The Salmonella typhi melittin resistance gene pqaB affects intracellular growth in PMA-differentiated U937 cells, polymyxin B resistance and lipopolysaccharide. (1/706)

Salmonella typhi is the causative agent of typhoid fever in humans. A cell-culture based assay involving the human monocyte macrophage cell line U937 has been developed to examine S. typhi invasion and survival. An S. typhi PhoP- (null) mutant was shown to be restricted in net growth in phorbol myristate acetate (PMA) differentiated U937 (PMA-U937) cells, and an S. typhi PhoPc (constitutive) mutant showed a defect in invasion. Neither of the phoP/Q mutants were growth impaired in HeLa cells, however the PhoPc mutant was impaired in invasion. As opposed to what was found for S. typhi, Salmonella typhimurium wild-type, PhoP- and PhoPc mutants grew equally well in PMA-U937 cells, indicating that the PhoP(-)-mediated net growth restriction in the PMA-U937 cells was S. typhi specific. An S. typhi mutation, pqaB::MudJ, recently shown to be a PhoP-activated locus, was shown to have a net growth defect in PMA-U937 cells. Sequencing of the S. typhipqaB gene revealed it had 98% identity to the fifth gene in a S. typhimurium PmrA/B regulated operon necessary for 4-aminoarabinose lipid A modification and polymyxin B resistance. The pqaB locus was regulated by PmrA/B (whose activity is modulated by PhoP-PhoQ) and the pqaB transposon mutant was sensitive to polymyxin B. The lipopolysaccharides (LPS) of S. typhi and S. typhimurium wild-type, PhoP- and PhoPc mutants, were compared by SDS-PAGE and silver staining. Differences in the LPS profile between the two Salmonella species were observed, and shown to be affected differently by the PhoPc mutation. Additionally, the pqaB::MudJ mutation affected S. typhi LPS. The effects on LPS may have ramifications for the difference between S. typhi and S. typhimurium infection of hosts.  (+info)

Effect of 9-beta-D-arabinofuranosyladenine 5'-monophosphate and 9-beta-D-arabinofuranosylhypoxanthine 5'-monophosphate on experimental herpes simplex keratitis. (2/706)

Treatment of established experimental keratitis caused by herpes simplex virus with 9-beta-d-arabinofuranosyladenine 5'-monophosphate (Ara-AMP) or 9-beta-d-arabinofuranosylhypoxanthine 5'-monophosphate (Ara-HxMP) showed that the Ara-AMP, in a concentration of 2 or 20%, had a significant effect on the keratitis but that 0.4% Ara-HxMP showed only minimal activity. Ara-AMP was also effective in the treatment of idoxuridine-resistant keratitis. No local toxicity with a high concentration (20%) of Ara-AMP was seen, but the duration of therapy was brief.  (+info)

Transcriptional activation of ydeA, which encodes a member of the major facilitator superfamily, interferes with arabinose accumulation and induction of the Escherichia coli arabinose PBAD promoter. (3/706)

Induction of genes expressed from the arabinose PBAD promoter is very rapid and maximal at low arabinose concentrations. We describe here two mutations that interfere with the expression of genes cloned under arabinose control. Both mutations map to the ydeA promoter and stimulate ydeA transcription; overexpression of YdeA from a multicopy plasmid confers the same phenotype. One mutation is a large deletion that creates a more efficient -35 region (ATCACA changed to TTCACA), whereas the other affects the initiation site (TTTT changed to TGTT). The ydeA gene is expressed at extremely low levels in exponentially growing wild-type cells and is not induced by arabinose. Disruption of ydeA has no detectable effect on cell growth. Thus, ydeA appears to be nonessential under usual laboratory growth conditions. The ydeA gene encodes a membrane protein with 12 putative transmembrane segments. YdeA belongs to the largest family of bacterial secondary active transporters, the major facilitator superfamily, which includes antibiotic resistance exporters, Lac permease, and the nonessential AraJ protein. Intracellular accumulation of arabinose is strongly decreased in mutant strains overexpressing YdeA, suggesting that YdeA facilitates arabinose export. Consistent with this interpretation, very high arabinose concentrations can compensate for the negative effect of ydeA transcriptional activation. Our studies (i) indicate that YdeA, when transcriptionally activated, contributes to the control of the arabinose regulon and (ii) demonstrate a new way to modulate the kinetics of induction of cloned genes.  (+info)

