physiological function
NUDX7 contributes to 23% of the total diphosphohydrolase activity toward ADP-ribose under normal conditions, while under oxidative stress, the contribution of NUDX7 to the activity increases to 34%. Additionally, NUDX7 accounts for 53% of the total pyrophosphohydrolase activity toward NADH under normal conditions and the activity is increased by oxidative stress with NUDX7 contributing 57%

NO stimulates non-enzymatic ADP-ribosylation, at cysteine residues in the presence of reductant, of NUDT5 using ADP-ribose and consequently activates its ADPRase activity. ADPRase activity in J774 macrophage cells is increased by the treatment with SNP, an exogenous NO generator, or TNF-alpha/IFN-gamma, endogenous NO inducers. NO has a regulatory role, overview

LITERATURE
substrate-docking to zebrafish wild-type protein, and H97A mutant point to a role of His-97 in catalysis by orientation, and to a bidentate water bridging the dinuclear metal center as the potential nucleophile
gadolinium derivative, to 2.0 A resolution. The crystal structure of DR2204 consists of the conserved alpha/beta/alpha sandwich fold typical of Nudix hydrolases, the Nudix box, residues 94-115, holding the alpha1 helix sits between two loops accessible to the solvent, while the other two helices, alpha2 and alpha3, lie on the other side of the central beta-sheet and participate in dimer-interface formation
hanging-drop vapor diffusion at 18°C. The structure of the apo enzyme, the active enzyme and the complex with ADP-ribose are determined to 1.9 A, 2.7 A and 2.3 A, respectively. The Nudix motif residues, folded as a loop-helix-loop tailored for diphosphate hydrolysis, compose the catalytic center
-
purified recombinant enzyme in complex with the product AMP and Mn2+ ions in its Nudix active site, sitting drop vapor diffusion method, 20°C, 0.001 ml of 15 mg/ml protein solution is mixed with an equal volume of reservoir solution containing 0.1 M Tris, pH 7.5, 200 mM MgCl2, and 19% PEG 3350, with or without 30 mM AMP, equilibration against the reservoir, X-ray diffraction structure determination and analysis at 2.3 A resolution, molecular replacement method
purified recombinant wild-type and truncated mutant NUDT5 in complex with a non-hydrolyzable ADPR analogue, alpha,beta-methyleneadenosine diphosphoribose, and three Mg2+ ions representing the transition state of the enzyme during catalysis, 20 mg/ml protein is incubated with 5 mM AMPCPR and 10 mM MgCl2 at 4 °C overnight, followed by hanging drop vapour diffusion method, wild-type enzyme in complex with AMPCPR, and truncation mutant DELTAhNUDT5 in complex with AMPCPR and Mg2+, 4 °C, mixing of equal volumes of the protein solution and the reservoir solution containing 250 mM NaAc, 100 mM Tris-HCl, pH 8.0, and 29% PEG 4000, ingle crystals of the plate-shape morphology grow after 1 month, X-ray diffraction structure determination and anaylsis at 2.0 A resolution, molecular modelling
-
substrate docking on a homology model suggests possible interactions of ADP-ribose with seven residues located, with one exception (Cys253), either within the metallo-dependent phosphatases signature (Gln27, Asn110, His111), or in unique structural regions of the ADPRibase-Mn family: s2s3 (Phe37 and Arg43) and h7h8 (Phe210), around the active site entrance. Residue Phe37 is needed for ADP-ribose preference without catalytic effect. Arg43 is essential for catalysis. Cys253 is hindering for cADPR phosphohydrolase
purified recombinant His-tagged enzyme in complex with co-purified NAD and diphosphate complexed in the NadM-domain active site, and with ADPR substrate complexed in the Nudix-domain, hanging drop vapor diffusion method, 0.0015 ml of 15 mg/ml protein solution is mixed with an equal volume of reservoir solution containing 100 mM Tris, pH 7.5, and 1.5 M Li2SO4, 20°C, 3 days to 2 weeks, X-ray diffraction structure determination and analysis at 2.6 A resolution, selenomethionyl MAD phasing method

Ndx2 alone and in complex with Mg2+, with Mg2+ and AMP, and with Mg2+ and a nonhydrolyzable ADPR analogue, hanging-drop vapor diffusion method, 20 mg/ml protein in 20 mM Tris-HCl, pH 8.0, and 100 mM KCl, 0.001 ml of protein solution is mixed with the equal volume of reservoir solution and equilibrated against the reservoir, containing 0.1 M MES, pH 6.5, 0.16 M sodium acetate or magnesium acetate for the complexed enzyme, 14% PEG 8000, and 20% glycerol, at 20°C, soaking of crystals in 50 mM KAu(CN)2, X-ray diffraction structure determination and anaylsis at 2.0 A resolution, MAD phasing, model building, and refinement

to 2.16 A resolution. The crystal structure shows an unusual asymmetric dimer, with three domains for each chain. The C-terminal domain harbors the nicotinamide mononucleotide deamidase activity. The N-terminal domain belongs to the COG1058 family and is associated with the ADP-ribose diphosphatase activity. The mechanism for the ADP-ribose diphosphatase reaction involves a rotation of the COG1058 domain dimer as part of the reaction cycle

C253A
mutant displays a tenfold increased efficiency for cADP-ribose, with no or modest effect on the other substrates
D133A
