, providing conditions for self-maintenance of metabolism.

Abstract
It was found that in medium with low ionic strength nucleoside diphosphate kinase (NDPK) solubilization from the outer membrane of liver mitochondria could be partially reversed by the addition of 3.3 mM MgCl2. Complete rebinding of the enzyme after the addition of MgCl2 was observed when the mitochondrial washing and storage medium contained leupeptin, an inhibitor of cathepsins. It was demonstrated that leupeptin and another inhibitor of cysteine proteinases, E-64, do not influence the rate of NDPK solubilization as well as its solubilized and membrane-associated activity. We conclude that NDPK becomes sensitive to proteolysis only after its solubilization; proteolysis does not affect the part of the enzyme molecule that is responsible for catalysis. After solubilization of NDPK in the absence of leupeptin, cathepsins damage sites of its binding on the membranes. The rate of the enzyme solubilization is dependent on the pH of the storage medium (pH 6.0-8.0); it decreases with increase in pH. It was shown that in the medium with high ionic strength, MgCl2 does not reverse pH-dependent NDPK solubilization, but solubilization could be reversed by increase in medium pH in the presence of E-64 and BSA. The physiological importance of these results is discussed.

Abstract
The analysis of the Acanthamoeba polyphaga mimivirus genome revealed the first virus-encoded nucleoside diphosphate kinase (NDK), an enzyme that is central to the synthesis of RNA and DNA, ubiquitous in cellular organisms, and well conserved among the three domains of life. In contrast with the broad specificity of cellular NDKs for all types of ribo- and deoxyribonucleotides, the mimivirus enzyme exhibits a strongly preferential affinity for deoxypyrimidines. In order to elucidate the molecular basis of this unique substrate specificity, we determined the three-dimensional (3D) structure of the Acanthamoeba polyphaga mimivirus NDK alone and in complex with various nucleotides. As predicted from a sequence comparison with cellular NDKs, the 3D structure of the mimivirus enzyme exhibits a shorter Kpn loop, previously recognized as a main feature of the NDK active site. The structure of the viral enzyme in complex with various nucleotides also pinpointed two residue changes, both located near the active site and specific to the viral NDK, which could explain its stronger affinity for deoxynucleotides and pyrimidine nucleotides. The role of these residues was explored by building a set of viral NDK variants, assaying their enzymatic activities, and determining their 3D structures in complex with various nucleotides. A total of 26 crystallographic structures were determined at resolutions ranging from 2.8 A to 1.5 A. Our results suggest that the mimivirus enzyme progressively evolved from an ancestral NDK under the constraints of optimizing its efficiency for the replication of an AT-rich (73%) viral genome in a thymidine-limited host environment.

Abstract
Here, we present the characterization of a trypanosomatid nucleoside diphosphate kinase (TcNDPK1) exhibiting nuclease activity. This is the first identification of a NDPK with this property in trypanosomatid organisms. The recombinant TcNDPK1 protein cleaves not only linear DNA, but also supercoiled plasmid DNA. Additionally, TcNDPK1 is capable of degrading Trypanosoma cruzi genomic DNA. ATP or ADP did not affect the nuclease activity, while the absence of Mg2+ completely inhibits this activity. NDPK and nuclease activities were inhibited at the same temperature, suggesting the presence of related catalytic sites. Furthermore, phenogram analysis showed that TcNDPK1 is close to Drosophila melanogaster and human NDPKs. The unspecific nuclease activity could suggest a participation in cellular processes such as programmed cell death.
