A cold shock-induced cyanobacterial RNA helicase. (1/485)

The ability to modify RNA secondary structure is crucial for numerous cellular processes. We have characterized two RNA helicase genes, crhB and crhC, which are differentially expressed in the cyanobacterium Anabaena sp. strain PCC 7120. crhC transcription is limited specifically to cold shock conditions while crhB is expressed under a variety of conditions, including enhanced expression in the cold. This implies that both RNA helicases are involved in the cold acclimation process in cyanobacteria; however, they presumably perform different roles in this adaptation. Although both CrhB and CrhC belong to the DEAD box subfamily of RNA helicases, CrhC encodes a novel RNA helicase, as the highly conserved SAT motif is modified to FAT. This alteration may affect CrhC function and its association with specific RNA targets and/or accessory proteins, interactions required for cold acclimation. Primer extension and analysis of the 5' untranslated region of crhC revealed the transcriptional start site, as well as a number of putative cold shock-responsive elements. The potential role(s) performed by RNA helicases in the acclimation of cyanobacteria to cold shock is discussed.  (+info)

Constitutive and nitrogen-regulated promoters of the petH gene encoding ferredoxin:NADP+ reductase in the heterocyst-forming cyanobacterium Anabaena sp. (2/485)

Determination of the putative transcription start points of the petH gene encoding ferredoxin:NADP+ reductase in the heterocyst-forming cyanobacteria Anabaena sp. PCC 7119 and PCC 7120 showed that this gene is transcribed from two promoters, one constitutively used under different conditions of nitrogen nutrition and the other one used in cells subjected to nitrogen stepdown and in nitrogen-fixing filaments. The latter promoter, whose use was NtcA-dependent but HetR-independent, was functional in heterocysts. The N-control transcriptional regulator NtcA was observed to bind in vitro to this promoter. For the sake of comparison, the transcription start points of the nifHDK operon in strain PCC 7120 and binding of NtcA to the nifHDK promoter were also examined.  (+info)

Quantitative structure activity relationships for the electron transfer reactions of Anabaena PCC 7119 ferredoxin-NADP+ oxidoreductase with nitrobenzene and nitrobenzimidazolone derivatives: mechanistic implications. (3/485)

The steady state single electron reduction of polynitroaromatics by ferredoxin-NADP+ oxidoreductase (EC 1.18.1.2) from cyanobacterium Anabaena PCC 7119 has been studied and quantitative structure activity relationships are described. The solubility of the polynitroaromatics as well as their reactivity towards ferredoxin-NADP+ oxidoreductase are markedly higher than those for previously studied mononitroaromatics and this enabled the independent measurement of the kinetic parameters-k(cat) and Km. Interestingly, the natural logarithm of the bimolecular rate constant, k(cat)/Km, and also the natural logarithm of k(cat) correlate with the calculated energy of the lowest unoccupied molecular orbital of the polynitroaromatic substrates. The minimal kinetic model in line with these quantitative structure activity relationships is a ping-pong mechanism which includes substrate binding equilibria in the second half reaction.  (+info)

Lag phase of CO2-dependent O2 evolution by illuminated Anabaena variabilis cells. (4/485)

The steady-state rate of CO2-dependent O2 evolution by Anabaena variabilis cells in response to illumination was established after a lag phase. The lag phase was shortened (1) in cells incubated with glucose as an oxidizable substrate and (2) upon an increase in light intensity. The lag phase was absent during electron transfer from H2O to p-benzoquinone (in combination with ferricyanide) involving Photosystem II. A lag was observed during electron transfer from H2O to methyl viologen involving Photosystems II and I, but not for electron transfer from N,N,N',N'-tetramethyl-p-phenylenediamine (in combination with ascorbate) to methyl viologen involving only Photosystem I. The lag phases of the light-induced H2O --> CO2 and H2O --> methyl viologen electron transfer reactions showed the same temperature dependences at 10-30 degrees C. The lag was prevented by 3-(3,4-dichlorophenyl)-1,1-dimethylurea at concentrations that caused partial inhibition of photosynthetic O2 evolution. Retardation of cell respiration by a combination of CN- and benzylhydroxamate shortened the lag phase of the H2O --> methyl viologen electron transfer. It is concluded that the lag phase is associated with the electron transfer step between Photosystem II and Photosystem I common for the photosynthetic and respiratory chains and is due to the stimulation of cell respiration during the initial period of illumination as a consequence of an increase in the reduced plastoquinone pool and to subsequent retardation of respiration resulting from the transition of the electron transfer chain to the competitive pathway involving Photosystem I.  (+info)

