Efficient conversion of aromatic and phenylpropanoid alcohols to acids by the cascade biocatalysis of alcohol and aldehyde dehydrogenases. Synth Syst Biotechnol 2024; 9:187-195. [PMID: 38385148 PMCID: PMC10876487 DOI: 10.1016/j.synbio.2024.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 12/24/2023] [Accepted: 01/19/2024] [Indexed: 02/23/2024] Open
Abstract
Benzyl and phenylpropanoid acids are widely used in organic synthesis of fine chemicals, such as pharmaceuticals and condiments. However, biocatalysis of these acids has received less attention than chemical synthesis. One of the main challenges for biological production is the limited availability of alcohol dehydrogenases and aldehyde dehydrogenases. Environmental microorganisms are potential sources of these enzymes. In this study, 129 alcohol dehydrogenases and 42 aldehyde dehydrogenases from Corynebacterium glutamicum, Pseudomonas aeruginosa, and Bacillus subtilis were identified and explored with various benzyl and phenylpropanoid alcohol and aldehyde substrates, among which four alcohol dehydrogenases and four aldehyde dehydrogenases with broad substrate specificity and high catalytic activity were obtained. Moreover, a cascade whole-cell catalytic system including ADH-90, ALDH-40, and the NAD(P)H oxidase LreNox was established, which showed high efficiency in converting cinnamyl alcohol and p-methylbenzyl alcohol into the respective carboxylic acids. Remarkably, this biocatalytic system can be easily scaled up to gram-level production, facilitating preparation purposes.

Abstract
Oxidoreductases are enzymes with distinctive characteristics that favor their use in different areas, such as agriculture, environmental management, medicine, and analytical chemistry. Among these enzymes, oxidases, dehydrogenases, peroxidases, and oxygenases are very interesting. Because their substrate diversity, they can be used in different biocatalytic processes by homogeneous and heterogeneous catalysis. Immobilization of these enzymes has favored their use in the solution of different biotechnological problems, with a notable increase in the study and optimization of this technology in the last years. In this review, the main structural and catalytical features of oxidoreductases, their substrate specificity, immobilization, and usage in biocatalytic processes, such as bioconversion, bioremediation, and biosensors obtainment, are presented.

Abstract
Achromobacter species colonization of Cystic Fibrosis respiratory airways is an increasing concern. Two adult patients with Cystic Fibrosis colonized by Achromobacter xylosoxidans CF418 or Achromobacter ruhlandii CF116 experienced fatal exacerbations. Achromobacter spp. are naturally resistant to several antibiotics. Therefore, phages could be valuable as therapeutics for the control of Achromobacter. In this study, thirteen lytic phages were isolated and characterized at the morphological and genomic levels for potential future use in phage therapy. They are presented here as the Achromobacter Kumeyaay phage collection. Six distinct Achromobacter phage genome clusters were identified based on a comprehensive phylogenetic analysis of the Kumeyaay collection as well as the publicly available Achromobacter phages. The infectivity of all phages in the Kumeyaay collection was tested in 23 Achromobacter clinical isolates; 78% of these isolates were lysed by at least one phage. A cryptic prophage was induced in Achromobacter xylosoxidans CF418 when infected with some of the lytic phages. This prophage genome was characterized and is presented as Achromobacter phage CF418-P1. Prophage induction during lytic phage preparation for therapy interventions require further exploration. Large-scale production of phages and removal of endotoxins using an octanol-based procedure resulted in a phage concentrate of 1 × 109 plaque-forming units per milliliter with an endotoxin concentration of 65 endotoxin units per milliliter, which is below the Food and Drugs Administration recommended maximum threshold for human administration. This study provides a comprehensive framework for the isolation, bioinformatic characterization, and safe production of phages to kill Achromobacter spp. in order to potentially manage Cystic Fibrosis (CF) pulmonary infections.

Abstract
Bacterial cellulose is one of the most promising biomaterials for the development of a wide array of novel biotechnological solutions. Nevertheless, the commercial production of bacterial cellulose is still a challenge and obtaining novel strains presenting increased cellulose biosynthesis and stress resistance properties is of extreme importance. This work demonstrates the increased stress resistance, cellulose production abilities, and overall genomic properties of Komagataeibacter uvaceti FXV3, a novel cellulose-producing and stress resistant strain isolated from a fermented grape must. K. uvaceti FXV3 was able to grow under several stress conditions, including the presence of high concentrations of ethanol (up to 7.5 % v/v), a trait that is not observed in the model strain K. xylinus CECT 7351T. Moreover, K. uvaceti FXV3 produced increased concentrations of cellulose (4.31 mg/mL, 7 days after inoculation-DAI) when compared to K. xylinus CECT 7351T (1.42 mg/mL, 7 DAI). Moreover, the detailed analysis of strain FXV3 genome revealed the presence of several genes involved in cellulose and acetan biosynthesis, quorum-sensing and quenching mechanisms, carbohydrate, amino acid, alcohol and aldehyde metabolism, as well as several other genes involved in stress resistance. Additionally, comparative genomic analysis revealed the increased prevalence of stress resistance genes in K. uvaceti FXV3 when compared to K. xylinus CECT 7351T. Ultimately, this study reveals the increased biotechnological potential of K. uvaceti FXV3 and brings new insights into the genetics behind Komagataeibacter stress resistance and cellulose production abilities.

