The cDNA contains an open reading frame of 1038 base pairs which includes an amino acid sequence that matches the N-terminal 35 amino acid sequence of rabbit 3-hydroxyisobutyrate dehydrogenase at 33 residues. The cDNA predicts a 300-amino acid mature protein with an amino acid composition and molecular weight very similar to that of rabbit liver 3-hydroxyisobutyrate dehydrogenase. Northern blot ...
Four additional variants of alcohol and aldehyde dehydrogenases have been purified and functionally characterized, and their primary structures have been determined. The results allow conclusions about the structural and evolutionary relationships within the large family of MDR alcohol dehydrogenases from characterizations of the pigeon (Columba livia) and dogfish (Scyliorhinus canicula) major liver alcohol dehydrogenases. The pigeon enzyme turns out to be of class I type and the dogfish enzyme of class III type. This result gives a third type of evidence, based on purifications and enzyme characterization in lower vertebrates, that the classical liver alcohol dehydrogenase originated by a gene duplication early in the evolution of vertebrates. It is discernable as the major liver form at about the level in-between cartilaginous and osseous fish. The results also show early divergence within the avian orders. Structures were determined by Edman degradations, making it appropriate to acknowledge ...

Title: Effects of Trehalose on Pressure-Induced Inactivation of Yeast Alcohol Dehydrogenase. VOLUME: 12 ISSUE: 6. Author(s):Hyun Park, Gene Kidman and Dexter B. Northrop. Affiliation:Center for Drug Evaluation Division of Pharmaceutical Sciences, School of Pharmacy, University ofWisconsin-Madison, Madison, WI 53705, U.S.A.. Keywords:yeast alcohol dehydrogenase, trehalose, hydrostatic pressure, protein denaturation, barostability, thermostability, surface tension. Abstract: Isozymes of yeast alcohol dehydrogenase are slowly denatured at moderate hydrostatic pressures ( < 3 kbar). The time courses for inactivation are biphasic and both phases of both isozymes are protected by trehalose. ADH-I is slightly more barostable than ADH-II which is opposite to their thermostabilities. Trehalose at 1M extends their halflives about 6-fold at 2 kbar, pH 7.5 and 25°C. In contrast, 1M sucrose provides only 4.4-fold protection under identical conditions, a finding consistent with the superior protein ...

Guppy is a popular ornamental fish owing to its diverse body and fin coloration. More than 40 established color varieties have been selectively bred. The complementary DNAs for 2 enzymes that are involved in the de novo synthesis of pteridines and purines, which are important for the production of color pigments, were cloned from the caudal fin. Two cDNA isoforms for 6-pyruvoyl tetrahydropterin synthase (PTPS), with an open reading frame of 130 and 147 amino acids, respectively, were cloned from the Red Tail variety. The deduced amino acid sequence of the longer isoform shows an overall identity of about 65% to the mammalian PTPS sequences. The cDNA for xanthine dehydrogenase (XDH) was cloned from the Yellow Tail variety, and consists of an open reading frame of 1331 amino acids. Although it shows a higher overall identity to bovine aldehyde oxidase (AO; 54%) than to chicken XDH (51%), it has a NAD-binding domain that is specific to XDHs. Northern blot analysis indicated that both PTPS and XDH ...
An understanding protein structure is vital for the elucidation of its function. Information gleaned from the three dimensional structures of proteins is used to understand the biochemical and functional roles of such molecules in life and for the design and discovery of drug molecules for a variety of diseases and illnesses such as cancer, influenza and tuberculosis. The Protein Data Bank (PDB) is the central publicly accessible repository of all experimentally derived macromolecular structures. Containing over 80,000 structures of proteins and nucleic acids the PDB is an essential scientific resource. The PDB is managed by a consortium of international organizations collectively known as the worldwide Protein Data Bank (wwPDB). The Protein Data Bank in Europe (PDBe) is one of the founding members of the wwPDB along with the RCSB Protein Data Bank in the USA and Protein Data Bank Japan(PDBj) in Japan. In addition to serving as a deposition site for data deposited to the PDB, the PDBe also ...