Electrostatic forces involved in orienting Anabaena ferredoxin during binding to Anabaena ferredoxin:NADP+ reductase: site-specific mutagenesis, transient kinetic measurements, and electrostatic surface potentials. (5/485)

Transient absorbance measurements following laser flash photolysis have been used to measure the rate constants for electron transfer (et) from reduced Anabaena ferredoxin (Fd) to wild-type and seven site-specific charge-reversal mutants of Anabaena ferredoxin:NADP+ reductase (FNR). These mutations have been designed to probe the importance of specific positively charged amino acid residues on the surface of the FNR molecule near the exposed edge of the FAD cofactor in the protein-protein interaction during et with Fd. The mutant proteins fall into two groups: overall, the K75E, R16E, and K72E mutants are most severely impaired in et, and the K138E, R264E, K290E, and K294E mutants are impaired to a lesser extent, although the degree of impairment varies with ionic strength. Binding constants for complex formation between the oxidized proteins and for the transient et complexes show that the severity of the alterations in et kinetics for the mutants correlate with decreased stabilities of the protein-protein complexes. Those mutated residues, which show the largest effects, are located in a region of the protein in which positive charge predominates, and charge reversals have large effects on the calculated local surface electrostatic potential. In contrast, K138, R264, K290, and K294 are located within or close to regions of intense negative potential, and therefore the introduction of additional negative charges have considerably smaller effects on the calculated surface potential. We attribute the relative changes in et kinetics and complex binding constants for these mutants to these characteristics of the surface charge distribution in FNR and conclude that the positively charged region of the FNR surface located in the vicinity of K75, R16, and K72 is especially important in the binding and orientation of Fd during electron transfer.  (+info)

Electron-nuclear double resonance and hyperfine sublevel correlation spectroscopic studies of flavodoxin mutants from Anabaena sp. PCC 7119. (6/485)

The influence of the amino acid residues surrounding the flavin ring in the flavodoxin of the cyanobacterium Anabaena PCC 7119 on the electron spin density distribution of the flavin semiquinone was examined in mutants of the key residues Trp(57) and Tyr(94) at the FMN binding site. Neutral semiquinone radicals of the proteins were obtained by photoreduction and examined by electron-nuclear double resonance (ENDOR) and hyperfine sublevel correlation (HYSCORE) spectroscopies. Significant differences in electron density distribution were observed in the flavodoxin mutants Trp(57) --> Ala and Tyr(94) --> Ala. The results indicate that the presence of a bulky residue (either aromatic or aliphatic) at position 57, as compared with an alanine, decreases the electron spin density in the nuclei of the benzene flavin ring, whereas an aromatic residue at position 94 increases the electron spin density at positions N(5) and C(6) of the flavin ring. The influence of the FMN ribityl and phosphate on the flavin semiquinone was determined by reconstituting apoflavodoxin samples with riboflavin and with lumiflavin. The coupling parameters of the different nuclei of the isoalloxazine group, as detected by ENDOR and HYSCORE, were very similar to those of the native flavodoxin. This indicates that the protein conformation around the flavin ring and the electron density distribution in the semiquinone form are not influenced by the phosphate and the ribityl of FMN.  (+info)

Identification of amino acids responsible for the oxygen sensitivity of ferredoxins from Anabaena variabilis using site-directed mutagenesis. (7/485)

