Aldehyde oxidase-dependent marked species difference in hepatic metabolism of the sedative-hypnotic, zaleplon, between monkeys and rats. (1/144)

A marked difference in hepatic activity of aldehyde oxidase between rats and monkeys was found to be responsible for the previously reported marked species difference in the metabolism of Zaleplon in vivo. In the postmitochondrial fractions, S-9s, from liver homogenates of these animals, Zaleplon was transformed in the presence of NADPH into the side chain oxidation product, N-desethyl-Zaleplon, and the aromatic ring oxidation product, 5-oxo-Zaleplon. In the rat S-9, N-desethyl-Zaleplon and 5-oxo-Zaleplon were a major and a very minor metabolites, respectively. However, in the monkey S-9, Zaleplon was transformed into 5-oxo-Zaleplon at a much higher rate than that for N-desethyl-Zaleplon formation. N-Desethyl-Zaleplon was formed in the monkey S-9 at a rate almost equal to that in the rat S-9. N-Desethyl-5-oxo-Zaleplon was formed at a minor rate only in the monkey S-9 through N-desethyl-Zaleplon as an obligatory intermediate. The hepatic activity for the formation of 5-oxo-Zaleplon in the monkey and rat was localized in cytosol and did not require NADPH. Sensitivity to various inhibitors and requirement of water as oxygen source, using H218O, strongly suggested that the hepatic cytosolic formation of 5-oxo-Zaleplon was mediated by aldehyde oxidase. N-Desethyl-Zaleplon was formed in the presence of NADPH by microsomes from the liver of rats and monkeys, and its formation was strongly suggested using various cytochrome P-450 inhibitors to be mediated by a number of cytochrome P-450 isoforms, such as 3A, 2C, and 2D subfamilies.  (+info)

A genetic linkage map of rat chromosome 9 with a new locus for variant activity of liver aldehyde oxidase. (2/144)

A genetic linkage map of rat chromosome 9 consisting of five loci including a new biochemical marker representing a genetic variation of the activity of the liver aldehyde oxidase, (Aox) was constructed. Linkage analysis of the five loci among 92 backcross progeny of (WKS/Iar x IS/Iar)F1 x WKS/Iar revealed significant linkages between these loci. Minimizing crossover frequency resulted in the best gene order: Aox-D9Mit4-Gls-Cryg-Tp53l1. The homologues of the Cryg, Gls, and Aox genes have been mapped on mouse chromosome 1 and human chromosome 2q. The present findings provide further evidence for the conservation of synteny among these regions of rat, mouse, and human chromosomes.  (+info)

Molecular cloning of the cDNA coding for mouse aldehyde oxidase: tissue distribution and regulation in vivo by testosterone. (3/144)

The cDNA coding for mouse aldehyde oxidase (AO), a molybdoflavoprotein, has been isolated and characterized. The cDNA is 4347 nt long and consists of an open reading frame predicting a polypeptide of 1333 amino acid residues, with 5' and 3' untranslated regions of 13 and 335 nt respectively. The apparent molecular mass of the translation product in vitro derived from the corresponding cRNA is consistent with that of the monomeric subunit of the AO holoenzyme. The cDNA codes for a catalytically active form of AO, as demonstrated by transient transfection experiments conducted in the HC11 mouse mammary epithelial cell line. The deduced primary structure of the AO protein contains consensus sequences for two distinct 2Fe-2S redox centres and a molybdopterin-binding site. The amino acid sequence of the mouse AO has a high degree of similarity with the human and bovine counterparts, and a significant degree of relatedness to AO proteins of plant origin. Northern blot and in situ hybridization analyses demonstrate that hepatocytes, cardiocytes, lung endothelial or epithelial cells and oesophagus epithelial cells express high levels of AO mRNA. In the various tissues and organs considered, the level of AO mRNA expression is not strictly correlated with the amount of the corresponding protein, suggesting that the synthesis of the AO enzyme is under translational or post-translational control. In addition, we observed sex-related regulation of AO protein synthesis. In the liver of male animals, despite similar amounts of AO mRNA, the levels of the AO enzyme and corresponding polypeptide are significantly higher than those in female animals. Treatment of female mice with testosterone increases the amounts of AO mRNA and of the relative translation product to levels similar to those in male animals.  (+info)