In this work we characterize an alcohol dehydrogenase (ADH) from the hyperthermophilic archaeon Pyrobaculum aerophilum (PyAeADHII). We have previously found that PyAeADHII has no activity when standard ADH substrates are used but is active when α-tetralone is used as substrate. Here, to gain insights into enzyme function, we screened several chemical libraries for enzymatic modulators using an assay employing α-tetralone. The results indicate that PyAeADHII activity in the presence of α-tetralone was inhibited by compounds such as flunarizine. We also examined metal coordination of the enzyme in solution by performing metal substitution of the enzyme-bound zinc (Zn2+) with cobalt. The solution-based absorption spectra for cobalt substituted PyAeADHII supports substitution at the structural Zn2+ site. To gain structural insight, we obtained the crystal structure of both wild-type and cobalt-substituted PyAeADHII at 1.75 Å and 2.20 Å resolution, respectively. The X-ray data confirmed one ...

Nicotinamide phosphoribosyltransferase (NAMPT), also known as pre-B-cell colony-enhancing factor, is the rate-limiting enzyme that converts nicotinamide to nicotinamide mononucleotide (NMN) from nicotinamide in the salvage pathway of NAD+ biosynthesis in mammals. Nicotinamide mononucleotide adenylyltransferase 1 (NMNAT1) converts NMN to NAD+. The expression of NAMPT is upregulated during activation of immune cells such as monocytes, macrophages, dendritic cells, T and B cells, as well as in amniotic epithelial cells upon stimulation with several inflammatory cytokines. NAMPT-specific inhibitor, FK866 was found to deplete intracellular NAD content, resulting in apoptotic cell death in many cancer cell lines without any DNA damaging effect. Recently, Nakahata K et al, demonstrated that NAMPT is required to modulate circadian gene expression and circadian oscillation of NAD+.. ...
Previously we have developed a butanol tolerant mutant of Clostridium acetobutylicum Rh8, from the wild type strain DSM 1731. Strain Rh8 can tolerate up to 19 g/L butanol, with solvent titer improved accordingly, thus exhibiting industrial application potential. To test if strain Rh8 can be used for production of high level mixed alcohols, a single secondary alcohol dehydrogenase from Clostridium beijerinckii NRRL B593 was overexpressed in strain Rh8 under the control of thl promoter. The heterogenous gene sADH was functionally expressed in C. acetobutylicum Rh8. This simple, one-step engineering approach switched the traditional ABE (acetone-butanol-ethanol) fermentation to IBE (isopropanol-butanol-ethanol) fermentation. The total alcohol titer reached 23.88 g/l (7.6 g/l isopropanol, 15 g/l butanol, and 1.28 g/l ethanol) with a yield to glucose of 31.42%. The acid (butyrate and acetate) assimilation rate in isopropanol producing strain Rh8(psADH) was increased. The improved butanol tolerance and the

Title: A Research on Bioinformatics Prediction of Protein Subcellular Localization. VOLUME: 4 ISSUE: 3. Author(s):Gang Fang, Guirong Tao and Shemin Zhang. Affiliation:Department of Life Science, Xian University of Arts and Science, Xian 710065, China.. Keywords:Bioinformatics, prediction, protein subcellular localization, localizome, proteomics, database. Abstract: Protein subcellular localization is one of the key characteristic to understand its biological function. Proteins are transported to specific organelles and suborganelles after they are synthesized. They take part in cell activity and function efficiently when correctly localized. Inaccurate subcellular localization will have great impact on cellular function. Prediction of protein subcellular localization is one of the important areas in protein function research. Now it becomes the hot issue in bioinformatics. In this review paper, the recent progress on bioinformatics research of protein subcellular localization and its prospect ...