The filamentous cyanobacterium Anabaena variabilis (ATCC 29413) possesses two molybdenum dependent nitrogenase systems, nif1 and nif2. The nif1 system is regulated by a developmental program involving heterocyst differentiation; the nif2 system is expressed in all cells only under anaerobic conditions and the expression is controlled environmentally. The genes fdxH1 and fdxH2, encoding two [2Fe-2S] ferredoxins, are part of the these two distinct and differently regulated nif gene clusters. The sensitivity of both ferredoxins to oxygen was different; the half-life of FdxH2 in air was only approximately 1.5 h, while FdxH1 retained 80% of its nitrogenase activity after 24 h. We used site-directed mutagenesis to identify the role of individual amino acid residues responsible for oxygen sensitivity and found out that the FdxH2 double mutant I76A/V77L was much more resistant to oxygen than the wild-type ferredoxin (FdxH2) and similar to FdxH1. By modelling it was shown that the accessibility of the cavity around the iron-sulfur cluster was responsible for that.  (+info)

The hetC gene is a direct target of the NtcA transcriptional regulator in cyanobacterial heterocyst development. (8/485)

The heterocyst is the site of nitrogen fixation in aerobically grown cultures of some filamentous cyanobacteria. Heterocyst development in Anabaena sp. strain PCC 7120 is dependent on the global nitrogen regulator NtcA and requires, among others, the products of the hetR and hetC genes. Expression of hetC, tested by RNA- DNA hybridization, was impaired in an ntcA mutant. A nitrogen-regulated, NtcA-dependent putative transcription start point was localized at nucleotide -571 with respect to the hetC translational start. Sequences upstream from this transcription start point exhibit the structure of the canonical cyanobacterial promoter activated by NtcA, and purified NtcA protein specifically bound to a DNA fragment containing this promoter. Activation of expression of hetC during heterocyst development appears thus to be directly operated by NtcA. NtcA-mediated activation of hetR expression was not impaired in a hetC mutant, indicating that HetC is not an NtcA-dependent element required for hetR induction.  (+info)

Expression and purification of the transcription factor NtcA from the cyanobacterium Anabaena PCC 7120Expression and purification of the transcription factor NtcA from the cyanobacterium Anabaena PCC 7120
Nitrogen is an essential building block of proteins and nucleic acids and, therefore, crucial for the biosphere. Nearly 79 % of the air consists of nitrogen, but in the form of nitrogen gas (N2), which cannot be utilized by most organisms. Nitrogen-fixing microorganisms such as cyanobacteria have a central role in supplying biologically useful nitrogen to the biosphere. Therefore, it is important to achieve further understanding of control mechanisms involved in nitrogen fixation and related processes. This thesis concerns different molecular aspects of the transcription factor NtcA from the heterocystous cyanobacterium Anabaena PCC 7120. Apart from performing oxygenic photosynthesis, Anabaena PCC 7120 is also capable of fixing nitrogen. NtcA is a protein regulating transcription of a wide range of genes and in particular genes involved in cyanobacterial global nitrogen control. NtcA binds as a dimer to the promoter regions of target genes such as those involved in nitrogen fixation and ...

Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that fixes N2 in specialized cells called heterocysts, which differentiate from vegetative cells in a process that requires the nitrogen control transcription factor NtcA. 2-Oxoglutarate-stimulated binding of purified NtcA to wild-type and modified versions of the ntcA gene promoter from Anabaena sp. was analyzed by mobility shift and DNase I footprinting assays, and the role of NtcA-binding sites in the expression of the ntcA gene during heterocyst differentiation was studied in vivo by using an ntcA-gfp translational fusion and primer extension analysis. Mutation of neither of the two identified NtcA-binding sites eliminated localized expression of ntcA in proheterocysts, but mutation of both sites led to very low, nonlocalized expression.

The CRP-family transcription factor NtcA, universally found in cyanobacteria, was initially discovered as a regulator operating N control. It responds to the N regime signaled by the internal 2-oxoglutarate levels, an indicator of the C to N balance of the cells. Canonical NtcA-activated promoters bear an NtcA-consensus binding site (GTAN8TAC) centered at about 41.5 nucleotides upstream from the transcription start point. In strains of the Anabaena/Nostoc genera NtcA is pivotal for the differentiation of heterocysts in response to N stress. In this study, we have used chromatin immunoprecipitation followed by high-throughput sequencing to identify the whole catalog of NtcA-binding sites in cells of the filamentous, heterocyst-forming cyanobacterium Anabaena sp. PCC 7120 three hours after the withdrawal of combined N. NtcA has been found to bind to 2,424 DNA regions in the genome of Anabaena, which have been ascribed to 2,153 genes. Interestingly, only a small proportion of those genes are involved in N