Production of homo- and hetero-dimeric isozymes from two aldehyde oxidase genes of Arabidopsis thaliana. (4/144)

Polyclonal antibodies were raised against synthetic peptides or recombinant polypeptides encoded by Arabidopsis atAO-1 and atAO-2 cDNAs, which have sequences similar to maize and animal aldehyde oxidase (AO) cDNAs. Anti-atAO-1 antibodies recognized AOalpha and AObeta among the three isoforms, AOalpha, AObeta, and AOgamma, detected in Arabidopsis seedlings after native PAGE, while anti-atAO-2 antibodies reacted with AObeta and AOgamma. The polypeptide specifically recognized by each antibody was collected as the Protein-A/IgG/antigen complex. The 150- and 145-kDa polypeptides were purified by SDS-PAGE and digested with Achromobacter Protease I. From the amino acid sequences and molecular masses of the derivative peptides, it was revealed that the 150- and 145-kDa polypeptides were the products of atAO-1 and atAO-2, respectively. Molecular masses of the native forms of AOalpha, AObeta, and AOgamma were estimated as approximately 290-300 kDa. These results suggest that AOalpha and AOgamma are homodimers consisting of atAO-1 and atAO-2 products, respectively, and that AObeta is a heterodimer of the atAO-1 and atAO-2 products.  (+info)

Thioguanine administered as a continuous intravenous infusion to pediatric patients is metabolized to the novel metabolite 8-hydroxy-thioguanine. (5/144)

Thiopurine antimetabolites have been in clinical use for more than 40 years, yet the metabolism of thiopurines remains only partially understood. Data from our previous pediatric phase 1 trial of continuous i.v. infusion of thioguanine (CIVI-TG) suggested that TG was eliminated by saturable mechanism, with conversion of the drug to an unknown metabolite. In this study we have identified this metabolite as 8-hydroxy-thioguanine (8-OH-TG). The metabolite coeluted with the 8-OH-TG standard on HPLC and had an identical UV spectrum, with a lambda(max) of 350 nm. On mass spectroscopy, the positive ion, single quad scan of 8-OH-TG yielded a protonated molecular ion at 184 Da and contained diagnostic ions at m/z 167, 156, 142, and 125 Da. Incubation of TG in vitro with partially purified aldehyde oxidase resulted in 8-OH-TG formation. 8-OH-TG is the predominant circulating metabolite found in patients receiving CIVI-TG and is likely generated by the action of aldehyde oxidase.  (+info)

The mouse aldehyde oxidase gene: molecular cloning, chromosomal mapping and functional characterization of the 5'-flanking region. (6/144)

In this article, we report on the chromosome mapping and molecular cloning of the genetic locus encoding the mouse molybdo-iron/sulfur-flavoprotein aldehyde oxidase. The aldehyde oxidase locus maps to mouse chromosome 1 band C1-C2, as determined by fluorescence in situ hybridization experiments conducted on metaphase chromosomes. The gene is approximately 83 kb long and consists of 35 exons. The exon/intron boundaries are perfectly conserved relative to the corresponding human homolog and almost completely conserved relative to the mouse xanthine oxidoreductase gene. This further supports the concept that the aldehyde oxidase and xanthine oxidoreductase loci evolved from the same ancestral precursor by a gene duplication event. The position of a major transcription start site was defined by primer extension and RNase mapping analysis. The 5'-flanking region of the mouse aldehyde oxidase gene contains a functional and orientation-dependent promoter as well as several putative binding sites for known cell-specific and general transcription factors. Deletion analysis of the 5'-flanking region defines an approximately 470 bp DNA stretch which is necessary and sufficient for the transcription of the mouse aldehyde oxidase gene.  (+info)

Functional expression of two Arabidopsis aldehyde oxidases in the yeast Pichia pastoris. (7/144)