Protein structure prediction is an important problem in the post-genome era, which is one possible way to fill the gap between the rapid-growth sequences and the relative small number of proteins with experimentally determined structures. Despite the structural genomics initiatives and biochemical efforts, the cheapest and fastest way to obtain structural information is through prediction algorithms. Structure prediction, even in the absence of homology, is the first step of the sequence-structure-function paradigm. Great progress has been achieved in protein structure prediction during the last decades. The development of high-quality prediction methods has also been boosted by objective community-wide assessment experiments. However, the ultimate goal of protein structure prediction remains far away to reach. New algorithms, theory and advanced prediction techniques are necessary to facilitate the progress ...
Nicotinamide phosphoribosyltransferase (NAmPRTase or Nampt) also known as pre-B-cell colony-enhancing factor 1 (PBEF1) or visfatin is an enzyme that in humans is encoded by the NAMPT gene. This protein is the rate-limiting enzyme in the Nicotinamide adenine dinucleotide (NAD+) salvage pathway that converts nicotinamide to nicotinamide mononucleotide in mammals to enable NAD+ biosynthesis. NAMPT has also been reported to be a cytokine (PBEF) that promotes B cell maturation and inhibits neutrophil apoptosis. NAMPT is downregulated by an increase of miR-34a in obesity via a 3UTR functional binding site of NAMPT mRNA resulting in a reduction of NAD(+) and decreased SIRT1 activity. NAMPT catalyzes the following chemical reaction: nicotinamide + 5-phosphoribosyl-1-pyrophosphate (PRPP) ⇌ {\displaystyle \rightleftharpoons } nicotinamide mononucleotide (NMN) + pyrophosphate (PPi) Thus, the two substrates of this enzyme are nicotinamide and 5-phosphoribosyl-1-pyrophosphate (PRRP), whereas its two ...
TY - JOUR. T1 - Photogeneration of NADPH by oligothiophenes coupled with ferredoxin- NADP reductase. AU - Kim, Y.. AU - Ikebukuro, K.. AU - Muguruma, H.. AU - Karube, I.. PY - 1998/1/3. Y1 - 1998/1/3. N2 - The photogeneration of nicotinamide adenine dinucleotide hydrophosphate (NADPH) and its associated reaction were studied in a novel photo-energy conversion system. The system was composed of the oligothiophene, dimethyl- 4,4-bipyridinium (MV2+), EDTA, and combined with ferredoxin-NADP reductase (FDR, E.C.1.18.1.2). The NADPH was generated by the FDR catalysis via the reduction of MV2+ by the photocatalysis of oligothiophene and EDTA as the sacrificial electron donor. As a result, the rate of the NADPH generation depended on the concentrations of nicotinamide adenine dinucleotide phosphate (NADP+) and MV2+. The effect of the intension of applied light showed the same tendency. Rate values of photoreduction of MV2+ and photogeneration of NADPH systems were investigated as a function of the ...
Isocitrate dehydrogenases catalyze the oxidative decarboxylation of isocitrate to 2-oxoglutarate. These enzymes belong to two distinct subclasses, one of which utilizes NAD(+) as the electron acceptor and the other NADP(+). Five isocitrate dehydrogenases have been reported: three NAD(+)-dependent isocitrate dehydrogenases, which localize to the mitochondrial matrix, and two NADP(+)-dependent isocitrate dehydrogenases, one of which is mitochondrial and the other predominantly cytosolic. NAD(+)-dependent isocitrate dehydrogenases catalyze the allosterically regulated rate-limiting step of the tricarboxylic acid cycle. Each isozyme is a heterotetramer that is composed of two alpha subunits, one beta subunit, and one gamma subunit. The protein encoded by this gene is the gamma subunit of one isozyme of NAD(+)-dependent isocitrate dehydrogenase. This gene is a candidate gene for periventricular heterotopia. Several alternatively spliced transcript variants of this gene have been described, but only ...