Abstract
Alcohol dehydrogenase 5 (ADH5) is a member of medium-chain dehydrogenase/reductase family and takes part in cellular formaldehyde and S-nitrosoglutathione metabolic network. 2-tridecanone (2-TD) is a toxic compound in many Solanaceae crops to defend against a variety of herbivory insects. In the broader context of insect development and pest control strategies, this study investigates how a new ADH5 from Helicoverpa armigera (HaADH5) regulates the expression of CYP6B6, a gene involved in molting and metamorphosis, in response to 2-TD treatment. Cloning of the HaADH5 complementary DNA sequence revealed that its 1002 bp open reading frame encodes 334 amino acids with a predicted molecular weight of 36.5 kD. HaADH5 protein was purified in the Escherichia coli Transetta (pET32a-HaADH5) strain using a prokaryotic expression system. The ability of HaADH5 protein to interact with the 2-TD responsive region within the promoter of CYP6B6 was confirmed by an in vitro electrophoretic mobility shift assay and transcription activity validation in yeast. Finally, the expression levels of both HaADH5 and CYP6B6 were found to be significantly decreased in the midgut of 6th instar larvae after 48 h of treatment with 10 mg/g 2-TD artificial diet. These results indicate that upon 2-TD treatment of cotton bollworm, HaADH5 regulates the expression of CYP6B6 by interacting with its promoter. As HaADH5 regulation of CYP6B6 expression may contribute to the larval xenobiotic detoxification, molting and metamorphosis, HaADH5 is a candidate target for controlling the growth and development of cotton bollworm.

Abstract
NAD(P)H-dependent enzymes are ideal biocatalysts for the industrial production of chiral compounds, such as chiral alcohols, chiral amino acids, and chiral amines; however, efficient strategies for the regeneration of coenzyme are expected as costly of the coenzymes. Herein, a solvent-tolerant isopropanol dehydrogenase (IDH) showing lower similarity (37%) with other proteins was obtained and characterized. The enzyme exhibits high catalysis ability of its substrates methanol, ethanol, ethylene glycol, glycerol, isopropanol, n-butanol, isobutanol, and acetone. And it has good adaptability in organic solvents (isopropanol, acetonitrile, acetone, and acetophenone). Interaction force and the corresponding amino acid residues between IDH and NAD+ or NADP+ were parsed by docking. The wide substrate spectrum, excellent organic solvent tolerance, and good biocatalytic activity make the excavated enzyme a promising biocatalyst for the production of chiral compounds industrially and the construction of coenzyme regeneration systems in aqueous organic phase or organic phase.

Abstract
Alcohol dehydrogenases belong to the large superfamily of medium-chain
dehydrogenases/reductases, which occur throughout the biological world and are
involved with many important metabolic routes. We considered the phylogeny of
190 ADH sequences of animals, fungi, and plants. Non-class III
Caenorhabditis elegans ADHs were seen closely related to
tetrameric fungal ADHs. ADH3 forms a sister group to amphibian, reptilian, avian
and mammalian non-class III ADHs. In fishes, two main forms are identified: ADH1
and ADH3, whereas in amphibians there is a new ADH form (ADH8). ADH2 is found in
Mammalia and Aves, and they formed a monophyletic group. Additionally, mammalian
ADH4 seems to result from an ADH1 duplication, while in Fungi, ADH formed
clusters based on types and genera. The plant ADH isoforms constitute a basal
clade in relation to ADHs from animals. We identified amino acid residues
responsible for functional divergence between ADH types in fungi, mammals, and
fishes. In mammals, these differences occur mainly between ADH1/ADH4 and
ADH3/ADH5, whereas functional divergence occurred in fungi between ADH1/ADH5,
ADH5/ADH4, and ADH5/ADH3. In fishes, the forms also seem to be functionally
divergent. The ADH family expansion exemplifies a neofunctionalization process
where reiterative duplication events are related to new activities.

Abstract
S-nitrosylation is a major redox posttranslational modification involved in cell signaling. The steady state concentration of S-nitrosylated proteins depends on the balance between the relative ability to generate nitric oxide (NO) via NO synthase and to reduce nitrosothiols by denitrosylases. Numerous works have been published in last decades regarding the role of NO and S-nitrosylation in the regulation of protein structure and function, and in driving cellular activities in vertebrates. Notwithstanding an increasing number of observations indicates that impairment of denitrosylation equally affects cellular homeostasis, there is still no report providing comprehensive knowledge on the impact that denitrosylation has on maintaining correct physiological processes and organ activities. Among denitrosylases, S-nitrosoglutathione reductase (GSNOR) represents the prototype enzyme to disclose how denitrosylation plays a crucial role in tuning NO-bioactivity and how much it deeply impacts on cell homeostasis and human patho-physiology. In this review we attempt to illustrate the history of GSNOR discovery and provide the evidence so far reported in support of GSNOR implications in development and human disease.

