Nucleoside diphosphate-linked moiety X motif 8; Probably mediates the hydrolysis of some nucleoside diphosphate derivatives; Nudix hydrolase family (236 aa)

ADP-sugar pyrophosphatase; Enzyme that can either act as an ADP-sugar pyrophosphatase in absence of diphosphate or catalyze the synthesis of ATP in presence of diphosphate. In absence of diphosphate, hydrolyzes with similar activities various modified nucleoside diphosphates such as ADP-ribose, ADP-mannose, ADP-glucose, 8-oxo-GDP and 8-oxo-dGDP. Can also hydrolyze other nucleotide sugars with low activity. In presence of diphosphate, mediates the synthesis of ATP in the nucleus by catalyzing the conversion of ADP-ribose to ATP and ribose 5- phosphate. Nuclear ATP synthesis takes place [...] (219 aa)

Protein Asterix; WD repeat domain 83 opposite strand (106 aa)

8-oxo-dGDP phosphatase NUDT18; Mediates the hydrolyzis of oxidized nucleoside diphosphate derivatives. Hydrolyzes 8-oxo-7,8-dihydroguanine (8- oxo-Gua)-containing deoxyribo- and ribonucleoside diphosphates to the monophosphates. Hydrolyzes 8-oxo-dGDP and 8-oxo-GDP with the same efficiencies. Hydrolyzes also 8-OH-dADP and 2-OH-dADP. Exhibited no or minimal hydrolyzis activity against 8-oxo-dGTP, 8- oxo-GTP, dGTP, GTP, dGDP and GDP. Probably removes oxidized guanine nucleotides from both the DNA and RNA precursor pools; Belongs to the Nudix hydrolase family (323 aa)

Peroxisomal coenzyme A diphosphatase NUDT7; Coenzyme A diphosphatase which mediates the cleavage of CoA, CoA esters and oxidized CoA with similar efficiencies, yielding 3’,5’-ADP and the corresponding 4’-phosphopantetheine derivative as products. CoA into 3’,5’-ADP and 4’- phosphopantetheine. Has no activity toward NDP-sugars, CDP- alcohols, (deoxy)nucleoside 5’-triphosphates, nucleoside 5’-di or monophosphates, diadenosine polyphosphates, NAD, NADH, NADP, NADPH or thymidine-5’-monophospho-p-nitrophenyl ester. May be required to eliminate oxidized CoA from peroxisomes, or regulate CoA [...] (238 aa)

Nucleoside diphosphate-linked moiety X motif 17; Probably mediates the hydrolysis of some nucleoside diphosphate derivatives; Nudix hydrolase family (328 aa)

tRNA 2’-phosphotransferase 1; Catalyzes the last step of tRNA splicing, the transfer of the splice junction 2’-phosphate from ligated tRNA to NAD to produce ADP-ribose 1’’-2’’ cyclic phosphate; Belongs to the KptA/TPT1 family (255 aa)

Nucleotide triphosphate diphosphatase NUDT15; May catalyze the hydrolysis of nucleoside triphosphates including dGTP, dTTP, dCTP, their oxidized forms like 8-oxo-dGTP and the prodrug thiopurine derivatives 6-thio-dGTP and 6-thio-GTP. Could also catalyze the hydrolysis of some nucleoside diphosphate derivatives. Hydrolyzes oxidized nucleosides triphosphates like 8-oxo-dGTP in vitro, but the specificity and efficiency towards these substrates are low. Therefore, the potential in vivo sanitizing role of this enzyme, that would consist in removing oxidatively damaged forms of nucleosides t [...] (164 aa)