The aerobic alkane conversion pathways for various lengths of alkanes from Gordonia sp. TF6 and Geobacillus thermodenitrificans were the basis for the alkane degradation parts. These pathways were implemented in E.coli using the BioBrick principle and characterized in detail with respect to single enzyme activities and affinity. Using these measurements the efficiency of different enzymes can easily be compared. We succesfully characterized the alkane hydroxylase system, which had an enzyme activity of 4.49x10-2 U/mg dry weight compared to 1.23x10-3 U/mg dry weight for the negative control. The enzyme activity of LadA was found to be 3.33x10-3U/mg total protein, compared to 5.49x10-4 U/mg total protein for the negative control strain. The characterization showed that the implemented alcohol dehydrogenase (ADH, for the conversion of long chain alkanols to alkanals) converted dodecanol 43% better than the standard E.coli. On the other hand, the expression of our ALDH system increased the dodecanal ...
In higher plants, genes for subunits of respiratory chain complex I (NADH:ubiquinone oxidoreductase) have so far been identified solely in organellar genomes. At least nine subunits are encoded by the mitochondrial DNA and 11 homologues by the plastid DNA. One of the key components of complex I is the subunit binding the substrate NADH. The corresponding gene for the mitochondrial subunit has now been cloned and identified in the nuclear genome from potato (Solanum tuberosum). The mature protein consists of 457 amino acids and is preceded by a mitochondrial targeting sequence of 30 amino acids. The protein is evolutionarily related to the NADH-binding subunits of complex I from other eukaryotes and is well conserved in the structural domains predicted for binding the substrate NADH, the FMN and one iron-sulphur cluster. Expression examined in different potato tissues by Northern blot analysis shows the highest steady-state mRNA levels in flowers. Precursor proteins translated in vitro from the ...
Candidate-gene-based association study which involves the identification of causative Single Nucleotide Polymorphisms (SNPs) for excellent traits has been proposed as a promising approach to dissect complex traits in forest trees. Hence, the goal of this study was to identify the genetic association among SNPs from Cinnamate 4-Hydroxylase (C4H) and Cinnamyl Alcohol Dehydrogenase (CAD) genes and an array of wood properties namely, specific gravity, wood density, fiber-length, cell wall thickness and microfibril angle from Acacia mangium Superbulk trees. Sequence variations within these two genes in 12 A. mangium Superbulk trees were examined and wood properties were measured. The data obtained was tested using General Linear Model (GLM) within TASSEL software. Two SNPs were identified in the exon of C4H, of which all the SNPs caused nonsynonymous mutations whereas five SNPs were identified in the CAD exons along with one deletion mutation. In addition, two SNPs were also identified in the CAD ...
In enzymology, a 6,7-dihydropteridine reductase (EC 1.5.1.34) is an enzyme that catalyzes the chemical reaction a 5,6,7,8-tetrahydropteridine + NAD(P)+ ⇌ {\displaystyle \rightleftharpoons } a 6,7-dihydropteridine + NAD(P)H + H+ The 3 substrates of this enzyme are 5,6,7,8-tetrahydropteridine, NAD+, and NADP+, whereas its 4 products are 6,7-dihydropteridine, NADH, NADPH, and H+. This enzyme participates in folate biosynthesis. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 5,6,7,8-tetrahydropteridine:NAD(P)+ oxidoreductase. Other names in common use include 6,7-dihydropteridine:NAD(P)H oxidoreductase, DHPR, NAD(P)H:6,7-dihydropteridine oxidoreductase, NADH-dihydropteridine reductase, NADPH-dihydropteridine reductase, NADPH-specific dihydropteridine reductase, dihydropteridine (reduced nicotinamide adenine dinucleotide), reductase, dihydropteridine reductase, ...