Abstract
Genome search of Bacillus subtilis revealed the presence of an open reading frame annotated as glutathione-dependent formaldehyde dehydrogenase/alcohol dehydrogenase. The open reading frame consists of 1137 nucleotides corresponding to a polypeptide of 378 amino acids. To examine whether the encoded protein is glutathione-dependent formaldehyde dehydrogenase or alcohol dehydrogenase, we cloned and characterized the gene product. Enzyme activity assays revealed that the enzyme exhibits a metal ion-dependent alcohol dehydrogenase activity but no glutathione-dependent formaldehyde dehydrogenase or aldehyde dismutase activity. Although the protein is of mesophilic origin, optimal temperature for the enzyme activity is 60°C. Thermostability analysis by circular dichroism spectroscopy revealed that the protein is stable up to 60°C. Presence or absence of metal ions in the reaction mixture did not affect the enzyme activity. However, metal ions were necessary at the time of protein production and folding. There was a marked difference in the enzyme activity and CD spectra of the proteins produced in the presence and absence of metal ions. The experimental results obtained in this study demonstrate that the enzyme is a bona-fide alcohol dehydrogenase and not a glutathione-dependent formaldehyde dehydrogenase.

Abstract
Acute heat stress perturbs cellular function on a variety of levels, leading to protein dysfunction and aggregation, oxidative stress and loss of metabolic homeostasis. If these challenges are not overcome quickly, the stressed organism can die. To better understand the earliest tissue-level responses to heat stress, we examined the proteomic response of gill from Geukensia demissa, an extremely eurythermal mussel from the temperate intertidal zone of eastern North America. We exposed 15°C-acclimated individuals to an acute near-lethal heat stress (45°C) for 1 h, and collected gill samples from 0 to 24 h of recovery. The changes in protein expression we found reveal a coordinated physiological response to acute heat stress: proteins associated with apoptotic processes were increased in abundance during the stress itself (i.e. at 0 h of recovery), while protein chaperones and foldases increased in abundance soon after (3 h). The greatest number of proteins changed abundance at 6 h; these included oxidative stress proteins and enzymes of energy metabolism. Proteins associated with the cytoskeleton and extracellular matrix also changed in abundance starting at 6 h, providing evidence of cell proliferation, migration and tissue remodeling. By 12 h, the response to acute heat stress was diminishing, with fewer stress and structural proteins changing in abundance. Finally, the proteins with altered abundances identified at 24 h suggest a return to the pre-stress anabolic state.

Abstract
During aerial exposure (emersion), most sessile intertidal invertebrates experience cellular stress caused by hypoxia, and the amount and types of hypoxia-induced stress will differ as exposure time increases, likely leading to altered metabolic responses. We examined proteomic responses to increasing emersion times and decreasing recovery (immersion) times in the mussel Geukensia demissa, which occurs in salt marshes along the east coast of North America. Individuals are found above mean tide level, and can be emersed for over 18 h during spring tides. We acclimated mussels to full immersion at 15°C for 4 weeks, and compared changes in gill protein expression between groups of mussels that were continually immersed (control), were emersed for 6 h and immersed during recovery for 18 h (6E/18R), were emersed for 12 h and recovered for 12 h (12E/12R), or were emersed for 18 h with a 6 h recovery (18E/6R). We found clear differences in protein expression patterns among the treatments. Proteins associated with anaerobic fermentation increased in abundance in 6E/18R but not in 12E/12R or 18E/6R. Increases in oxidative stress proteins were most apparent in 12E/12R, and in 18E/6R changes in cytoskeletal protein expression predominated. We conclude that G. demissa alters its strategy for coping with emersion stress over time, relying on anaerobic metabolism for short- to medium-duration exposure, but switching to an air-gaping strategy for long-term exposure, which reduces hypoxia stress but may cause structural damage to gill tissue.

Abstract
Alcohol, a drug widely abused, impacts the central nervous system functioning of diverse organisms. The behavioral responses to acute alcohol exposure are remarkably similar among humans and fruit flies. In its natural environment, rich in fermentation products, the fruit fly Drosophila melanogaster encounters relatively high levels of ethanol. The effects of ethanol and its metabolites on Drosophila have been studied for decades, as a model for adaptive evolution. Although extensive work has been done for elucidating patterns of genetic variation, substantially less is known about the genomic regions or genes that underlie the genetic variation of this important trait. To identify regions containing genes involved in the responses to ethanol, we used a mapping population of recombinant inbred (RIL) lines to map quantitative trait loci (QTL) that affect variation in resistance and recovery from ethanol sedation in adults and ethanol resistance in larvae. We mapped fourteen QTL affecting the response to ethanol on the three chromosomes. Seven of the QTL influence the resistance to ethanol in adults, two QTL are related to ethanol-coma recovery in adults and five affect the survival to ethanol in larvae. Most of the QTL were trait specific, suggesting that overlapping but generally unique genetic architectures underlie each trait. Each QTL explained up to 16.8% of the genetic variance among lines. Potential candidate loci contained within our QTL regions were identified and analyzed.