Phylogenetic analysis of Ara+ and Ara- Burkholderia pseudomallei isolates and development of a multiplex PCR procedure for rapid discrimination between the two biotypes. (4/706)

A Burkholderia pseudomallei-like organism has recently been identified among some soil isolates of B. pseudomallei in an area with endemic melioidosis. This organism is almost identical to B. pseudomallei in terms of morphological and biochemical profiles, except that it differs in ability to assimilate L-arabinose. These Ara+ isolates are also less virulent than the Ara- isolates in animal models. In addition, clinical isolates of B. pseudomallei available to date are almost exclusively Ara-. These features suggested that these two organisms may belong to distinctive species. In this study, the 16S rRNA-encoding genes from five clinical (four Ara- and one Ara+) and nine soil isolates (five Ara- and four Ara+) of B. pseudomallei were sequenced. The nucleotide sequences and phylogenetic analysis indicated that the 16S rRNA-encoding gene of the Ara+ biotype was similar to but distinctively different from that of the Ara- soil isolates, which were identical to the classical clinical isolates of B. pseudomallei. The nucleotide sequence differences in the 16S rRNA-encoding gene appeared to be specific for the Ara+ or Ara- biotypes. The differences were, however, not sufficient for classification into a new species within the genus Burkholderia. A simple and rapid multiplex PCR procedure was developed to discriminate between Ara- and Ara+ B. pseudomallei isolates. This new method could also be incorporated into our previously reported nested PCR system for detecting B. pseudomallei in clinical specimens.  (+info)

Substrate sequestration by a proteolytically inactive Lon mutant. (5/706)

Lon protein of Escherichia coli is an ATP-dependent protease responsible for the rapid turnover of both abnormal and naturally unstable proteins, including SulA, a cell division inhibitor made after DNA damage, and RcsA, a positive regulator of transcription. Lon is a multimer of identical 94-kDa subunits, each containing a consensus ATPase motif and a serine active site. We found that overexpressing Lon, which is mutated for the serine active site (LonS679A) and is therefore devoid of proteolytic activity, unexpectedly led to complementation of the UV sensitivity and capsule overproduction of a lon deletion mutant. SulA was not degraded by LonS679A, but rather was completely protected by the Lon mutant from degradation by other cellular proteases. We interpret these results to mean that the mutant LonS679A binds but does not degrade Lon substrates, resulting in sequestration of the substrate proteins and interference with their activities, resulting in apparent complementation. Lon that carried a mutation in the consensus ATPase site, either with or without the active site serine, was no longer able to complement a Deltalon mutant. These in vivo results suggest that the pathway of degradation by Lon couples ATP-dependent unfolding with movement of the substrate into protected chambers within Lon, where it is held until degradation proceeds. In the absence of degradation the substrate remains sequestered. Comparison of our results with those from a number of other systems suggest that proteins related to the regulatory portions of energy-dependent proteases act as energy-dependent sequestration proteins.  (+info)

Mapping an interface of SecY (PrlA) and SecE (PrlG) by using synthetic phenotypes and in vivo cross-linking. (6/706)

SecY and SecE are integral cytoplasmic membrane proteins that form an essential part of the protein translocation machinery in Escherichia coli. Sites of direct contact between these two proteins have been suggested by the allele-specific synthetic phenotypes exhibited by pairwise combinations of prlA and prlG signal sequence suppressor mutations in these genes. We have introduced cysteine residues within the first periplasmic loop of SecY and the second periplasmic loop of SecE, at a specific pair of positions identified by this genetic interaction. The expression of the cysteine mutant pair results in a dominant lethal phenotype that requires the presence of DsbA, which catalyzes the formation of disulfide bonds. A reducible SecY-SecE complex is also observed, demonstrating that these amino acids must be sufficiently proximal to form a disulfide bond. The use of cysteine-scanning mutagenesis enabled a second contact site to be discovered. Together, these two points of contact allow the modeling of a limited region of quaternary structure, establishing the first characterized site of interaction between these two proteins. This study proves that actual points of protein-protein contact can be identified by using synthetic phenotypes.  (+info)

