Respiratory terminal oxidases in the facultative chemoheterotrophic and dinitrogen fixing cyanobacterium Anabaena variabilis strain ATCC 29413: characterization of the cox2 locus. (1/21)

Upon nitrogen step-down, some filamentous cyanobacteria differentiate heterocysts, cells specialized for dinitrogen fixation, a highly oxygen sensitive process. Aerobic respiration is one of the mechanisms responsible for a microaerobic environment in heterocysts and respiratory terminal oxidases are the key enzymes of the respiratory chains. We used Anabaena variabilis strain ATCC 29413, because it is one of the few heterocyst-forming facultatively chemoheterotrophic cyanobacteria amenable to genetic manipulation. Using PCR with degenerate primers, we found four gene loci for respiratory terminal oxidases, three of which code for putative cytochrome c oxidases and one whose genes are homologous to cytochrome bd-type quinol oxidases. One cytochrome c oxidase, Cox2, was the only enzyme whose expression, tested by RT-PCR, was evidently up-regulated in diazotrophy, and therefore cloned, sequenced, and characterized. Up-regulation of Cox2 was corroborated by Northern and primer extension analyses. Strains were constructed lacking Cox1 (a previously characterized cytochrome c oxidase), Cox2, or both, which all grew diazotrophically. In vitro cytochrome c oxidase and respiratory activities were determined in all strains, allowing for the first time to estimate the relative contributions to total respiration of the different respiratory electron transport branches under different external conditions. Especially adding fructose to the growth medium led to a dramatic enhancement of in vitro cytochrome c oxidation and in vivo respiratory activity without significantly influencing gene expression.  (+info)

High-affinity vanadate transport system in the cyanobacterium Anabaena variabilis ATCC 29413. (2/21)

High-affinity vanadate transport systems have not heretofore been identified in any organism. Anabaena variabilis, which can fix nitrogen by using an alternative V-dependent nitrogenase, transported vanadate well. The concentration of vanadate giving half-maximum V-nitrogenase activity when added to V-starved cells was about 3 x 10(-9) M. The genes for an ABC-type vanadate transport system, vupABC, were found in A. variabilis about 5 kb from the major cluster of genes encoding the V-nitrogenase, and like those genes, the vupABC genes were repressed by molybdate; however, unlike the V-nitrogenase genes the vanadate transport genes were expressed in vegetative cells. A vupB mutant failed to grow by using V-nitrogenase unless high levels of vanadate were provided, suggesting that there was also a low-affinity vanadate transport system that functioned in the vupB mutant. The vupABC genes belong to a family of putative metal transport genes that include only one other characterized transport system, the tungstate transport genes of Eubacterium acidaminophilum. Similar genes are not present in the complete genomes of other bacterial strains that have a V-nitrogenase, including Azotobacter vinelandii, Rhodopseudomonas palustris, and Methanosarcina barkeri.  (+info)

Cross-functionality of nitrogenase components NifH1 and VnfH in Anabaena variabilis. (3/21)

Anabaena variabilis fixes nitrogen under aerobic growth conditions in differentiated cells called heterocysts using either a Mo nitrogenase or a V nitrogenase. The nifH1 gene, which encodes the dinitrogenase reductase of the Mo nitrogenase that is expressed only in heterocysts, is cotranscribed with nifD1 and nifK1, which together encode the Mo dinitrogenase. These genes were expressed in the presence or absence of molybdate or vanadate. The vnfH gene, which encodes the dinitrogenase reductase of the V nitrogenase, was located about 23 kb from vnfDGK, which encodes the V dinitrogenase; however, like vnfDGK, vnfH was expressed only in the absence of molybdate, with or without vanadate. Like nifH1, the vnfH gene was expressed exclusively in heterocysts under either aerobic or anaerobic growth conditions and thus is under the control of developmental factors. The vnfH mutant was able to grow diazotrophically using the V nitrogenase, because NifH1, which was also made in cells starved for molybdate, could substitute for VnfH. Under oxic conditions, the nifH1 mutant grew in the absence of molybdate but not in its presence, using VnfH, while the nifH1 vnfH double mutant did not grow diazotrophically with or without molybdate or vanadate. A nifH1 mutant that expressed nifDK and vnfH but not vnfDGK was able to grow and fix nitrogen normally, indicating that VnfH could substitute for NifH in the Mo nitrogenase and that these dinitrogenase reductases are not involved in determining the metal specificity of the Mo nitrogenase or the V nitrogenase.  (+info)

Discovery of two cyanobacterial phenylalanine ammonia lyases: kinetic and structural characterization. (4/21)

