-
structure of poly(ADP-ribose) glycohydrolase (PARG) in complex with the poly(ADP-ribose) (PAR) substrate reveals that PARG-PAR contacts are provided almost exclusively by the macrodomain. The accessory domain (which is part of the PARG catalytic region) has only limited interaction with PAR, but it structurally supports the PARG catalytic loop and may have an important role in regulation of PARG catalytic activity. The PARG-PAR structure also reveals that PARGs preferably bind PAR at the chain termini and primarily act as exo-glycohydrolases (whereby PARG sequentially degrades terminal ADP-ribose units). While binding along the PAR chain and endo-glycohydrolytic cleavage of PAR is structurally possible, it appears to be less efficient. Due to active site constraints and the conformation of bound PAR, canonical PARGs are unlikely to efficiently bind the aforementioned putative PAR branch sites

Mg2+
required for catalysis, binuclear Mg2+ site, structure overview. The distal ribose of poly(ADP-ribose), enabling the hydroxyl groups of the distal ribose to coordinate the two Mg2+ ions. MgA is coordinated with Asp314, Asp316, Thr317, three hydroxyl groups of the distal ribose and water 269. Meanwhile, MgB is coordinated with the 2'-hydroxyl group of the distal ribose, Thr76, Asp77, Asp78, Asp316, and two water molecules (water 269 and water 85). The sequence alignment and structural comparison reveals that the Mg2+ coordinating acidic residues Asp77, Asp78, Asp314, and Asp316 are fully conserved in homologous ARH enzymes. Both Mg2+ ions are involved in the positioning of water 351 in the catalytic center through hydrogen-bonding interaction. the binding pocket of ARH3 is divided into two subunits by the binuclear Mg2+ sites

RBPI-3
a rhodanine-containing mammalian PARG inhibitor, enzyme-inhibitor structure analysis, overview. RBPI-3 binds predominantly via a pi-pi stacking interaction with Tyr296 and the conserved Phe398. To accommodate the binding of RBPI-3, Phe398 moves into the adenosine binding pocket. The RBPI-3 carboxyl moiety occupies a region corresponding to the ADP-ribose alpha-phosphate group and H-bonds to main chain atoms of Lys365 and Gln254. The RBPI-3 di-chlorobenzyl moiety extends into the solvent and is disordered

malfunction
-
osmotic (mannitol treatment) or oxidative (methyl viologen treatment) stress reduces germination rates of the mutant parg1-3 seeds compared with wild type seeds. The parg1-3 plants show reduced tolerance to drought (withholding water), osmotic, and oxidative stress, as well as increased levels of cell damage under osmotic and oxidative stress and reduced survival under drought stress when compared with the wild type plants. Stomata of the parg1-3 plants fail to close under drought stress conditions

malfunction
-
knockout mutants of isozyme PARG110 show resistance to photoreceptor degeneration, the mutant retina is morphologically and functionally undistinguishable from wild-type. Absence of PARG110 disrupts the poly-ADP-ribose polymerase activation
malfunction
lack of poly(ADPribose) glycohydrolase activity in Vero and A549 host cells, achieved by chemical inhibition or iRNA, produces the reduction of the percentage of infected cells as well as the number of amastigotes per cell and trypomastigotes released, leading to a nearly complete abrogation of the infection process
malfunction
-
poly(ADP-ribose) glycohydrolase loss-of-function causes increased Hrp38 poly(ADP-ribosyl)ation and also results in the rough-eye phenotype with disrupted ommatidial lattice and and bristles and reduced number of photoreceptor cells. Hrp38 is essential for fly eye development. Parg mutant eye clones have decreased expression level of DE-cadherin with orientation defects, which is reminiscent of DE-cadherin mutant eye phenotype. The Parg mutant eye accumulates a large amount of poly(ADP-ribose)
malfunction
-
RNAi knockdown of PARG or pretreatment with 2-((R)-2-methylpyrrolidin-2-yl)-1H-benzimidazole-4-carboxamide (ABT-888), meaning an increase in poly(ADP-ribose) level, lead to increased HeLa cell death in N-methyl-N'-nitro-N-nitrosoguanidine-treated HeLa cells. The effect can be reduced by PARP-1 inhibitors. Combination of poly(ADP-ribose) polymerase-1 and poly(ADP-ribose) glycohydrolase inhibition in chemotherapy does not produce increased HeLa cell death
malfunction