To investigate the biochemical and enzymatic properties of two aldehyde oxidase (AO) isoforms of Arabidopsis thaliana, we expressed AAO1 and AAO2 cDNAs in a heterologous yeast (Pichia pastoris) system and successfully obtained the proteins in active forms. The expressed AAO1 and AAO2 proteins gave activity bands with the same mobilities on native gel electrophoresis and exhibited the same substrate preferences on zymograms with 8 aldehydes as those of AOalpha and AOgamma in Arabidopsis seedlings, respectively. Furthermore, anti-AAO1 and anti-AAO2 antibodies, which specifically recognize the seedling AOalpha and AOgamma, respectively, reacted with the AAO1 and AAO2 proteins produced in P. pastoris, respectively. These results indicate that these AO proteins are accurately produced in the yeast system, as in Arabidopsis seedlings. Using AO preparations from P. pastoris, the enzymatic properties of Arabidopsis AOalpha and AOgamma were investigated. AOalpha showed a relatively wide substrate specificity for 7 aldehydes tested, with high affinity to benzaldehyde and indole-3-aldehyde, while AOgamma could most efficiently oxidize naphthaldehyde. AOalpha was strongly inhibited by iodoacetate and KCN, while AOgamma was inhibited not only by iodoacetate and KCN but also by 2-mercaptethanol, dithiothreitol, menadion, and estradiol. AOalpha and AOgamma showed the highest activity at around 65 and 50 degrees C, respectively, and exhibited pH dependence around pH 8.0. These results indicate that the two AO isoforms in Arabidopsis seedlings have different enzymatic properties and may have different physiological roles in vivo.  (+info)

Metabolism of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in perfused rat liver: involvement of hepatic aldehyde oxidase as a detoxification enzyme. (8/144)

To elucidate the toxicological relevance of hepatic aldehyde oxidase (AO) as a detoxification enzyme of 1-methyl-4-phenyl-1,2,3, 6-tetrahydropyridine (MPTP), we studied the metabolism and the hepatotoxicity of MPTP in intact rat livers exhibiting different AO activities by using a recirculating perfusion method. In the perfusate during a 90-min recirculation of 1 mM MPTP, the perfused liver from Jcl:Wistar rat, a strain showing high AO activity, generated almost equal amounts of 1-methyl-4-phenylpyridinium species (MPP(+)) and 1-methyl-4-phenyl-5,6-dihydro-2-pyridone (MPTP lactam) as major metabolites, together with 4-phenyl-1,2,3, 6-tetrahydropyridine, 1-methyl-4-phenyl-2-pyridone (MP 2-pyridone) and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine N-oxide. However, a marked decrease of MPTP lactam as well as MP 2-pyridone and a concomitant increase of MPP(+) were caused by coinfusion of 2-hydroxypyrimidine (2-OH PM), a competitive inhibitor of AO, into Jcl:Wistar rat liver. A quite similar metabolic profile was obtained on perfusion of AO-deficient WKA/Sea rat liver. Rather large amounts of MPP(+) were retained in the liver in all cases, but especially in Jcl:Wistar rat in the presence of 2-OH PM. Lactate dehydrogenase leakage into the perfusate from rat liver perfused with 1 mM MPTP was greater in the strain with lower AO activity, WKA/Sea, than in that with higher AO activity, Jcl:Wistar. Furthermore, inhibition of AO in Jcl:Wistar rat in the presence of 2-OH PM caused an enhancement of lactate dehydrogenase leakage. These results suggest that hepatic AO is a key detoxification enzyme for MPTP.  (+info)