Anabaena sp. strain PCC 7120, a filamentous nitrogen-fixing cyanobacterium, is one of the research models for prokaryotic cell differentiation and pattern formation. Its specialized nitrogen-fixing cells, called heterocysts, are semiregularly distributed along filaments. In the process of differentiation from a vegetative cell to a heterocyst, cell division is stopped, an envelope consisting of outer polysaccharide layer and inner glycolipid layer is formed, photosynthetic oxygen production no longer takes place, and respiration is remarkably intensified (37). Due to the degradation of phycobilisomes, the phycobiliprotein fluorescence is basically missing in heterocysts (1).. Many genes involved in heterocyst differentiation have been identified. The master regulatory gene hetR (5) encodes a DNA-binding protein that probably recognizes the promoter regions of itself and other heterocyst differentiation genes (19). hetC encodes an ABC peptide or protein transporter (22), whose expression is ...

The goal of this research was to understand regulation of heterocyst differentiation in Anabaena sp. strain PCC 7120 (hereafter Anabaena PCC 7120) by characterizing regulatory genes for heterocyst formation and their mutants. Anabaena is a filamentous cyanobacterium that forms specialized cells for nitrogen fixation. called heterocysts, which differentiate from vegetative cells at intervals of 10 - 12 cells. Two genes, patS and hetN. are known to suppress the differentiation of vegetative cells into heterocysts for establishing and maintaining a pattern of heterocysts along the filament This study has established that PatS and HetN work independently to suppress differentiation. Using a patS-deletion strain with conditional expression of hetN, it was shown in this study that PatS and HetN are members of separate heterocyst suppression pathways. Inactivation of either of these negative regulators enhances heterocyst frequencies to >20%, compared to 9% in the wild type. However, inactivation of ...

Filamentous cyanobacteria represent model organisms for investigating multicellularity. For many species, nitrogen-fixing heterocysts are formed from photosynthetic vegetative cells under nitrogen limitation. Intracellular Ca2+ has been implicated in the highly regulated process of heterocyst differentiation but its role remains unclear. Ca2+ is known to operate more broadly in metabolic signalling in cyanobacteria, although the signalling mechanisms are virtually unknown. A Ca2+-binding protein called the Ca2+ Sensor EF-hand (CSE) is found almost exclusively in filamentous cyanobacteria. Expression of asr1131 encoding the CSE protein in Anabaena sp. PCC 7120 was strongly induced by low CO2 conditions, and rapidly downregulated during nitrogen step-down. A previous study suggests a role for CSE and Ca2+ in regulation of photosynthetic activity in response to changes in carbon and nitrogen availability. In the current study, a mutant Anabaena sp. PCC 7120 strain lacking asr1131 (Δcse) was highly prone

Anabaena sp. PCC 7120 (hereafter Anabaena) is a model cyanobacterium to study nitrogen fixation, cellular differentiation and several other key biological functions that are analogous in plants. As with any other organism, many genes in Anabaena encode an essential life function and hence cannot be deleted, causing a bottleneck in the elucidation of its genomic function. Antisense RNA (asRNA) mediated approach renders the study of essential genes possible by suppressing (but not completely eliminating) expression of the target gene, thus allowing them to function to some extent. Recently, we have successfully implemented this approach using the strong endogenous promoter of the psbA1 gene (D1 subunit of Photosystem II) introduced into a high-copy replicative plasmid (pAM1956) to suppress the transcript level of the target gene alr0277 (encoding a sigma factor, SigJ/Alr0277) in Anabaena.

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

Cyanobacteria are gram-negative prokaryotes that perform oxygenic photosynthesis by fixing carbon dioxide to produce oxygen. Multiple species, such as Anabaena sp. PCC 7120, of cyanobacteria are also capable of fixing N2 when nitrogen sources in the environment are scarce. Around 10% of the vegetative cells of the filamentous cyanobacteria Anabaena sp. PCC 7120 differentiate into heterocysts, cells that specialize in fixing nitrogen, in response to lack of nitrogen sources. Phycobilisomes are protein complexes composed of phycobiliproteins that catch sunlight to use in oxygenic photosynthesis and exist within the thylakoid membranes of vegetative cells. The phycobiliproteins absorb light and are composed of an α and β subunit. We removed the α and β subunit of phycocyanin, one of the phycobilproteins, to create iPC, a mutated strain of Anabaena.