ADP-ribosyl cyclases catalyze the transformation of nicotinamide adenine dinucleotide (NAD+) into the calcium-mobilizing nucleotide second messenger cyclic adenosine diphosphoribose (cADP-ribose) by adenine N1-cyclization onto the C-1 position of NAD+. The invertebrate Aplysia californica ADP-ribosyl cyclase is unusual among this family of enzymes by acting exclusively as a cyclase, whereas the other members, such as CD38 and CD157, also act as NAD+ glycohydrolases, following a partitioning kinetic mechanism. To explore the intramolecular cyclization reaction, the novel nicotinamide 2-fluoroadenine dinucleotide (2-fluoro-NAD+) was designed as a sterically very close analogue to the natural substrate NAD+, with only an electronic perturbation at the critical N1 position of the adenine base designed to impede the cyclization reaction. 2-Fluoro-NAD+ was synthesized in high yield via Lewis acid catalyzed activation of the phosphoromorpholidate derivative of 2-fluoroadenosine 5-monophosphate and coupling

CombAlign is a new Python code that generates a gapped, multiple structure-based sequence alignment (MSSA) given a set of pairwise structure-based sequence alignments. CombAlign has utility in assisting the user in distinguishing structurally conserved versus divergent regions on a reference protein structure relative to other closely related structures. The method for combining multiple pairwise alignments is straightforward, involving the recording of pre-computed residue-residue correspondences between positions on the reference protein and each compared structure, and insertion of non-redundant gaps, as needed, to reflect amino-acid deletions or structural divergence in the reference relative to one or more compared structures.. CombAlign is not intended for use in applications for which greater benefit would be provided using a multiple structure alignment as generated by the vast majority of open-source programs [20], nor does it propose to address matters of protein evolution or function ...
Peptides are routinely identified from mass spectrometry-based proteomics experiments by matching observed spectra to peptides derived from protein databases. The error rates of these identifications can be estimated by target-decoy analysis, which involves matching spectra to shuffled or reversed peptides. Besides estimating error rates, decoy searches can be used by semi-supervised machine learning algorithms to increase the number of confidently identified peptides. As for all machine learning algorithms, however, the results must be validated to avoid issues such as overfitting or biased learning, which would produce unreliable peptide identifications. Here, we discuss how the target-decoy method is employed in machine learning for shotgun proteomics, focusing on how the results can be validated by cross-validation, a frequently used validation scheme in machine learning. We also use simulated data to demonstrate the proposed cross-validation schemes ability to detect overfitting.. ...

Low concentrations of hexachlorophene (HCP) inhibit a number of pyridine nucleotide-linked dehydrogenase enzymes. The I₅₀ HCP concentrations were 105 μM for pig heart isocitrate dehydrogenase (ICD), 65 μM for horse liver alcohol dehydrogenase, 39 μM for torula yeast glucose-6-phosphate dehydrogenase (G6PD), 6.0 μM for beef heart malate dehydrogenase, and 1.6 μM for bovine liver glutamate dehydrogenase (GDH) at the enzyme concentrations tested. HCP exhibited cooperative inhibition of these enzymes since the observed maximum interaction coefficient, n, between HCP binding sites ranged between 1.62 and 3.33 but it was not an allosteric effector as evidenced by Hill coefficients for the substrates of approximately 1.0 both in the absence and the presence of HCP. More detailed kinetic analysis showed that HCP in most cases exhibited mixed kinetics, giving average K[subscript i] values with G6PD of 16.6 μM for NADP⁺ and 18.2 μM for glucose -6- phosphate; with ICD of 171 µM for NADP⁺ ...
Dr. Roy Gravel, also a co-author of the study and member of the Alberta Childrens Hospital Research Institute says this study provides a tremendous opportunity to look at the prevention of diseases like spina bifida. "The work began as a study of a gene called Mtrr in mice. The goal was to shed light on how a mutation in Mtrr would affect folate metabolism. The multigeneral effect we observed was completely unexpected," says Gravel. The Mtrr gene encodes an enzyme that is key to the metabolism of folic acid and, when mutated, causes similar effects to dietary folic acid deficiency. The researchers found that when either the maternal grandmother or the maternal grandfather had this Mtrr mutation, their genetically normal grandchildren were at risk of a wide spectrum of developmental abnormalities, even if the mutated gene was not inherited through to the next generations. These developmental abnormalities were also seen in the fourth and fifth generations of mice. Through a series of ...