TY - CHAP. T1 - Aldehyde Oxidases as Enzymes in Phase I Drug Metabolism. AU - Mota, Cristiano. AU - Santos-Silva, Teresa Sacadura. AU - Terao, Mineko. AU - Garattini, Enrico. AU - Romão, Maria João. AU - Leimkühler, Silke. PY - 2019/6/27. Y1 - 2019/6/27. N2 - This chapter discusses the significance of aldehyde oxidases for the design and development of new drugs, and discusses associated problems. Aldehyde oxidases are a group of enzymes with important functions in the context of drug and xenobiotic metabolism. Aldehyde oxidases (AOXs) and xanthine oxidoreductases (XORs) are structurally and evolutionarily linked molybdoflavoproteins. AOXs and XORs are widely distributed throughout all kingdoms of life, homologous proteins have been identified in many eukaryotic and prokaryotic organisms. The C-terminal domain III is binding the molybdenum cofactor (Moco) in its sulfido-containing form. At the catalytic site, the Moco adopts an approximately square pyramidal geometry. Heterologous expression ...
Aldehyde oxidase (AO; EC 1.2.3.1) catalyzes the final step of abscisic acid (ABA) biosynthesis, which is the oxidation of abscisic aldehyde (ABAld) to ABA. Gene expression analyses indicate that the stress-induced Pisum sativum PsAOγ isoform, which effectively uses ABAld as a substrate, is encoded by the PsAO3 gene. PsAO3 was heterologously expressed in Pichia pastoris and the recombinant PsAO3 protein revealed substrate preferences highly similar to the native PsAOγ protein present in the pea leaves and roots. Both proteins prefer indole-3-aldehyde and naphthaldehyde as substrates, although high activities against abscisic aldehyde and citral were also observed. The Km values of PsAO3 for naphthaldehyde and abscisic aldehyde (4.6 and 5.1 μM, respectively) were the lowest among the substrates tested. PsAO3 activity was almost completely inhibited by potassium cyanide, diphenyleneiodonium, and methanol. Rapidly imposed drought stress did not increase the level of PsAO3 mRNA or activity of any ...
Aldehyde oxidase (AOX) is a complex molybdoflavoprotein that belongs to a family of structurally related molybdoenzymes that bind the molybdenum cofactor (Moco) (Hille, 1996). AOX is homologous to xanthine oxidoreductase (XOR), another mammalian molybdoflavoenzyme, and both AOX and XOR show a remarkable degree of sequence similarity (Krenitsky, 1978; Garattini et al., 2003). AOX is active as a homodimer, and each 150-kDa monomer consists of three separate domains that bind different cofactors: the 20-kDa N-terminal domain binds two distinct [2Fe-2S] clusters, the 40-kDa central domain binds the FAD cofactor, and the 80-kDa C-terminal domain binds Moco (Garattini et al., 2008). Moco-containing enzymes are divided further into three different families, the xanthine oxidase (XO) family, the sulfite oxidase family, and the dimethyl sulfoxide reductase family, which are classified in accordance to the ligands at the molybdenum active site (Hille, 1996).. Members of the XOR family are characterized by ...
Aldehyde oxidase is a cytosolic drug-metabolizing enzyme that has been highlighted recently as playing a prominent role in the metabolism of heterocyclic-containing drug molecules (Pryde et al., 2010; Garattini and Terao, 2011, 2012; Hutzler et al., 2013). Numerous clinical programs have been impacted by rapid metabolism, and thus poor pharmacokinetics, because of aldehyde oxidase (Kaye et al., 1984; Dittrich et al., 2002; Akabane et al., 2011). One cause for the failure to predict the human pharmacokinetic properties of these AO substrates is the profound species differences noted for this enzyme. In particular, routine pharmacokinetic studies rat and dog in early drug discovery will likely not adequately capture AO-mediated contributions to metabolic clearance, because rats generally have low AO activity and dogs are devoid of activity (Beedham, 1987; Garattini et al., 2008). In a recently published review on aldehyde oxidase, it was reported that rhesus monkey and guinea pig may represent the ...

The Moco (molybdenum cofactor) sulfurase ABA3 from Arabidopsis thaliana catalyses the sulfuration of the Moco of aldehyde oxidase and xanthine oxidoreductase, which represents the final activation step of these enzymes. ABA3 consists of an N-terminal NifS-like domain that exhibits L-cysteine desulfurase activity and a C-terminal domain that binds sulfurated Moco. The strictly conserved Cys430 in the NifS-like domain binds a persulfide intermediate, which is abstracted from the substrate L-cysteine and finally needs to be transferred to the Moco of aldehyde oxidase and xanthine oxidoreductase. In addition to Cys⁴³⁰, another eight cysteine residues are located in the NifS-like domain, with two of them being highly conserved among Moco sulfurase proteins and, at the same time, being in close proximity to Cys⁴³⁰. By determination of the number of surface-exposed cysteine residues and the number of persulfide-binding cysteine residues in combination with the sequential substitution of each ...