-
silencing of endogenous enzyme expression causes inhibition of TGFbeta-mediated transcription. This can be relieved after simultaneous depletion of poly(ADP-ribose) polymerase 1
malfunction
a deficiency in PARG glycohydrolase activity prolongs DNA damage foci, containing PAR, and similarly delays DNA repair, causing hypersensitivity to DNA damaging agents and selective killing of repair-deficient tumors such as BRCA mutated breast cancers-deficient cancer cells in a manner similar to PARP inhibition
malfunction
disruption of DrPARG expression causes accumulation of endogenous poly-ADP-ribose (PAR) and compromises recovery from UV radiation damage. Endogenous PAR levels in Deinococcus radiodurans are elevated after UV irradiation, indicating that the prokaryotic PARylation may be involved in resistance to genotoxic stresses
malfunction
mutation of PARG1 results in increased DNA damage level and enhanced cell death in plants after bleomycin treatment. Inhibition or silencing of PARPs improves abiotic stress tolerance, enhancing resistance to drought, high light, heat and oxidative stresses, and perturbs innate immune responses to microbe-associated molecular patterns such as flg22 and elf18, resulting in a compromised basal defense response. Phenotypic comparison of the loss-of-function mutants of all PARP and PARG genes in Arabidopsis thaliana, overview. Loss-of-PARG1 leads to the transcriptional up-regulation of DNA repair genes and increase of cellular DNA damage level. The parg1 mutants show only yellow instead of green seedlings with reduced fresh weight compared to wild-type. The parg1-4 mutant root is more sensitive to bleomycin than that of wild-type Col-0
malfunction
PARG inhibition increases endogenous DNA damage, stalls replication forks and increases homologous recombination, and the lack of homologous recombination (HR) proteins at PARG inhibitor-induced stalled replication forks induces cell death. siRNA screen for increased DNA damage with PARG depletion. Model whereby inhibition or depletion of PARG leads to fork stalling and fork aberrations, resulting in signalling and recruitment of HRR proteins for repair. Therefore in the absence of these homologous recombination repair (HRR) proteins, PARG depleted or inhibited cells cannot survive
malfunction
poly(ADP-ribose) glycohydrolase (PARG) silencing suppresses benzo(a)pyrene induced cell transformation. Benzo(a)pyrene (BaP) is a ubiquitously distributed environmental pollutant and known carcinogen, which can induce malignant transformation in cells. PARG silencing dramatically reduces DNA damages, chromosome abnormalities, and micronuclei formations in the PARG-deficient human bronchial epithelial cells compared to the control 16HBE cells. PARG silencing down-regulates cell colony formation induced by BaP, reduces BaP-induced genomic instability, and protects cells from BaP-induced DNA damage
malfunction
poly(ADP-ribosyl) glycohydrolase (PARG) depletion affects cell proliferation and DNA synthesis, leading to replication-coupled H2AX phosphorylation. PARG depletion or inhibition per se slows down individual replication forks similarly to mild chemotherapeutic treatment. Electron microscopic analysis of replication intermediates reveals marked accumulation of reversed forks and single-stranded DNA (ssDNA) gaps in unperturbed PARG-defective cells. PARG-defective cells display both ataxia-telangiectasia-mutated (ATM) and ataxia-Rad3-related (ATR) activation, as well as chromatin recruitment of standard double-strand-break-repair factors, such as 53BP1 and RAD51, but no physical evidence for chromosomal breakage. PARG-deficient cell phenotype, detailed overview. PARG depletion results in slow replication fork progression even in the absence of genotoxic treatments. PARG downregulation and inhibition lead to similar phenotypic consequences

Endogenous PARP-1 and the enzyme have opposing roles on TGFbeta-induced gene expression, overview
metabolism
poly(ADP-ribosyl)ation is a reversible post-translational modification of proteins, characterized by the addition of poly(ADP-ribose) (PAR) to proteins by poly(ADP-ribose) polymerase (PARP), and removal of PAR by poly(ADP-ribose) glycohydrolase (PARG). Three PARPs and two PARGs have been found in Arabidopsis thaliana. PARG1 and PARG2 play an essential and a minor role, respectively under the same conditions