Specific chromosome alterations in fluconazole-resistant mutants of Candida albicans. (7/706)

The exposure of Candida albicans to fluconazole resulted in the nondisjunction of two specific chromosomes in 17 drug-resistant mutants, each obtained by an independent mutational event. The chromosomal changes occurred at high frequencies and were related to the duration of the drug exposure. The loss of one homologue of chromosome 4 occurred after incubation on a fluconazole medium for 7 days. A second change, the gain of one copy of chromosome 3, was observed after exposure for 35 or 40 days. We found that the mRNA levels of ERG11, CDR1, CDR2, and MDR1, the candidate fluconazole resistance genes, remained either the same or were diminished. The lack of overexpression of putative drug pumps or the drug target indicated that some other mechanism(s) may be operating. The fluconazole resistance phenotype, electrophoretic karyotypes, and transcript levels of mutants were stable after growth for 112 generations in the absence of fluconazole. This is the first report to demonstrate that resistance to fluconazole can be dependent on chromosomal nondisjunction. Furthermore, we suggest that a low-level resistance to fluconazole arising during the early stages of clinical treatment may occur by this mechanism. These results support our earlier hypothesis that changes in C. albicans chromosome number is a common means to control a resource of potentially beneficial genes that are related to important cellular functions.  (+info)

Escherichia coli gene ydeA encodes a major facilitator pump which exports L-arabinose and isopropyl-beta-D-thiogalactopyranoside. (8/706)

Inactivation of the Escherichia coli gene ydeA, which encodes a member of the major facilitator superfamily, decreased the efflux of L-arabinose, thereby affecting the expression of AraC-regulated genes. In addition, overexpression of ydeA decreased the expression of genes regulated by isopropyl-beta-D-thiogalactopyranoside.  (+info)

Hydrolysates of plant biomass used for the production of lignocellulosic biofuels typically contain sugar mixtures consisting mainly of D-glucose and D-xylose, and minor amounts of L-arabinose. The yeast Saccharomyces cerevisiae is the preferred microorganism for the fermentative production of ethanol but is not able to ferment pentose sugars. Although D-xylose and L-arabinose fermenting S. cerevisiae strains have been constructed recently, pentose uptake is still a limiting step in mixed sugar fermentations. Here we described the cloning and characterization of two sugar transporters, AraT from the yeast Scheffersomyces stipitis and Stp2 from the plant Arabidopsis thaliana, which mediate the uptake of L-arabinose but not of D-glucose into S. cerevisiae cells. A yeast strain lacking all of its endogenous hexose transporter genes and expressing a bacterial L-arabinose utilization pathway could no longer take up and grow with L-arabinose as the only carbon source.

TY - JOUR. T1 - Effect of C-Terminal Protein Tags on Pentitol and l-Arabinose Transport by Ambrosiozyma monospora Lat1 and Lat2 Transporters in Saccharomyces cerevisiae. AU - Londesborough, John. AU - Richard, Peter. AU - Valkonen, Mari. AU - Viljanen, Kaarina. PY - 2014. Y1 - 2014. N2 - Functional expression in heterologous hosts is often less successful for integral membrane proteins than for soluble proteins. Here, two Ambrosiozyma monospora transporters were successfully expressed in Saccharomyces cerevisiae as tagged proteins. Growth of A. monospora on l-arabinose instead of glucose caused transport activities of l-arabinose, l-arabitol, and ribitol, measured using l-[1-3H]arabinose, l-[14C]arabitol, and [14C]ribitol of demonstrated purity. A. monospora LAT1 and LAT2 genes were cloned earlier by using their ability to improve the growth of genetically engineered Saccharomyces cerevisiae on l-arabinose. However, the l-arabinose and pentitol transport activities of S. cerevisiae carrying LAT1 ...