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.

Heterocyst - WikipediaHeterocyst - Wikipedia
A notable symbiotic relationship is that of Anabaena cyanobacteria with Azolla plants. Anabaena reside on the stems and within leaves of Azolla plants[7]. The Azolla plant undergoes photosynthesis and provides fixed carbon for the Anabaena to use as an energy source for dinitrogenases in the heterocyst cells.[7]. In return, the heterocysts are able to provide the vegetative cells and the Azolla plant with fixed nitrogen in the form of ammonia which supports growth of both organisms[7][8].. This symbiotic relationship is exploited by humans in agriculture. In Asia, Azolla plants containing Anabaena species are used as biofertilizer where nitrogen is limiting[7] as well as in animal feed[8]. Different strains of Azolla-Anabaena are suited for different environments and may lead to differences in crop production[9]. Rice crops grown with Azolla-Anabaena as biofertilizer have been shown to result in a much greater quantity and quality of produce compared to crops without the cyanobacteria[8][10]. ...

Under nitrogen deprivation, filaments of the cyanobacterium Anabaena undergo a process of development, resulting in a one-dimensional pattern of nitrogen-fixing heterocysts separated by about ten photosynthetic vegetative cells. Many aspects of gene expression before nitrogen deprivation and during the developmental process remain to be elucidated. Furthermore, the coupling of gene expression fluctuations between cells along a multicellular filament is unknown. We studied the statistics of fluctuations of gene expression of HetR, a transcription factor essential for heterocyst differentiation, both under steady-state growth in nitrogen-rich conditions and at different times following nitrogen deprivation, using a chromosomally-encoded translational hetR-gfp fusion. Statistical analysis of fluorescence at the individual cell level in wild-type and mutant filaments demonstrates that expression fluctuations of hetR in nearby cells are coupled, with a characteristic spatial range of circa two to ...

I think I might do something on cell differentiation into heterocysts in the cyanobacteria, and look at cell fate. I read about something called patS which is a peptide that appears when the nitrogen levels of the area are very low and those bacterial cells that have large quantities of patS differentiate into heterocysts, which then secrete patS to the surrounding cells and inhibiting them from differentiating and this is how the reasonably equal spacing between heterocysts is achieved. Is this all correct? Also any more information on heterocyst formation would be appreciated ...

Impact of osmotic stress and temperature on pigments and proteins of Anabaenastrains
A study on Anabaena strains was carried out to investigate the effect of combined stress of polyethylene glycol 6000 (0,-5 bar and -7 bar) and temperature (30°C and 45 °C) on photosynthetic pigments (chlorophyll a, carotenoids, phycobilins) and total proteins as stress metabolites. The selected strains, A. oryzae and A. ellipsospora were sensitive to osmotic stress at ambient temperature of 30 0C and increase in the temperature to 45 0C was harmful to the growth of Anabaena strains. Chlorophyll a contents decreased at 30 0C and -7 bar pressure from 8.868 to 0.710 µg ml-1 and 4.360 to 0.220 µg ml-1 in A. oryzae and in A. ellipsospora, respectively and at -7 bar osmotic stress and 45 0C temperature, decrease in Chl a content of A.oryzae was 92.9%, however A. ellipsospora was highly sensitive and could not survive under these conditions. Carotenoids and phycobilins also showed decreasing trends with increase in temperature and osmotic potential. Moreover, combined stress adversely ...

BIFA: Sulphur Surcharge Will Be Extremely Unpopular | BalucoBIFA: Sulphur Surcharge Will Be Extremely Unpopular | Baluco
The British International Freight Association (BIFA) has slammed the recent introduction of the sulphur surcharge by the container shipping industry, describing it as unjustified.. To remind, the worlds largest liner company Maersk Line is planning to introduce a new fuel adjustment surcharge ahead of the 2020 sulphur cap. The surcharge will be introduced on January 1, 2019, and it will be levied separately from the companys freight rate.. As explained, the new Bunker Adjustment Factor (BAF) surcharge aims at recovering Maersk Lines costs of compliance with the global sulphur cap, which is set to increase the companys fuel bill by USD 2 billion a year.. Robert Keen, BIFA Director General, said rises of such magnitude were unjustified and could be construed as blatant profiteering by shipping lines determined to exploit the situation.. BIFA would prefer any necessary increases to be consolidated within freight rates and with any required fluctuation being managed against that figure.. BIFA ...