physiological function
-
generation of A549 lung adenocarcinoma cell lines with stably suppressed PARG and poly(ADP-ribose) polymerase PARP-1 expression, i.e. shPARG and shPARP1 cell lines, respectively. shPARG cells accumulate large amounts of poly-(ADP-ribosyl)ated proteins and exhibit reduced PARP activation. Hydrogen peroxide-induced cell death is regulated by PARG in a dual fashion. Whereas the shPARG cell line is resistant to the necrotic effect of high concentrations of hydrogen peroxide, these cells exhibit stronger apoptotic response. Both shPARP1 and especially shPARG cells display a delayed repair of DNA breaks and exhibit reduced clonogenic survival following hydrogen peroxide treatment. Translocation of apoptosis-inducing factor cannot be observed, but cells can be saved by methyl pyruvate and alpha-ketoglutarate
physiological function
-
homozygous T-DNA knockout line parg1 seedlings exhibit exaggerated seedling growth inhibition and pigment accumulation in response to elf18 and are hypersensitive to the DNA-damaging agent mitomycin C. Both parg1 and parg2 knockout plants show accelerated onset of disease symptoms when infected with Botrytis cinerea. Cellular levels of ADP-ribose polymer increase after infection with avirulent Pseudomonas syringae pv tomato DC3000 avrRpt2+, and pathogen-dependent changes in the poly(ADP-ribosyl)ation of discrete proteins are also observed
physiological function
-
stable knock-down of poly(ADP-ribose) polymerase PARP-1 and PARG. The majority of genes affected by the knockdown of one factor are similarly affected by the knockdown of the other factor. The most robustly regulated common genes are enriched for stress-response and metabolic functions. PARP-1 and PARG localize to the promoters of positively and negatively regulated target genes. The levels of chromatin-bound PARG at a given promoter generally correlate with the levels of PARP-1 across the subset of promoters tested. For about half of the genes tested, the binding of PARP-1 at the promoter is dependent on the binding of PARG. PARP-1 and PARG enzymatic activities are required for some, but not all, target genes
physiological function
-
Arabidopsis poly(ADP-ribose) glycohydrolase 1 is required for drought, osmotic and oxidative stress responses
physiological function
-
at higher levels of DNA damage, the coordinate activities of PARPs-1/2 and PARG can rapidly deplete the pool of cellular NAD(H), facilitating the release of mitochondrial proteins through signaling pathways that promote cell death
physiological function
-
coordinate regulation of PARP-1 and -2 and PARG is required for cellular responses to genotoxic stress
physiological function
-
poly(ADP-ribose)glycohydrolase is an upstream regulator of Ca2+ fluxes in oxidative cell death. Transient receptor potential 2 is the primary Ca2+ channel for cell death signaling under poly(ADP-ribose)glycohydrolase control
physiological function
-
by regulating the hydrolytic arm of poly(ADP-ribosyl)ation, the enzyme participates in a number of biological processes, including the repair of DNA damage, chromatin dynamics, transcriptional regulation, and cell death. Role of silencing of the enzyme in DNA methylation pattern changed by benzo(a)pyrene, a carcinogen cytotoxic which can trigger extensive cellular responses
physiological function
-
causal involvement of wild-type isozyme PARG110 in the process of photoreceptor degeneration. Contrasting its anticipated role as a functional antagonist, absence of PARG110 correlated with low PARP activity, suggesting that PARG110 and PARP1 act in a positive feedback loop, which is especially active under pathologic conditions
physiological function
poly(ADP-ribose) glycohydrolase (PARG) represents the main poly(ADP-D-ribose) hydrolyzing activity in the cell to ADP-ribose units. The enzyme is crucial for Trypanosoma cruzi infection cycle in the human host cell. Both, Trypanosoma cruzi and the human host, poly(ADP-ribose) glycohydrolase activities are important players in the life cycle of Trypanosoma cruzi

poly(ADP-ribose) glycohydrolase catalyzes the removal of poly(ADP-ribose) chains from posttranslationally modified proteins by hydrolysis of alpha(122-22) O-glycosidic linkages, functioning as an endo-glycosidase to release oligo(ADP-ribose) and as an exo-glycosidase to release ADP-ribose