Phenylalanine ammonia lyase (PAL) catalyzes the deamination of phenylalanine to cinnamate and ammonia. While PALs are common in terrestrial plants where they catalyze the first committed step in the formation of phenylpropanoids, only a few prokaryotic PALs have been identified to date. Here we describe for the first time PALs from cyanobacteria, in particular, Anabaena variabilis ATCC 29413 and Nostoc punctiforme ATCC 29133, identified by screening the genome sequences of these organisms for members of the aromatic amino acid ammonia lyase family. Both PAL genes associate with secondary metabolite biosynthetic gene clusters as observed for other eubacterial PAL genes. In comparison to eukaryotic homologues, the cyanobacterial PALs are 20% smaller in size but share similar substrate selectivity and kinetic activity toward L-phenylalanine over L-tyrosine. Structure elucidation by protein X-ray crystallography confirmed that the two cyanobacterial PALs are similar in tertiary and quatenary structure to plant and yeast PALs as well as the mechanistically related histidine ammonia lyases.  (+info)

High cell density culture of Anabaena variabilis with controlled light intensity and nutrient supply. (7/21)

Controlling the light energy and major nutrients is important for high cell density culture of cyanobacterial cells. The growth phase of Anabaena variabilis can be divided into an exponential growth phase and a deceleration phase. In this study, the cell growth in the deceleration phase showed a linear growth pattern. Both the period of the exponential growth phase and the average cell growth rate in the deceleration phase increased by controlling the light intensity. To control the light intensity, the specific irradiation rate was maintained above 10 micromol/s/g dry cell by increasing the incident light intensity stepwise. The final cell density increased by controlling the nutrient supply. For the control of the nutrient supply, nitrate, phosphate, and sulfate were intermittently added based on the growth yield, along with the combined control of light intensity and nutrient concentration. Under these control conditions, both final cell concentration and cell productivity increased, to 8.2 g/l and 1.9 g/l/day, respectively.  (+info)

The aim of this thesis is to enhance heterocyst-based hydrogen production inNostoc punctiforme ATCC 29133. We envision to do so by finely regulatingthe ratio of heterocyst in order to optimize the filament energy balance. Wehereby report the development of an optogenetic synthetic switch basedon the native PcpeC promoter. The optogenetic switch featured a 24-folddynamic range when measuring reporter sfGFP fluorescence. Such a geneticgate was conceived to artificially drive the expression of hetR, the masterregulator of heterocyst development. We achieved to induce enhancedheterocyst differentiation in the presence of ammonia only by changing thechromatic properties of the light source. Thus, the natural cell developmentregulation was substituted by effectively introducing a full person-drivencontrol over the process.. ...
The suite of biological catalysts found in Nature has the potential to contribute immensely to scientific advancements, ranging from industrial biotechnology to innovations in bioenergy and medical intervention. The endeavour to obtain a catalyst of choice is, however, wrought with challenges. Herein we report the design of a structure-based annotation system for the identification of functionally similar enzymes from diverse sequence backgrounds. Focusing on an enzymatic activity with demonstrated synthetic and therapeutic relevance, five new phenylalanine ammonia lyase (PAL) enzymes were discovered and characterised with respect to their potential applications. The variation and novelty of various desirable traits seen in these previously uncharacterised enzymes demonstrates the importance of effective sequence annotation in unlocking the potential diversity that Nature provides in the search for tailored biological tools. This new method has commercial relevance as a strategy for assaying the ...

Quercus variabilis is a tree species of ecological and economic value that is widely distributed in China. To effectively evaluate, use, and conserve resources, we applied 25 pairs of simple sequence repeat (SSR) primers to study its genetic diversity and genetic structure in 19 natural forest or natural secondary forest populations of Q. variabilis (a total of 879 samples). A total of 277 alleles were detected. Overall, the average expected heterozygosity (He) was 0.707 and average allelic richness (AR) was 7.79. Q. variabilis manifested a loss of heterozygosity, and the mean of inbreeding coefficient (FIS) was 0.044. Less differentiation among populations was observed, and the genetic differentiation coefficient (FST) was 0.063. Bayesian clustering analysis indicated that the 19 studied populations could be divided into three groups based on their genetic makeup, namely, the Southwest group, Central group, and Northeastern group. The Central group, compared to the populations of the Southwest and