Chem-Defenseâ ¢ is a nutrient blend formulated for persons with chemical sensitivities. Recent scientific research indicates that molybdenum, a trace mineral that activates the enzymes aldehyde oxidase and sulfite oxidase, may provide necessary nutritional support for chemically sensitive individuals. Glutathione (GSH) is a key element of the livers detoxifying process, and is also the precursor for glutathione peroxidase, a major free radical-scavenging enzyme. Ribolflavin is the precursor for FAD, a coenzyme which recycles used GSH. The benefit of the sublingual form is that it is absorbed directly into the bloodstream, via the blood vessels under the tongue and in the cheeks, allowing for quick entry into the system.
As the role of AO in metabolism of new drug molecules continues to emerge, it is critical that DMPK scientists have the most updated methodologies to enable formulation of a thorough experimental plan to understand the potential implications of this metabolic pathway.

Induction of nine-cis-epoxycarotenoid dioxygenase 6 (NCED6), an abscisic acid (ABA) biosynthesis gene, alone is sufficient to suspend germination in testa-ruptured seeds, which are at the final step of germination. Molecular consequences of NCED6 induction in imbibed seeds were investigated by RNA sequencing. The analysis identified many unknown and uncharacterized genes that were up-regulated by NCED6 induction, in addition to the major regulators of ABA signalling. Interestingly, other NCEDs were up-regulated by NCED6 induction, suggesting that the major rate-limiting enzymes in the ABA biosynthesis pathway are subject to positive-feedback regulation. ZEAXANTHIN EPOXIDASE and ABSCISIC ALDEHYDE OXIDASE3, which function upstream and downstream of NCED, were also up-regulated in seeds by NCED6 induction, which suggests that the distinct layers of positive feedback loops are coordinately operating in the NCED6-induced seeds. SOMNUS (SOM), which was also up-regulated by NCED6 induction, was the ...

Multiple exocyclic DNA adducts arise from reactions of lipid and DNA peroxidation products with DNA bases. These endogenous lesions are mutagenic; therefore, monitoring adduct levels may provide a means of assessing genomic exposure to oxidative damage in human populations. The metabolic processing of endogenously formed exocyclic DNA adducts has now been investigated for the purpose of developing non-invasive markers of oxidative damage. The pyrimidopurinone deoxynucleoside adduct, M1dG, was found to undergo enzymatic oxidation to produce 6-oxo-M1dG. The corresponding base adduct, M1G, was subject to sequential oxidation producing first 6-oxo-M1G and then 2,6-dioxo-M1G. The enzymes xanthine oxidoreductase (XOR) and aldehyde oxidase (AO) catalyzed the oxidation of M1dG and M1G. Additionally, the unsubstitued etheno base adduct, 1,N2-etheno-Gua, and the substituted etheno base adduct, heptanone-1,N2-etheno-Gua, were oxidized to produce 2-oxo-etheno-Gua and 2-oxo-hepatanone-etheno-Gua, ...

Reactive oxygen intermediates (ROI) are together with prostanoids, leukotrienes and proteases, believed to be the mediators of inflammation and responsible for the pathogenesis of tissue destruction in RA. Antioxidant (AO) activity is one of the mechanisms by which many conventional drugs used in day to day treatment of RA alleviate the painful symptoms associated with this disease. An investigation has been carried out to compare the antioxidant potentials of two polyherbal formulations, Maharasnadhi quathar (MRQ) and Weldehi choornaya (WC), used by Ayurvedic medical practitioners in Sri-Lanka for the treatment of RA patients. AO potentials of these preparations were assessed by their effects in RA patients on: (a) activities of the AO enzymes superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase; (b) lipid peroxidation (as estimated by thiobarbituric acid reacting substances (TBARS) generation); and (c) concentrations of serum iron and haemoglobin (Hb), and the total iron ...