physiological function
poly(ADP-ribosyl)ation is a crucial regulator of cell fate in response to genotoxic stress, poly(ADP-ribose) degradation is carried out mainly by poly(ADP-ribose) glycohydrolase, role of poly(ADP-ribose) glycohydrolase in the regulation of cell fate in response to benzo(a)pyrene, overview
physiological function
protein poly(ADP-ribosyl)ation regulates a number of important cellular processes. Poly(ADP-ribose) glycohydrolase is the primary enzyme responsible for hydrolyzing the poly(ADP-ribose) polymer in vivo
physiological function
-
the enzyme activity regulates cellular poly(ADP-ribose) level. Since the enzyme cannot cleave the terminal ADP-ribose unit at the protein bound to glutamate residues, the residual activities of MacroD2 and TARG1 may contribute to the accumulation of poly(ADP-D-ribose)in the Parg knockout animals
physiological function
-
the enzyme is responsible for the degradation of poly(ADP-ribose) (PAR) polymers
physiological function
the reversion of poly(ADP-ribosyl)ation is catalysed by poly(ADP-ribose) glycohydrolase, which specifically targets the unique PAR (1''-2') ribose-ribose bonds
physiological function
a single poly(ADP-ribosyl) glycohydrolase (PARG) mediates PAR degradation. PARG prevents the accumulation of unusual replication structures during unperturbed S phase. Role of PARG in the replication of human chromosomes. PAR degradation is essential to promote resumption of replication at endogenous and e-exogenous lesions, preventing idle recruitment of repair factors to remodeled replication forks
physiological function
degradation of poly(ADP-ribose), PAR, is catalyzed by poly(ADP-ribose) glycohydrolase (PARG) by endo- and exoglycosidase reactions that release products of variable length and ADPribose monomers. The poly(ADP-ribosyl) glycohydrolase, PARG, protein of Fusarium oxysporum f. sp. lycopersici is involved in DNA repair and does not act in pathogenicity as an effector. The organism encodes for only one PARG enzyme, and this is responsible for the total cellular PARG activity
physiological function
enzyme ARH3 is a multifunctional enzyme that also hydrolyzes poly(ADP-ribose) (ADPR). Enzyme ARH3 plays a role in DNA damage repair. The recruitment of ARH3 to DNA lesions is mediated by ADPR recognition. The catalytic mechanism of protein ADP-ribose hydrolases can be classified into two different groups, namely metal-dependent and metal-independent catalysis. ARHs, such as ARH3, belong to metal-dependent catalysis, utilizing two Mg2+ ions and acidic residues to complete the catalytic reaction, which might be highly conserved. In contrast, the catalytic mechanism is not conserved in the macrodomain ADP-ribose hydrolases, For example, Glu756 and a water molecule act together to catalyze the reaction in PARG, whereas the key catalytic factor in MacroD2 is an activated water. The charge characteristic of the binding pocket in ARH3 is remarkably distinguished from that in PARG. The binding pocket of PARG, accommodating the ADPR dimer, is mostly composed of the basic region
physiological function
enzyme ARH3 is a multifunctional enzyme that also hydrolyzes poly(ADP-ribose) (PAR). ARH3 can specifically hydrolyze PAR, mono-ADP-ribose post-translational modifications (MARPTMs), and O-acetyl-ADP-ribose. For all these substrates, ARH3 preferentially hydrolyzes the scissile alpha-O-linkage attached to the anomeric C1'' position of ADPR. In mammals, two enzymes, ADP-ribosyl-acceptor hydrolase 3 (ARH3 or ADPRHL2) and PAR glycohydrolase (PARG), function in tandem to reverse PARylation. These hydrolytic enzymes commonly cleave the alpha(1''-2') O-glycosidic linkages in PAR chains. ARH3 appears to catalyze primarily exocytic cleavage of PAR, generating free ADPR. It is reported that ARH3 protects cells from oxidative stress-induced parthanatos by lowering the cytoplasmic PAR level. ARH3 is a distinctive, multitasking enzyme that controls two biologically important NAD+-dependent cellular signaling pathways
physiological function