We have constructed a series of plasmid vectors (pBAD vectors) containing the PBAD promoter of the araBAD (arabinose) operon and the gene encoding the positive and negative regulator of this promoter, araC. Using the phoA gene and phoA fusions to monitor expression in these vectors, we show that the ratio of induction/repression can be 1,200-fold, compared with 50-fold for PTAC-based vectors. phoA expression can be modulated over a wide range of inducer (arabinose) concentrations and reduced to extremely low levels by the presence of glucose, which represses expression. Also, the kinetics of induction and repression are very rapid and significantly affected by the ara allele in the host strain. Thus, the use of this system which can be efficiently and rapidly turned on and off allows the study of important aspects of bacterial physiology in a very simple manner and without changes of temperature. We have exploited the tight regulation of the PBAD promoter to study the phenotypes of null ...

D-Xylose or L-arabinose-consuming S. cerevisiae strains have previously been independently developed by introduction of heterologous enzymes necessary for the assimilation of either of the sugars [6, 7, 10-12]. However, co-fermentation of the two pentose sugars by S. cerevisiae has not, to the best of our knowledge, previously been reported. We have introduced both the arabinose and the xylose pathways in S. cerevisiae strains to investigate the effects and possible limitations of the combined metabolism of the two pentoses. Xylose utilization was enabled by overexpression of the P. stipitis genes coding for XR and XDH as well as the endogenous XK through chromosomal integration. Arabinose assimilation was enabled through heterologous expression of the bacterial arabinose pathway consisting of L-arabinose isomerase (AraA), L-ribulokinase (AraB) and L-ribulose-5-P-4-epimerase (AraD) genes.. The combination of xylose and arabinose pathways was first tested in a laboratory strain. However, ...

Figure 2 and 3 indicate the RFP output normalized with growth ratio (OD) at different levels of arabinose. Figure 1 shows that CpxR-I13507 is activated at the highest level when MalE31, the periplasmic misfolder, is expressed. This occurs around 0.2% arabinose concentration. Similar trends are observed in the case of MalE which is a periplasmic folder. MalE and MalE31 activate the system at different levels. MalE31 has similar trends to MalE but has a higher level of RFP expression. These results prove that MalE and MalE31 can both activate the CpxR system however, MalE31, which misfolds, activates it more rapidly and at a lower level of arabinose concentration compared to MalE. If the line of best fit is studied, it is seen that MalE has very minimal level of Cpx activation. Whereas, malE31 has a linear regression which flattens out as the system reaches its upper threshold of detection. Biologically, this could mean that the MalE31 is activated at levels that saturate the cellular chaperones ...

Production and Utilization of L-Arabinose in ChinaProduction and Utilization of L-Arabinose in China
L-arabinose is a newly developed low-caloric monosaccharide, which has many biomedical and health effects, especially intestinal sucrase inhibition effect. L-arabinose is mainly produced by chemical or enzymatic hydrolysis of hemicellulose. The taste of L-arabinose is quite similar to that of sucrose, with approximately 50% of the sweetness. As a functional additive, L-arabinose can be used in medical and pharmaceutical applications for the treatment of diseases such as diabetes, chronic constipation, mineral absorption disorder and secondary bile acid formation disorder. However, L-arabinose has not been widely used in functional foods due to high price and lack of publicity and guidance. A comprehensive review of L-arabinose physicochemical properties, production, applications field, market statue and development direction is presented in this paper.