Abstract
Methanol is one of the most common short-chain alcohols in fermenting fruits, the natural food of the fruit fly, Drosophila melanogaster. The larvae cope continuously with methanol at various concentrations in order to survive and develop. In the present article, we found toxicities of dietary methanol and formaldehyde were enhanced by piperonyl butoxide, but not by 3-amino-1, 2, 4-triazole, 4-methylpyrazole, diethylmeleate, and triphenyl phosphate, when assessing by the combination index method. These results reveal that cytochrome P450 monooxygenases (CYPs), rather than catalases, alcohol dehydrogenases, glutathione S-transferases, and esterases, participate in methanol metabolism. Moreover, methanol exposure dramatically increased CYP activity. The ratios of the CYP activities in treated larvae to those in control reached, respectively, up to 3.0-, 3.9-, and 2.7-fold, at methanol concentrations of 22.6, 27.9, and 34.5 mg/g diet. In addition, methanol exposure greatly up-regulated the mRNA expression level of five Cyp genes, which were Cyp304a1, Cyp9f2, Cyp28a5, Cyp4d2, and Cyp4e2. Their resulting proteins were suggested as the candidate enzymes for methanol metabolism in D. melanogaster larvae.

Abstract
The structures, evolution and functions of alcohol dehydrogenase gene families and their products have been scrutinized for half a century. Our understanding of the enzyme structure and catalytic activity of plant alcohol dehydrogenase (ADH-P) is based on the vast amount of information available for its animal counterpart. The probable origins of the enzyme from a simple β-coil and eventual emergence from a glutathione-dependent formaldehyde dehydrogenase have been well described. There is compelling evidence that the small ADH gene families found in plants today are the survivors of multiple rounds of gene expansion and contraction. To the probable original function of their products in the terminal reaction of anaerobic fermentation have been added roles in yeast-like aerobic fermentation and the production of characteristic scents that act to attract animals that serve as pollinators or agents of seed dispersal and to protect against herbivores.

Abstract
N-acylethanolamines (NAEs) are members of the fatty acid amide family. The NAEs have been proposed to serve as metabolic precursors to N-acylglycines (NAGs). The sequential oxidation of the NAEs by an alcohol dehydrogenase and an aldehyde dehydrogenase would yield the N-acylglycinals and/or the NAGs. Alcohol dehydrogenase 3 (ADH3) is one enzyme that might catalyze this reaction. To define a potential role for ADH3 in NAE catabolism, we synthesized a set of NAEs and evaluated these as ADH3 substrates. NAEs were oxidized by ADH3, yielding the N-acylglycinals as the product. The (V/K)(app) values for the NAEs included here were low relative to cinnamyl alcohol. Our data show that the NAEs can serve as alcohol dehydrogenase substrates.

Abstract
Enzymes that synthesize retinoic acid (RA) constitute the first level of regulation of RA action. In vertebrates, enzymes of the medium-chain alcohol dehydrogenase (MDR-Adh) family catalyze the first step of the RA synthetic pathway by oxidizing retinol. Among MDR-Adh enzymes, Adh3 is the only member present in non-vertebrates, and whether Adh3 is actually involved in RA biosynthesis remains uncertain. Here, we investigate the MDR-Adh family in Oikopleura dioica, a urochordate representing the sister group to vertebrates. Oikopleura is of special interest because it has lost the classical RA role in development, which relaxed evolutionary constraints to preserve the RA-genetic machinery, leading to the loss of RA-system components. The hypothesis that Adh3 plays a role in RA synthesis predicts that the relaxation of selection in Oikopleura should have led to the loss of Adh3, or changes in residues related to retinol oxidation. The hypothesis also predicts changes in the expression pattern of Oikopleura Adh3 compared to other chordates that preserved RA-signaling. Our results, however, revealed the presence of a highly conserved Adh3 gene in Oikopleura, with no significant changes in functional residues. Our results also revealed that the Oikopleura Adh3 expression remains unchanged in comparison to other non-vertebrate chordates, restricted to specific compartments of the digestive system. Because Adh3 has been highly conserved in an animal that has dismantled the RA system, we conclude that Adh3 preservation is not due to a conserved role in RA synthesis. Thereby, if Adh3 plays a role in RA synthesis in vertebrates, it might be a lineage-specific neofunctionalization.

Abstract
When Phanerochaete chrysosporium is grown under oxygen-limited condition, ethanol is one of the important metabolites. In order to understand the metabolic mechanism of P. chrysosporium grown under oxygen-limited condition, a cDNA sequence (1 071 bp) designated "PCAdh1" encoding an alcohol dehydrogenase (ADH) was cloned from the filamentous white-rot fungus P. chrysosporium. PCAdh1 gene encodes a protein of 356 amino acid residues. Although the catalytic domain and coenzyme-binding domain were highly conserved, the protein sequence of PCAdh1 showed a low level of similarity to other known ADH. The recombinant PCAdh1 protein was expressed in Escherichia coli and its enzyme activity was detected. The protein was purified and used to prepare antibody. Semi-quantitative RT-PCR and Western blot demonstrated that the expression level of PCAdh1 in P. chrysosporium remained stable despite the lowered oxygen content, indicating that the gene expression is constitutive. But with the reduction of oxygen content, the overall activity of ADH from the crude mycelia proteins was increased during the growing periods, implying that the expression of other Adh genes in P. chrysosporium is inductive.