Growth and phage resistance of Anabaena sp. strain PCC 7120 in the presence of cyanophage AN-15. Mole,R., Meredith,D., Adams,D.G. (1997). Journal of Applied Phycology [J. Appl. Phycol. ] 9:339-345. The cyanophage AN-15 was found to have a requirement for either 1 mM calcium or 1 mM magnesium ions to maintain viral stability, whereas 1 mM calcium ions alone were essential for the infection process to proceed in Anabaena sp. strain PCC 7120. Following prolonged incubation, phage-resistant cells were detected at a high frequency (approximately 10 super(-5)) in lysates, as either renewed growth in liquid cultures, or as colonies in confluently lysed lawns. Southern hybridisation failed to detect AN-15 DNA in any of the resistant strains, implying that resistance is unlikely to be due to the presence of temperate phages. A high rate of spontaneous mutation is therefore likely to be the cause of resistance. Two classes of resistant cells were identified; those in which AN-15 failed to attach to host ...

The interactions can be divided into four classes: direct contacts to bases and phosphates, water-mediated and van der Waals contacts, and α-helix-dipole interactions. Because there is some asymmetry of interaction observed, we first describe the half of the complex where most of the interactions are provided by the A subunit and then indicate differences. Direct interactions with phosphate groups result in fastening DNA to protein with a specific register. These direct interactions link Lys76 with P−7/−8, Asn60 with P−8/−9/−10, amides of Leu61 and Arg62 with P−9/−10, Ser179 with P+3/+4 (Figs. 2 and 3), and amides of Glu180 and Ala181 with P+4/+5. From the opposite subunit, His69′ interacts with P+3/+4 (Figs. 2 and 3) and Arg74′ with P0/+1, and Arg188− forms a salt bridge with P−9/−10. Water-mediated interactions involve Arg34, His35, and Asp40 with P+2/+3 (with Asp40 approaching from the minor groove), and from the opposite subunit, Lys47′ and Arg74′ with P0/+1. ...

Ferredoxin-NAD reductase (FNR) catalyzes the electron transfer from ferredoxin to NAD via its flavin FAD cofactor. To get further insights in the architecture of the transient complexes produced during the hydride transfer event between the enzyme and the NAD coenzyme we have applied NMR spectroscopy using Saturation Transfer Difference (STD) techniques to analyze the interaction between FNRox and the oxidized state of its NAD coenzyme. We have found that STD NMR, together with the use of selected mutations on FNR and of the non-FNR reacting coenzyme analogue NA, are appropriate tools to provide further information about the the interaction epitope.. ...

The filamentous heterocyst-forming cyanobacterium Richelia intracellularis forms associations with diatoms and is very abundant in tropical and subtropical seas. The genus Richelia contains only one species, R. intracellularis Schmidt, although it forms associations with several diatom genera and has considerable variation in size and morphology. The genetic diversity, and possible host specificity, within the genus Richelia is unknown. Using primers against hetR, a gene unique for filamentous cyanobacteria, specific polymerase chain reaction (PCR) products were obtained from natural populations of R. intracellularis filaments associated with three diatom genera. Phylogenetic analyses of these sequences showed that they were all in the same clade. This clade contained only the R. intracellularis sequences. The genetic affiliation of hetR sequences of R. intracellularis to those of other heterocystous cyanobacteria strongly suggests that it was not closely related to endosymbiotic Nostoc spp, ...