YidC is a polytopic inner membrane protein with a molecular mass of 60 kDa. To facilitate its purification, a histidine tag was introduced at the C‐terminus of YidC, and the gene was placed under control of the lac promoter yielding the expression vector pEH1hisYidC. To determine whether His‐tagged YidC is functional in vivo, pEH1hisYidC was transformed to the YidC depletion strain JS7131 (Samuelson et al., 2000). In this strain, the chromosomal yidC gene is disrupted and an intact yidC gene under control of the araBAD promoter has been introduced. JS7131 is not viable on Luria-Bertani (LB) agar plates containing 0.2% glucose, since under these conditions expression of yidC from the araBAD promoter is tightly repressed. Transformation with pEH1hisYidC restored growth of JS7131 in the presence of glucose (Figure 1A), indicating that plasmid‐encoded, His‐tagged YidC is functional. For overproduction, pEH1hisYidC was transformed to strain E. coli SF100 (Baneyx and Georgiou, 1990). YidC ...

In theory, this genetic construction is able to detect different concentrations of a compound provided that you have three different promoters that are sensitive to different concentrations of the substance. Based on the amount of compound detected, the bacteria will produce one of three reporter proteins. For our project, we decided to use the same sensors and reporter proteins that the University of British Columbia team used in their 2009 iGEM project. Therefore we began with 3 promoters: pBAD wild type, pBAD weak and pBAD strong; each promoter was able to detect arabinose at different concentrations. Our reporter proteins were GFP, YFP, and RFP (Cherry). We arranged the constructions so that GFP is produced when the cells were induced with low concentrations of arabinose, YFP is produced when induced with medium concentrations and RFP (Cherry) is produced when there is a high concentration. The mechanism that enables this behavior will be explained in two parts, the first part involves the ...

Design of Screening Plasmid 1.0: We are using the Pbad arabinose-inducible induction system [1] as a tunable input. GFP is a measure of input and RFP is a measure of output. A Biobricks cloning site enables easy insertion of any Biobricks part. RNase E sites create independence between the mRNA stability of the device being screened and the mRNA stability of the fluorescent proteins. In particular, we suspect mRFP1 contains internal RNaseE cut sites and have added a hairpin 5 of the coding region to slow degradation by RNase E. [2 ...

THE BINDING OF SUGARS TO THE L-ARABINOSE-BINDING PROTEIN FROM ESCHERICHIA COLITHE BINDING OF SUGARS TO THE L-ARABINOSE-BINDING PROTEIN FROM ESCHERICHIA COLI
The sugar-binding site of the L-arabinose binding protein, an essential component of the high-affinity L-arabinose uptake system in Escherichia coli, is located deep in a cleft formed by the two domains of the protein. The site was unambiguously identified with the electron-rich substrate analog 6-bromo-6-deoxy-D-galactose in a difference Fourier analysis. The observation that the original structure might have been solved with bound L-arabinose necessitated the synthesis of the heavy-atom analog, its structure consistent with the sugar-binding specificity of the protein. Difference Fourier maps showed a peak which was partially coincident with the extraneous density found in the native map. This extraneous density was previously attributed to a bound L-arabinose molecule, and its presence accounts for early failures of difference Fourier analyses of crystals soaked in or co-crystallized with L-arabinose to locate the binding site. The location of a C6 substituent by difference Fourier ...

A novel L-arabinose-responsive regulator found in the rice-blast fungus Pyricularia oryzae (Magnaporthe oryzae) - omicXA novel L-arabinose-responsive regulator found in the rice-blast fungus Pyricularia oryzae (Magnaporthe oryzae) - omicX
In this study we identified the L-arabinose-responsive regulator of Pyricularia oryzae that regulates L-arabinose release and catabolism. Previously we identified the Zn2Cys6 transcription factor (TF) AraR that has this role in the Trichocomaceae family (Eurotiales), but is absent in other fungi. Candidate Zn2Cys6 TF genes were selected according to their transcript profiles on L-arabinose. Deletion mutants of these genes were screened for their growth phenotype on L-arabinose. One mutant, named Δara1, was further analyzed. Our analysis demonstrated that Ara1 from P. oryzae is the functional homolog of AraR from A. niger, while sequence analysis did not reveal significant homology between them.