Abstract
Short-chain dehydrogenases/reductases (SDRs) constitute a large family of NAD(P)(H)-dependent oxidoreductases, sharing sequence motifs and displaying similar mechanisms. SDR enzymes have critical roles in lipid, amino acid, carbohydrate, cofactor, hormone and xenobiotic metabolism as well as in redox sensor mechanisms. Sequence identities are low, and the most conserved feature is an α/β folding pattern with a central beta sheet flanked by 2–3 α-helices from each side, thus a classical Rossmannfold motif for nucleotide binding. The conservation of this element and an active site, often with an Asn-Ser-Tyr-Lys tetrad, provides a platform for enzymatic activities encompassing several EC classes, including oxidoreductases, epimerases and lyases. The common mechanism is an underlying hydride and proton transfer involving the nicotinamide and typically an active site tyrosine residue, whereas substrate specificity is determined by a variable C-terminal segment. Relationships exist with bacterial haloalcohol dehalogenases, which lack cofactor binding but have the active site architecture, emphasizing the versatility of the basic fold in also generating hydride transfer-independent lyases. The conserved fold and nucleotide binding emphasize the role of SDRs as scaffolds for an NAD(P)(H) redox sensor system, of importance to control metabolic routes, transcription and signalling.

Abstract
The MDR superfamily with ~350-residue subunits contains the classical liver alcohol dehydrogenase (ADH), quinone reductase, leukotriene B4 dehydrogenase and many more forms. ADH is a dimeric zinc metalloprotein and occurs as five different classes in humans, resulting from gene duplications during vertebrate evolution, the first one traced to ~500 MYA (million years ago) from an ancestral formaldehyde dehydrogenase line. Like many duplications at that time, it correlates with enzymogenesis of new activities, contributing to conditions for emergence of vertebrate land life from osseous fish. The speed of changes correlates with function, as do differential evolutionary patterns in separate segments. Subsequent recognitions now define at least 40 human MDR members in the Uniprot database (corresponding to 25 genes when excluding close homologues), and in all species at least 10888 entries. Overall, variability is large, but like for many dehydrogenases, subdivided into constant and variable forms, corresponding to household and emerging enzyme activities, respectively. This review covers basic facts and describes eight large MDR families and nine smaller families. Combined, they have specific substrates in metabolic pathways, some with wide substrate specificity, and several with little known functions.

Abstract
Proteins play a pivotal role in thermophily. Comparing the molecular properties of homologous proteins from thermophilic and mesophilic bacteria is important for understanding the mechanisms of microbial adaptation to extreme environments. The thermophile Thermoanaerobacter (Thermoanaerobium) brockii and the mesophile Clostridium beijerinckii contain an NADP(H)-linked, zinc-containing secondary alcohol dehydrogenase (TBADH and CBADH) showing a similarly broad substrate range. The structural genes encoding the TBADH and the CBADH were cloned, sequenced, and highly expressed in Escherichia coli. The coding sequences of the TB adh and the CB adh genes are, respectively, 1056 and 1053 nucleotides long. The TB adh gene encoded an amino acid sequence identical to that of the purified TBADH. Alignment of the deduced amino acid sequences of the TB and CB adh genes showed a 76% identity and a 86% similarity, and the two genes had a similar preference for codons with A or T in the third position. Multiple sequence alignment of ADHs from different sources revealed that two (Cys-46 and His-67) of the three ligands for the catalytic Zn atom of the horse-liver ADH are preserved in TBADH and CBADH. Both the TBADH and CBADH were homotetramers. The substrate specificities and thermostabilities of the TBADH and CBADH expressed inE. coli were identical to those of the enzymes isolated from T. brockii and C. beijerinckii, respectively. A comparison of the amino acid composition of the two ADHs suggests that the presence of eight additional proline residues in TBADH than in CBADH and the exchange of hydrophilic and large hydrophobic residues in CBADH for the small hydrophobic amino acids Pro, Ala, and Val in TBADH might contribute to the higher thermostability of the T. brockii enzyme.

Abstract
We have determined that adipocytes are a major site of expression of the transcript for the novel alcohol dehydrogenase (ADH), Adhfe1. Adhfe1 is unique in that the sequence of its encoded protein places it among the iron-activated ADHs. Western blot analysis reveals Adhfe1 encodes a 50 kDa protein and immunocytochemical staining indicates mitochondrial localization. Adhfe1 transcript exhibits differentiation-dependent expression during in vitro brown and white adipogenesis. Unlike many adipocyte-enriched genes, however, Adhfe1 transcript expression in adipocytes is refractory to TNFalpha-mediated downregulation. However, use of pharmacological inhibitors reveals PI 3-kinase-mediated signals maintain the basal level of Adhfe1 transcript in 3T3-L1 adipocytes. Tissue profiling studies show Adhfe1 transcript is restricted to white and brown adipose tissues, liver, and kidney. In comparison to C57BL/6 mice, Adhfe1 transcript is downregulated 40% in white adipose tissue of ob/ob obese mice. Further characterization of Adhfe1 should yield new insights into adipocyte function and energy metabolism.