Phenylalanine ammonia lyase (EC 4.3.1.24) is an enzyme that catalyzes a reaction converting L-phenylalanine to ammonia and trans-cinnamic acid. Phenylalanine ammonia lyase (PAL) is the first and committed step in the phenyl propanoid pathway and is therefore involved in the biosynthesis of the polyphenol compounds such as flavonoids, phenylpropanoids, and lignin in plants. Phenylalanine ammonia lyase is found widely in plants, as well as some yeast and fungi, with isoenzymes existing within many different species. It has a molecular mass in the range of 270-330 kDa. The activity of PAL is induced dramatically in response to various stimuli such as tissue wounding, pathogenic attack, light, low temperatures, and hormones. PAL has recently been studied for possible therapeutic benefits in humans afflicted with phenylketonuria. It has also been used in the generation of L-phenylalanine as precursor of the sweetener aspartame. The enzyme is a member of the ammonia lyase family, which cleaves ...
Findings: Functional categorization of expressed transcripts revealed the conservation of genes involved in various biological processes like responses to chemical (12.7%), responses to abiotic stimulus (11.8%), biosynthesis processes (11.8%), and cellular metabolic processes (10.4%) in grape berries exposed to high temperature. The major up-regulated genes included isocitratelyase, cysteine proteinases superfamily protein, cupin family protein, and glycosyl hydrolase genes, and the major down-regulated genes included flavanone 3-hydroxylase, phenylalanine ammonia lyase, chlorophyll A-B binding family protein, and polygalacturonase inhibiting protein genes in grape berries exposed to high temperature.

The roots of cassava present high postharvest perishability due to physiological deterioration that develops in wounded tissues usaully within two to three days after harvest at room temperature. The physiological deterioration is characterized by the appearance of blue-black streaks in the root vascular tissue and storage parenchyma, which progresses through the whole length of the root, being the initial cause for the poor acceptability for fresh consumption. This darkening is attributed to reactions involving the enzymes phenylalanine ammonia lyase, polyphenol oxidase and peroxidase. The objective of this work was to evaluate the effects biochemical, physiological and physical phases by the called minimal processing, the use of antioxidants and of packaging on the development of physiological deterioration in cassava roots during a period of preservation, in order to extend the shelf-life of the product, as well as to ensure food safety during the commercialization, distribution and ...

Coloured scanning electron micrograph (SEM) of Anabaena sp., Gram-negative, oxygenic, photosynthetic, nitrogen fixing, filamentous cyanobacterium (prokaryote). Note the larger cells in the filament called heterocysts which are involved in nitrogen fixation. Anabaena is a genus of filamentous cyanobacteria (formerly known as blue, Green algae). It found as planktonic cyanobacterium (all types of water) and is known for its nitrogen fixing abilities. Blooms or massive growths can occur in waters with a lot of nutrients. These blooms discolour the water and give it a bad odour when the cells die and decay. Anabaena is one of four genera of cyanobacteria that produce neurotoxins. These toxins are harmful to local wildlife, as well as farm animals and pets. Production of these neurotoxins is part of its symbiotic relationships it forms with certain plants. Some species of Anabaena are endophytes. Magnification: x660 when shortest axis printed at 25 - Stock Image C032/2525

Phenylketonuria Phenylketonuria (PKU) is a rare condition in which a baby is born without the ability to properly break down an amino acid called phenylalanine. Causes, incidence, and risk factors Phenylketonuria (PKU) is inherited, which means it is passed down through families. Both parents must pass on the defective gene in order for a baby…

Geosmin has often been associated with off-flavor problems in drinking water with *Anabaena* sp. as the major producer. Rapid on-site detection of geosmin-producers as well as geosmin is important for a timely management response to potential off-flavor events. In this study, quantitative polymerase chain reaction (qPCR) methods were developed to detect the levels of *Anabaena* sp. and geosmin, respectively, by designing two PCR primer sets to quantify the *rpoC₁* gene (ARG) and geosmin synthase one (GSG) in *Anabaena* sp. in freshwater systems. The ARG density determined by qPCR assay is highly related to microscopic cell count (r² = 0.726, p | 0.001), and the limit of detection (LOD) and limit of quantification (LOQ) of the qPCR method were 0.02 pg and 0.2 pg of DNA, respectively. At the same time, the relationship between geosmin concentrations measured by gas chromatography-mass spectrometry (GC-MS) and GSG copies was also established (r² = 0.742, p | 0.001) with similar LOD and LOQ values.

Alkaahan se olla aika pitkälti kaikille selvää että WWE on näinä päivinä enemmälti puuduttava, tylsä ja pahimmillaan itseään toistava. Mutta aina kun edetään kohti seuraavaa Wrestlemaniaa, jotenkin he osaavat vain ottaa niskastaan kiinni ja kohottaa pari feudia sen verran korkealle että sitä alkaa taas odottamaan vesikielellä. Tämän viikon Rawssa oli tämä Shawn Michaelsin ja Undertakerin promo-paketti joka oli parasta antia mitä WWE on tuottanut pitkään aikaan.