PARG1 has poly(ADP-ribose) (PAR)-degrading activity and regulates poly(ADP-ribose) level in vivo. PARG1 and PARG2 play an essential and a minor role, respectively under the same conditions. PARG1 expression is induced primarily in root and shoot meristems by bleomycin and induction of PARG1 is dependent on ATM and ATR kinases. PARG1 antagonistically modulates the DNA repair process by preventing the over-induction of DNA repair genes. PARG1 plays a critical role in this process. Roles of PARP1 and PARP2 in DNA damage signaling. Induction of PARG1 gene is ATM- and ATR-dependent and PARG1 represses the transcriptional upregulation of ATM, ATR and SOG1. ATM and ATR are two critical kinases which transduce double and single strand break signals to DNA repair machinery, respectively. They phosphorylate the transcription factor SOG1, which then induces the expression of DNA repair genes
physiological function
poly(ADP-ribosyl)ation (PARylation) is a transient posttranslational modification that generates a signaling mechanism with diverse roles within molecular and cellular processes. PAR chains remaining from DNA repair are broken down by the enzyme poly(ADP-ribose) glycohydrolase (PARG). PARG catalyzes the hydrolysis of endo- and exoglycosidic bonds within the poly(ADP-ribose) (PAR) polymers
physiological function
poly(ADP-ribosyl)ation is a common post-translational modification that mediates a wide variety of cellular processes including DNA damage repair, chromatin regulation, transcription, and apoptosis, involving interactions of PAR with poly(ADP-ribose) glycohydrolase (PARG) and other binding proteins
physiological function
poly(ADP-ribosylation) of proteins follows DNA damage. Like addition of poly(ADP-ribose) (PAR) by poly(ADP-ribose) polymerase (PARP), removal of PAR by PARG is also thought to be required for repair of DNA strand breaks and for con-tinued replication at perturbed forks. Poly(ADP-ribose) glycohydrolase (PARG) has endo- and exoglycosidase activities which can cleaveglycosidic bonds, rapidly reversing the action of PARP enzymes. The functions of PARP and PARG may not be completely identical
physiological function
poly(ADPribose) glycohydrolase (PARG) is the primary enzyme that catalyzes the degradation of poly (ADP-ribose) (PAR), it plays an important role in regulating DNA damage repair and maintaining genomic stability
physiological function
the enzyme poly(ADP-ribose) glycohydrolase (PARG) performs a critical role in the repair of DNA single strand breaks (SSBs). Critical to this repair process is the orderly degradation of PAR chains. The roles of PARG and poly(ADP-ribose) polymerase (PARP) are closely intertwined
physiological function
the PAR posttranslational modification by itself is a high affinity ligand for XRCC1, requiring a minimum chain length of 7 ADP-ribose units in the oligo(ADP-ribose) ligand for a stable interaction with XRCC1. This discrete binding interface enables the poly(ADP-ribose) (PAR) glycohydrolase (PARG) to completely disassemble the PARP1-XRCC1 complex without assistance from a mono(ADP-ribose) glycohydrolase. XRCC1 and other PAR-binding proteins mediate many of the downstream responses to PARP1 activation in the face of DNA damage. PARG rapidly reverses the PARylation of PARP1 and efficiently disassembles the PARP1-XRCC1 complex, thereby uncoupling the DNA repair scaffolding activities of XRCC1 from PARP1, which is targeted for proteasomal degradation after recruiting XRCC1 to sites of DNA damage. Ability of PARG to regulate the PARP1-XRCC1 interaction by converting PARylated PARP1 into MARylated PARP1, which retains a terminal ADP-ribose modification but does not bind to XRCC1
physiological function
the poly(ADP-ribose) glycohydrolase (PARG) endo-glycohydrolase activity may become significant in vivo at high PAR/PARG ratios (for example, in the case of an extreme cellular insult), thus releasing free PAR fragments to mediate apoptotic signaling

hypomorphic mouse model in which exons 2 and 3 of PARG gene have been deleted. Mutants exhibits nuclear localization of the enzyme which contains a catalytic domain but lacks the N-terminal region. Following DNA damage induced by N-methyl-N'-nitro-N-nitrosoguanidine, activity of both poly(ADP-ribose) glycohydrolase and poly(ADP-ribose) polymerase in mutant cell increases. Increase in poly(ADP-ribose) glycohydrolase activity leads to decrease in poly(ADP-ribose) polymerase-1 automodification resulting in increased activity. Mutant cells also show reduced formation of XCRR1 foci, delayed H2AX phosphorylation, decreased DNA break intermediates during repair, and increased cell death