Abstract
The glycolytic proteins in plants are coded by small multigene families, which provide an interesting contrast to the high copy number of gene families studied to date. The alcohol dehydrogenase (Adh) genes encode glycolytic enzymes that have been characterized in some plant families. Although the amino acid sequences of zinc-containing long-chain ADHs are highly conserved, the metabolic function of this enzyme is variable. They also have different patterns of expression and are submitted to differences in nonsynonymous substitution rates between gene copies. It is possible that the Adh copies have been retained as a consequence of adaptative amino acid replacements which have conferred subtle changes in function. Phylogenetic analysis indicates that there have been a number of separate duplication events within angiosperms, and that genes labeled Adh1, Adh2 and Adh3 in different groups may not be homologous. Nonsynonymous/synonymous ratios yielded no signs of positive selection. However, the coefficients of functional divergence (theta) estimated between the Adh1 and Adh2 gene groups indicate statistically significant site-specific shift of evolutionary rates between them, as well as between those of different botanical families, suggesting that altered functional constraints may have taken place at some amino acid residues after their diversification. The theoretical three-dimensional structure of the alcohol dehydrogenase from Arabis blepharophylla was constructed and verified to be stereochemically valid.

Abstract
The alcohol dehydrogenase class 3 enzyme (ADH3) is the presumed ancestral form of the medium-chain dehydrogenase-reductase ADH family. This enzyme has been involved in formaldehyde and nitric oxide metabolism of a variety of deuterostomes and ecdysozoan protostomes. We have now characterized the structure and expression of the Adh3 gene in the lophotrochozoan Schmidtea mediterranea, a freshwater planarian. The planarian gene expands over 8.7 kb and is organized into 7 exons. The 1340 bp long Adh3cDNA contains a 1137 bp open reading frame corresponding to a deduced protein of 379 amino acids. The protein sequence is consistent with that expected for a typical class III enzyme. Twenty out of the twenty-two amino acid positions associated with enzymatic roles are strictly preserved, which suggests that the enzymatic capabilities have been conserved. In situ hybridization experiments show that Adh3 is expressed along the intestine of S. mediterranea specimens. This is consistent with the pattern observed in invertebrates and in contrast with the widespread expression of vertebrate Adh3. The comparative study across bilateria, which now includes a lophotrochozoan representative, further supports the idea that the urbilaterian Adh3 ancestor showed an intron-rich architecture and tissue-specific expression, and strengthens the view that widespread expression of Adh3 was a vertebrate innovation.

Abstract
Approximately 30 kb of genomic DNA enclosing the Adh locus from the medfly, Ceratitis capitata have been cloned and about 15 kb has been structurally and functionally characterized. The locus consists of two genes, Adh-1 and Adh-2, separated by an intergenic region, which is polymorphic in size ranging from approximately 6.4 kb to 8.1 kb. Both genes consist of three exons and two introns. The introns are below 200 bp in size, except the 1st intron of Adh-1, which is unexpectedly long, variable in size and contains a deleted mariner-like element (postdoc). The two genes are transcribed in different orientations. The Adh-2 gene shows the typical pattern of transcription seen in the homologous genes of Drosophilidae presenting high levels of expression in the fat body, gut and ovaries. The Adh-1 gene is only expressed in the body muscle tissues of embryos, larvae and adult flies, raising the question of what its biological function may be. A DNA fragment containing bases -102 to -1666 relative to the first base of the initiating ATG of Adh-1 is sufficient to drive the expression of a reporter gene in body muscles of Drosophila melanogaster embryos, larvae and adult flies. The study provides further insights into the evolution of the Adh genes of higher diptera.

Abstract
Nitric oxide (NO) is a signalling molecule involved in many physiological functions. An important via of NO action is through the S-nitrosylation of proteins, a post-translational modification that regulates the activity of enzymes, protein-protein interactions and signal transduction pathways. Alcohol dehydrogenase class III (ADH3) recognises S-nitrosoglutathione (GSNO), the main reservoir of non-protein S-nitrosothiol, and functions as an effective GSNO reductase (GSNOR) and as a safeguard against nitrosative stress. To investigate the evolutionary conservation of this metabolic role, we have produced recombinant Branchiostoma floridae ADH3. Pure preparations of ADH3 showed 2-fold higher activity as GSNOR than as formaldehyde dehydrogenase, the previously assumed main role for ADH3. To correlate ADH3 expression in the gut with areas of NO production, we analysed the tissue distribution of the nitric oxide synthase (NOS) enzyme in amphioxus larvae. Immunostaining of the NOS enzyme revealed expression in the gut and in the dorsal region of the club-shaped gland. Co-localization in the gut supports the ADH3 and NOS joint contribution to the NO/SNO homeostasis.