WHAT DOES MOLYBDENUM DO FOR US?. There are enzymes that require molybdenum called molybdoenzymes. In humans there are three of these enzymes:. 1. Sulfite Oxidase which energizes the changing of sulfite to sulfate. This needs to be done so that sulfur containing amino acids such as methionine can be metabolized.. 2. Xanthine Oxidase starts the breakdown of nucleotides (the building blocks for DNA and RNA) which creates uric acid and uric acid is important to the bloods plasma antioxidant ability.. 3. Both Aldehyde Oxidase and Xanthine Oxidase energize the addition of hydrogen and oxygen molecules to certain molecules and both of them are involved in the metabolism of drugs and toxins in our bodies.. Only Sulfite Oxidase is absolutely necessary to human health.. WHAT HAPPENS WHEN WE DONT GET ENOUGH MOLYBDENUM?. In healthy people molybdenum deficiency doesnt exist as far as we know. Although, there are known problems in places where the soil has very low levels of minerals including ...
Antennae of the tobacco hornworm moths Manduca sexta contain an aldehyde oxidase (AOX) that oxidizes aldehydes to carboxylic acids. The enzyme, which is distinguishable from aldehyde-oxidizing activities in other tissues, is secreted into the receptor lymph that bathes the primary olfactory dendrites. First detectable about 3 d before eclosion, AOX levels increase through the first day after eclosion. This parallels the development of the antennal responsiveness to bombykal (a male attractant aldehydic pheromone produced by female M. sexta) and trans-2-hexenal (an aldehyde commonly found in leaves). The AOX is about 60% more abundant in antennae of males than in antennae of females. The antennal AOX is a dimer with Mr of 295 kDa and is capable of oxidizing a variety of aldehydes. Of all aldehydes examined, the pheromone bombykal was the best substrate with an apparent Km of 5 microM, whereas the next best substrate, benzaldehyde, had an apparent Km of 255 microM. Using kinetic parameters ...

Nicotine is of importance as the addictive chemical in tobacco, pharmacotherapy for smoking cessation, a potential medication for several diseases, and a useful probe drug for phenotyping cytochrome P450 2A6 (CYP2A6). We review current knowledge about the metabolism and disposition kinetics of nicotine, some other naturally occurring tobacco alkaloids, and nicotine analogs that are under development as potential therapeutic agents. The focus is on studies in humans, but animal data are mentioned when relevant to the interpretation of human data. The pathways of nicotine metabolism are described in detail. Absorption, distribution, metabolism, and excretion of nicotine and related compounds are reviewed. Enzymes involved in nicotine metabolism including cytochrome P450 enzymes, aldehyde oxidase, flavin-containing monooxygenase 3, amine N-methyltransferase, and UDP-glucuronosyltransferases are represented, as well as factors affecting metabolism, such as genetic variations in metabolic enzymes, ...

PY - 2015/1/1. Y1 - 2015/1/1. N2 - Aldehyde dehydrogenases (ALDHs) catalyse the conversion of toxic aldehydes into non-toxic carboxylic acids. Of the 21 ALDHs in mice, it is the ALDH3 family members (ALDH3A1, ALDH3A2, ALDH3B1, ALDH3B2 and ALDH3B3) that are responsible for the removal of lipid-derived aldehydes. However, ALDH3B2 and ALDH3B3 have yet to be characterized. In the present study, we examined the enzyme activity, tissue distribution and subcellular localization of ALDH3B2 and ALDH3B3. Both were found to exhibit broad substrate preferences from medium- to long-chain aldehydes, resembling ALDH3A2 and ALDH3B1. ...

But not too surprising to Dr. Karl-Hans Wurzinger, a DNA expert who testified in the case. You probably remember Dr. Wurzinger from his 1980 dissertation, Allozyme Variation in the African Freshwater Snail Genus Bulinus, if you werent already digging him after 1974s Phylogeny and Correlations of Aldehyde Oxidase, Xanthine Oxidase, Xanthine Dehydrogenase and Peroxidase in Animal Tissues, later made into a not-very-popular film. But he is also known for a 1997 paper on fraternal twins with different fathers.. Basically, this can happen if, in the course of about a week, one blessed event occurs, the female ovulates again, and then she has a second romantic partner who also hits the target. Scientists refer to it as heteropaternal superfecundation but it is known informally as Have None of These People Ever Heard of Birth Control Syndrome. Wikipedia says this is not uncommon in animals, for reasons that probably need not be explained, but Dr. Wurzinger found that it is relatively rare in ...