Vascular endothelial growth factor (VEGF) induces angiogenesis by stimulating endothelial cell proliferation and migration, primarily through the receptor tyrosine kinase VEGF receptor2 (Flk1/KDR). Reactive oxygen species (ROS) derived from NAD(P)H oxidase are critically important in many aspects of vascular cell regulation, and both the small GTPase Rac1 and gp91phox are critical components of the endothelial NAD(P)H oxidase complex. A role of NAD(P)H oxidase in VEGF-induced angiogenesis, however, has not been defined. In the present study, electron spin resonance spectroscopy is utilized to demonstrate that VEGF stimulates O2·− production, which is inhibited by the NAD(P)H oxidase inhibitor, diphenylene iodonium, as well as by overexpression of dominant-negative Rac1 (N17Rac1) and transfection of gp91phox antisense oligonucleotides in human umbilical vein endothelial cells (ECs). Antioxidants, including N-acetylcysteine (NAC), various NAD(P)H oxidase inhibitors, and N17Rac1 significantly ...
Humans metabolize ethanol primarily through NAD+-dependent alcohol dehydrogenase (ADH) class I enzymes (i.e. ADH1A, ADH1B, and ADH1C) to acetaldehyde and then metabolize acetaldehyde primarily by NAD2-dependent aldehyde dehydrogenase 2 (ALDH2) to acetic acid.[26][27] Eastern Asians reportedly have a deficiency in acetaldehyde metabolism in a surprisingly high percentage (approaching 50%) of their populations. The issue has been most thoroughly investigated in native Japanese where persons with a single-nucleotide polymorphism (SNP) variant allele of the ALDH2 gene were found; the variant allele, encodes lysine (lys) instead of glutamic acid (glu) at amino acid 487; this renders the enzyme essentially inactive in metabolizing acetaldehyde to acetic acid.[28][29] The variant allele is variously termed glu487lys, ALDH2*2, and ALDH2*504lys. In the overall Japanese population, about 57% of individuals are homozygous for the normal allele (sometimes termed ALDH2*1), 40% are heterozygous for glu487lys, ...

N2 - Methionine synthase [5-methyltetrahydrofolate-homocysteine S-methyltransferase (MTR)] is involved in folate-mediated one-carbon metabolism, a pathway known to play a role in colorectal carcinogenesis. We investigated whether the MTR D919G polymorphism was associated with risk of colorectal adenoma in a colonoseopy-based study of 513 cases and 609 controls from Minneapolis, MN. Adenoma risk appeared nonsignificantly increased among women with DG or GG genotype [adjusted odds ratio (OR) versus DD, 1.4; 95% confidence interval (CI), 0.9-2.1] but not men (OR, 1.0; 95% CI, 0.7-1.5). An interaction with methionine intake was observed among women, such that low versus high intake was associated with a 2.3-fold increased risk only among those with DG or GG genotype (95% CI, ...
The metabolic pathway of phenylpropanoids involves a number of enzymes. The shikimate pathway is a seven step metabolic route used by bacteria, fungi, and plants for the biosythesis of aromatic amino acids (phenylalanine, tyrosine, and tryptophan). In plants, the biosynthesis of all phenylpropanoids begins with the amino acids phenylalanine and tyrosine. Phenylalanine ammonia-lyase (PAL, a.k.a. phenylalanine/tyrosine ammonia-lyase) is an enzyme responsible for the transformation of L-phenylalanine or tyrosine into trans-cinnamic acid or p-coumaric acid respectively and ammonia. Trans-cinnamate 4-monooxygenase (cinnamate 4-hydroxylase) is the enzyme responsible for the transformation of trans-cinnamate into 4-hydroxycinnamate (p-coumaric acid). 4-Coumarate-CoA ligase is the enzyme responsible for the transformation of 4-coumarate (p-coumaric acid) into 4-coumaroyl-CoA. Cinnamyl-alcohol dehydrogenase (CAD), an enzyme responsible for the transformation of cinnamyl alcohol into cinnamaldehyde ...