Abstract
Multiple members of the MDR-ADH (MDR: Medium-chain dehydrogenases/reductases; ADH: alcohol dehydrogenase) family are found in vertebrates, although the enzymes that belong to this family have also been isolated from bacteria, yeast, plant and animal sources. Initial understanding of the physiological roles and evolution of the family relied on biochemical studies, protein alignments and protein structure comparisons. Subsequently, studies at the genetic level yielded new information: the expression pattern, exon-intron distribution, in silico-derived protein sequences and murine knockout phenotypes. More recently, genomic and EST databases have revealed new family members and the chromosomal location and position in the cluster of both the first and new forms. The data now available provide a comprehensive scenario, from which a reliable picture of the evolutionary history of this family can be made.

Abstract
Ethanol is teratogenic to many vertebrates. We are utilizing zebrafish as a model system to determine whether there is an association between ethanol metabolism and ethanol-mediated developmental toxicity. Here we report the isolation and characterization of two cDNAs encoding zebrafish alcohol dehydrogenases (ADHs). Phylogenetic analysis of these zebrafish ADHs indicates that they share a common ancestor with mammalian class I, II, IV, and V ADHs. The genes encoding these zebrafish ADHs have been named Adh8a and Adh8b by the nomenclature committee. Both genes were genetically mapped to chromosome 13. The 1450-bp Adh8a is 82, 73, 72, and 72% similar at the amino acid level to the Baltic cod ADH8 (previously named ADH1), the human ADH1B2, the mouse ADH1, and the rat ADH1, respectively. Also, the 1484-bp Adh8b is 77, 68, 67, and 66% similar at the amino acid level to the Baltic cod ADH8, the human ADH1B2, the mouse ADH1, and the rat ADH1, respectively. ADH8A and ADH8B share 86% amino acid similarity. To characterize the functional properties of ADH8A and ADH8B, recombinant proteins were purified from SF-9 insect cells. Kinetic studies demonstrate that ADH8A metabolizes ethanol, with a V(max) of 13.4 nmol/min/mg protein, whereas ADH8B does not metabolize ethanol. The ADH8A K(m) for ethanol as a substrate is 0.7 mm. 4-Methyl pyrazole, a classical competitive inhibitor of class I ADH, failed to inhibit ADH8A. ADH8B has the capacity to efficiently biotransform longer chain primary alcohols (>/=5 carbons) and S-hydroxymethlyglutathione, whereas ADH8A does not efficiently metabolize these substrates. Finally, mRNA expression studies indicate that both ADH8A and ADH8B mRNA are expressed during early development and in the adult brain, fin, gill, heart, kidney, muscle, and liver. Together these results indicate that class I-like ADH is conserved in zebrafish, albeit with mixed functional properties.

Abstract
A novel ethanol-hypersensitive mutant, geko1 (gek1), was isolated from Arabidopsis thaliana. The gek1 mutant displays an enhanced sensitivity (10-100 times greater than the wild type) to ethanol in growth medium, while it grows normally in the absence of ethanol, and responds normally to other alcohols and to environmental stresses such as heat shock and high salinity. The ethanol-hypersensitive phenotype of gek1 requires alcohol dehydrogenase activity, indicating that gek1 is sensitive not to ethanol itself but to the metabolites of ethanol. Consistent with this, gek1 shows enhanced sensitivity to acetaldehyde in the medium. The endogenous acetaldehyde levels were not different between gek1-2 and wild-type seedlings treated with ethanol. These results indicate that the ethanol hypersensitivity of gek1 is due to an enhanced sensitivity to acetaldehyde toxicity, instead of abnormally elevated accumulation of toxic acetaldehyde, which has been thought to be the major cause of ethanol toxicity in mammal cells.

Abstract
The influence of starvation on activities of three enzymes (ADH, ODH and alpha GPDH) was studied in Drosophila melanogaster. The changes were compared in two inbred lines which had different allelic combinations at the Odh and Aldox loci. We also studied the effect of ethanol on media which contained no sucrose ("starvation conditions"). The results show that there are large differences in the larval and adult alcohol utilization. The alcohol content of the medium, in the absence of sugar, appeared to be toxic for the larvae, while the adults appeared to utilize it as an energy source. The two strains differed little in their responses to starvation or to the ethanol treatment applied under starvation conditions. We conclude that the degree of toxicity of ethanol is highly dependent on the presence of sucrose.

Abstract
Second instar larvae of Drosophila melanogaster were exposed to exogenous alcohol, which is known to influence the activities of several enzymes. In this study, the activity changes were followed in four enzymes (ADH, ODH, alpha GPDH and AOX) during ethanol exposure and compared in three inbred lines that had different allelic combinations at the Odh and Aldox loci. The results indicate that the Odh-Aldox region of the third chromosome may alter the general response to ethanol. The activity of ADH increased considerably in two strains in the larval stages in the presence of alcohol; nevertheless, strain 1, with the OdhS-AldoxF allelic combination, showed a delay in the ADH induction compared to strain 2, which had the OdhF-AldoxS combination. In strain 3 (OdhS*-AldoxS) larvae, ADH induction by environmental ethanol was not detected. Moreover, the activities of alpha GPDH and AOX in strains 2 and 3 were not affected by ethanol. In contrast, the activities of all four enzymes in strain 1 changed after exposure to ethanol.