A structural model of the DNA/RNA non-specific endonuclease NucA from Anabaena sp. PCC7120 that has been obtained on the basis of the three-dimensional structure of the related Serratia nuclease, suggests that the overall architecture of the active site including amino acid residues H124, N155 and E163 (corresponding to H89, N119 and E127 in Serratia nuclease) is similar in both nucleases. Substitution of these residues by alanine leads to a large reduction in activity (,0.1%), similarly as observed for Serratia nuclease demonstrating that both enzymes share a similar mechanism of catalysis with differences only in detail. NucA is inhibited by its specific polypeptide inhibitor with a K1 value in the subpicomolar range, while the related Serratia nuclease at nanomolar concentrations is only inhibited at an approximately 1000-fold molar excess of NuiA. The artificial chromophoric substrate deoxythymidine 3,5-bis-(p-nitrophenyl phosphate) is cleaved by NucA as well as by Serratia nuclease. ...

ChIP-seq Experiment and Data Analysis in the Cyanobacterium ...ChIP-seq Experiment and Data Analysis in the Cyanobacterium ...
Nitrogen is an essential nutrient for all living organisms. In cyanobacteria, a group of oxygenic photosynthetic bacteria, nitrogen homeostasis is maintained by an intricate regulatory network around the transcription factor NtcA. Although mechanisms controlling NtcA activity appear to be well understood, the sets of genes under its control (i.e., its regulon) remain poorly defined. In this protocol, we describe the procedure for chromatin immunoprecipitation using NtcA antibodies, followed by DNA sequencing analysis (ChIP-seq) during early acclimation to nitrogen starvation in the cyanobacterium Synechocystis sp. PCC 6803 (hereafter Synechocystis). This protocol can be extended to analyze any DNA-binding protein in cyanobacteria for which suitable antibodies exist.

Azolla plant surface. Coloured scanning electron micrograph (SEM) of the surface of an Azolla (water fern) plant. This plant has a symbiotic relationship with Anabaena cyanobacteria, where the cyanobacteria doubles the rate of photosynthesis and fulfils the nitrogen requirements of the plant. Both these factors give the water fern a competitive advantage over other water plants, a factor spotted by the Chinese 2000 years ago. The Anabaena-Azolla association is used as a green manure for rice crops. Anabaena is a filamentous organism, which, apart from vegetative cells, forms heterocysts and akinetes. - Stock Image C022/6173

Because of their simple requirements for rapid growth and ease of genetic manipulation as well as industrialized production, cyanobacteria are particularly attractive organisms for bioenergy production. One topic of research in my laboratory is focused on developing a suite of engineered Anabaena strains that are separately capable of directly converting CO2 and H2O into fuel ethanol, long-chain alcohols and other commodity chemicals using free solar energy.

Expression of toxin genes of high toxic Bacillus in cyanobacteria is a potenial way to reach prolonged mosquito control. But for their low toxicity, the genetically engineered cyanobacteria can not be practically used hitheto, and in most reports, the recombinant cells need lysate for toxicity essays. In. this research, high larvicidal activity of recombinant Anabaena was developed by expressing the toxin genes of B. sphaericus from an Anabaena promoter. LC_(50)(24h.) of the larvicidal cyanobacterium to larvae of Culex pipiens was 2.31×10~4 cells/ml, and its practical use under outdoor conditions was demonstrated. Similar to B. sphaericus, its toxicity to larvae of Culex pipiens. Anopheles sinensis and Aedes albopictus decrvases in order. For its simple growth requirements and wide ecological adaptations, the larvicidal Anabaena might become a new weapon for prolonged control on mosquito.

Engineered light controlled cell development for enhanced hydrogen production in Nostoc punctiforme ATCC 29133Engineered light controlled cell development for enhanced hydrogen production in Nostoc punctiforme ATCC 29133
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.. ...

General Information: Trichodesmium erythraeum strain IMS101 was isolated from the North Carolina coast in 1992 and grows in straight filaments. Filamentous marine cyanobacterium. This filamentous marine cyanobacterium is a nitrogen-fixing organism that contribues a significant amount of the global fixed nitrogen each year. These bacteria are unusual in that nitrogen fixation takes place in a differentiated cell called the diazocyte which is different from the nitrogen-fixing differentiated cell (heterocyst) found in other cyanobacteria. The diazocyte is developed in order to protect the oxygen-sensitive nitrogenases and includes a number of changes including production of more membranes and down-regulation of photosynthetic activity during times of peak nitrogen fixation (noontime). This organism gives the Red Sea its name when large blooms appear and is one of the organisms most often associated with large blooms in marine waters. ...