TY - JOUR. T1 - Levels of retinoic acid and retinaldehyde dehydrogenase expression in eyes of the Mitf-vit mouse model of retinal degeneration.. AU - Duncan, T.. AU - Swint, C.. AU - Smith, S. B.. AU - Wiggert, B. N.. PY - 1999/6/28. Y1 - 1999/6/28. N2 - PURPOSE: Several reports have characterized the retinal degeneration observed in the Mitf(vit) mutant mouse. Despite these reports, the factor(s) that may cause or modulate the degeneration still are not well defined; however, it is known that the photoreceptors of Mitf(vit) mice die through an apoptotic mechanism. We reported previously that retinoid metabolism in the RPE of Mitf(vit)++ mice is perturbed. Retinoids regulate genes via the RAR and RXR nuclear receptor pathway that are involved in numerous cellular responses including apoptosis. It is possible that retinoic acid (RA) modulates the retinal degeneration observed in the Mitf(vit) mice. The purpose of this study was to evaluate the levels of RA in whole eyes, as well as its ...
Flavocytochrome b558 of the NADPH oxidase which generates superoxide in phagocytic cells, is a α1β1 heterodimer of gp91phox and p22phox, which together form a membrane-spanning electron-transport chain that transfers electrons from NADPH in the cytosol to oxygen. The C-terminal portion of gp91phox is a member of the ferredoxin-NADP+ reductase family of reductases. Little is known of the organization of the N-terminal section of this molecule, which is associated with the two haem structures. It is N-glycosylated, and site-directed mutagenesis has been used to eliminate the five potential N-linked glycosylation consensus sites. Mutated cDNAs were expressed in vitro. This approach provided evidence for glycosylation of residues Asn131, Asn148 and Asn239, but not of Asn96 and Asn429.. ...
Ferredoxin-NADP+-oxidoreductase (FNR) is a FAD-containg enzyme found both in the chloroplasts and non-photosynthetic plastids of higher plants. In chloroplasts, FNR has a well-defined role in linear electron flow, and in the root plastids, FNR is needed for nitrogen metabolism. In Arabidopsis thaliana, FNR is encoded by a gene family: At1g30510 and At4g05390 encode the root isozyme of FNR and At5g66190 and At1g20020 encode the leaf/chloroplast isozyme, which share a high degree of homology. Since FNR is a crucial determinant for the acclimation of the photosynthetic machinery, we have recently focused on resolving the specific physiological roles of the two distinct chloroplast-targeted FNR isoforms using the Arabidopsis fnr knock-out mutants (Lintala et al. 2007; 2009; 2012). We have also resolved the binding partner and the physiological significance of FNR shuttling within the chloroplast (Benz et al. 2009; 2010; Lintala et al.2014), and established differential drought stress -induced ...
Diflavin reductases are essential proteins capable of splitting the two-electron flux from reduced pyridine nucleotides to a variety of one electron acceptors. The primary sequence of diflavin reductases shows a conserved domain organization harboring two catalytic domains bound to the FAD and FMN flavins sandwiched by one or several non-catalytic domains. The catalytic domains are analogous to existing globular proteins: the FMN domain is analogous to flavodoxins while the FAD domain resembles ferredoxin reductases. The first structural determination of one member of the diflavin reductases family raised some questions about the architecture of the enzyme during catalysis: both FMN and FAD were in perfect position for interflavin transfers but the steric hindrance of the FAD domain rapidly prompted more complex hypotheses on the possible mechanisms for the electron transfer from FMN to external acceptors. Hypotheses of domain reorganization during catalysis in the context of the different members of

Although these woman were speaking the absolute truth, because it seemed impossible to believe, the disciples dismissed their report as idle tales - or literally, babbling that comes from a fevered and insane mind. As a result they spent longer in the darkness of despair than was necessary. Wise is the man who takes serious the babblings of the woman in his life - for therein often lies great truth that will shine light in his darkness.. Believing in the resurrection is an absolute essential doctrine. You do not believe in the true gospel if you reject the resurrection. If there is no resurrection, then Jesus did not rise from the dead. If Jesus did not rise from the dead, then death has power over Him and has defeated Him. If death has power over Jesus, He is not God. If Jesus is not God, He cannot offer a complete sacrifice for sins. If Jesus cannot offer a complete sacrifice for sins, my sins are not completely paid for before God. If my sins are not completely paid for before God, then I ...