Abstract
Mushroom alcohol dehydrogenase (ADH) from Agaricus bisporus (common mushroom, champignon) was purified to apparent homogeneity. One set of ADH isozymes was found, with specificity against formaldehyde/glutathione. It had two highly similar subunits arranged in a three-member isozyme set of dimers with indistinguishable activity. Determination of the primary structure by a combination of chemical, mass spectrometric and cDNA sequence analyses, correlated with molecular modeling towards human ADHs, showed that the active site residues are of class III ADH type, and that the subunit differences affect other residues. Class I and III forms of ADHs characterized define conserved substrate-binding residues (three and eight, respectively) useful for recognition of these enzymes in any organism.

Abstract
The purification and characterization of an organic solvent tolerant, NADH-dependent medium-chain secondary alcohol dehydrogenase (denoted sec-ADH "A") from Rhodococcus ruber DSM 44541 is reported. The enzyme can withstand elevated concentrations of organic solvents, such as acetone (up to 50% v/v) and 2-propanol (up to 80% v/v). Thus, it is ideally suited for the preparative-scale enantioselective oxidation of sec-alcohol and the asymmetric reduction of ketones, using acetone and 2-propanol, respectively, as cosubstrates for cofactor-regeneration via a coupled-substrate approach. The homodimeric protein was found to bear tightly bound zinc and displayed a molecular mass of 38 kDa per subunit as determined by SDS gel electrophoresis. The optimal temperature ranged from 30-50 degrees C and the half-life at 50 degrees C was 35 h. In addition, excellent storage stability was found. The pH optimum for reduction is pH 6.5; pH 9.0 is preferred for oxidation. The enzyme followed a sequential reaction mechanism. The substrates are medium chain sec-alcohols or (omega-1)-ketones; primary alcohols or aldehydes are not accepted.

Abstract
Human class III alcohol dehydrogenase (ADH3), also known as glutathione-dependent formaldehyde dehydrogenase, exhibited non-hyperbolic kinetics with ethanol at a near physiological pH 7.5. The S(0.5) and k(cat) were determined to be 3.4+/-0.3 M and 33+/-3 min(-1), and the Hill coefficient (h) 2.21+/-0.09, indicating positive cooperativity. Strikingly, the S(0.5) for ethanol was found to be 5.4 x 10(6)-fold higher than the K(m) for S-(hydroxymethyl)glutathione, a classic substrate for the enzyme, whereas the k(cat) for the former was 41% lower than that for the latter. Isotope effects on enzyme activity suggest that hydride transfer may be rate-limiting in the oxidation of ethanol. Kinetic simulations using the experimentally determined Hill constant suggest that gastric ADH3 may highly effectively contribute to the first-pass metabolism at 0.5-3 M ethanol, an attainable range in the gastric lumen during alcohol consumption. The positive cooperativity mainly accounts for this metabolic role of ADH3.

Abstract
Eukaryotic genomes code for at least eight medium-chain dehydrogenases/reductases (MDR) enzyme families of two types, with and without Zn(2+) at the active site. Four families have Zn(2+): 'Dimeric alcohol dehydrogenases (ADHs)' (including liver ADHs), 'Tetrameric ADHs' (including the yeast ADHs), 'Cinnamyl ADHs' and 'Polyol DHs'. In the human genome, there are minimally 23 MDR genes, but the list is still growing from further interpretations. Of these, seven genes on chromosome 4 (and three pseudogenes) represent the ADH classes in the gene order IV, Igamma, Ibeta, Ialpha, V, II and III. The lineages leading to human ADH establish five levels of divergence, with nodes at the MDR/short-chain dehydrogenases/reductases (SDR), dimer/tetramer, class III/non-III, further class, and intraclass levels of divergence. These multiplicities allow conclusions on pathways of function for ADHs and suggest this activity to have two roles in addition to its function in metabolism, one of a basic defence nature, the other of regulatory value in higher eukaryotes.

Abstract
The intestinal protozoan pathogen Entamoeba histolytica lacks mitochondria and derives energy from the fermentation of glucose to ethanol with pyruvate, acetyl enzyme Co-A, and acetaldehyde as intermediates. A key enzyme in this pathway may be the 97-kDa bifunctional E. histolytica alcohol dehydrogenase 2 (EhADH2), which possesses both alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase activity (ALDH). EhADH2 appears to be a fusion protein, with separate N-terminal ALDH and C-terminal ADH domains. Here, we demonstrate that EhADH2 expression is required for E. histolytica growth and survival. We find that a mutant EhADH2 enzyme containing the C-terminal 453 amino acids of EhADH2 has ADH activity but lacks ALDH activity. However, a mutant consisting of the N-terminal half of EhADH2 possessed no ADH or ALDH activity. Alteration of a single histidine to arginine in the putative active site of the ADH domain eliminates both ADH and ALDH activity, and this mutant EhADH2 can serve as a dominant negative, eliminating both ADH and ALDH activity when co-expressed with wild-type EhADH2 in Escherichia coli. These data indicate that EhADH2 enzyme is required for E. histolytica growth and survival and that the C-terminal ADH domain of the enzyme functions as a separate entity. However, ALDH activity requires residues in both the N- and C-terminal halves of the molecule.