Lignocellulosic biomass yields after hydrolysis, besides the hexose D-glucose, D-xylose, and L-arabinose as main pentose sugars. In second generation bioethanol production utilizing the yeast Saccharomyces cerevisiae, it is critical that all three sugars are co-consumed to obtain an economically feasible and robust process. Since S. cerevisiae is unable to metabolize pentose sugars, metabolic pathway engineering has been employed to introduce the respective pathways for D-xylose and L-arabinose metabolism. However, S. cerevisiae lacks specific pentose transporters, and these sugars enter the cell with low affinity via glucose transporters of the Hxt family. Therefore, in the presence of D-glucose, utilization of D-xylose and L-arabinose is poor as the Hxt transporters prefer D-glucose. To solve this problem, heterologous expression of pentose transporters has been attempted but often with limited success due to poor expression and stability, and/or low turnover. A more successful approach is the ...

Conditional gene expression systems are useful tools for studying the role of essential or toxic gene products in bacterial systems. There is a paucity of such systems available for use in the mycobacteria. The utility of the Escherichia coli arabinose-inducible system was looked into, since it is tightly controlled in response to the presence of arabinose and glucose. It was demonstrated that the P(BAD) promoter can be used to express heterologous genes in Mycobacterium smegmatis. Expression of a lacZ reporter gene demonstrated that promoter activity was inducible in response to the presence of glucose, but only on solid medium. This system was utilized to study the functional consequences of expressing one member of a putative toxin-antitoxin pair (Rv1991c). Rv1991c has homology with a number of bacterial toxins, including ChpK, MazF and PemK. A potential antitoxin gene has been identified, adjacent to Rv1991c in the genome, which was coexpressed with the toxin. Expression of the toxin alone inhibited

The characterization of this construction was made on an E.coli strain in a semi quantitative attempt. In that way, we expected that only araC was repressing the promoter because the xylR binding sites corresponds to xylR of B. subtilis. Since it requires sugars for its expression, and the system is repressed by a metabolite from the pentose metabolism pathway, we used a minimal medium, M9 (Sambrook, 1989), but we changed the glucose for arginine as carbon source in order to get the lowest interference in the expression of GFP from another monosaccharides species in the medium. We use a gradient for both, xylose and arabinose on cultures at 0.1 O.D (540 nm). We could see that the expression of GFP increases as the amount of sugars added also increases. An amount of 0.01% (g/ml) of arabinose is enough for an increase of 4 times the basal expression, and the maximum production is approximately 5 times greater for the downstream genes with 0.1%(g/ml) of arabinose. Xylose gradient had a small ...

With the parameter estimates generated from a nonlinear regression, the model displays a decrease in GFP fluorescence as induction levels of arabinose and theophylline are increased. Furthermore, the effect of the relative promoter strength is accurately reflected in the graphs generated by the model. A small relative promoter strength results in a a lower baseline fluorescence under conditions of no repression, and lower fluorescence levels across all ranges of arabinose and theophylline. This model may be used to approximate the behavior of systems under control of Anderson promoters that have been engineered to be repressible by our synthetic transcription factors, to a certain degree of accuracy. Below is our experimental data for five Anderson promoters with their reported relative promoter strengths, presented in terms of relative GFP fluorescence ...

Interpretive Summary: Arabinoxylans have a unique structure, which contributes to their important function in plant physiology and end-use quality. The complex and heterogeneous structure leads to two very diverse fractions based on water extractability. These two fractions, WEAX and WUAX, differ in their physical properties with respect to arabinose substitution and molecular weight. This results in varied influence on end-use quality. The genetic and environmental influences on arabinoxylan molecules does not conclusively suggest complete genetic or environmental control over the abundance or structure of the molecules. Because of these varied results across many studies, and the highly variable nature of arabinoxylan influence over end-use quality, there is a wealth of research that may still be undertaken to further understand the complex nature of arabinoxylan molecules. Technical Abstract: Recent attention to dietary fiber in wheat (Triticum aestivum L.) has invigorated research in the ...
