Although tidal marshes are known for their coastal defense function during storm surges, the impact of extreme wave forcing on marsh development is poorly understood. Seedling survival in first season after germination, which may involve exposure to events, crucial natural establishment and human restoration marshes. We hypothesize that species-specific plant traits plays a significant role see...
The data provide additional support of the characterization of the biophysical and biochemical properties of the enzyme acetohydroxyacid synthase from the hyperthermophilic bacterium Thermotoga maritima (Eram et al., 2015) [1]. The genes encoding the enzyme subunits have been cloned and expressed in the mesophilic host Escherichia coli. Detailed data include information about the optimization o...
Sir, I read with interest the article Enhancing digital images using unsharp-mask by Taneja.[1] The author has discussed a really interesting aspect of dermatological photography. The use of a sharpening tool is definitely helpful in enhancing communication via images, especially in the context of seeing images on the monitor screens, like in teledermatology, but whether and to what extent th...
Functional Studies of 5-Carboxyaminoimidazole Ribonucleotide Synthetaseand Mutase from Thermotoga maritima
We report for the first time that marine angiosperms (seagrasses) possess sulfated polysaccharides, which are absent in terrestrial and freshwater plants. The structure of the sulfated polysaccharide from the seagrass Ruppia maritima was determined. It is a sulfated D-galactan composed of the following regular tetrasaccharide repeating unit: [3-beta-D-Gal-2(OSO3)-1-->4-alpha-D-Gal-1-->4-alpha-D...
The relation between the level of genetic variation and the rate of recombination per physical unit was investigated in sea beet (Beta vulgaris subsp. maritima). The rate of recombination per physical unit was estimated indirectly through marker density in an RFLP linkage map of sugar beet. From this map, we also selected RFLP markers covering two of the nine chromosomes in Beta. The markers we...
A 110-residue protein encoded by the TM1442 gene of Thermotoga maritima shows amino-acid sequence similarity to Bacillus subtilis anti-anti-sigma factors RsbV and SpoIIAA. It has been overexpressed in Escherichia coli and the recombinant protein exists primarily as both a monomer and a dimer in solution. The dimeric form has been crystallized using polyethylene glycol (PEG) 8000 as a precipitan...
The use of waste materials as organic amendments in soil remediation can affect metal solubility; this interaction will vary with the characteristics of the organic matter that is added to the soil. A pot experiment was carried out in a calcareous, metal-polluted soil, using Beta maritima L. as an indicator species for the treatment effects on metal solubility. The treatments were: fresh solid ...
A novel aminoacyl-tRNA synthetase that contains an iron-sulfur cluster in the tRNA anticodon-binding region and efficiently charges tRNA with tryptophan has been found in Thermotoga maritima. The crystal structure of TmTrpRS (tryptophanyl-tRNA synthetase; TrpRS; EC 6.1.1.2) reveals an iron-sulfur [4Fe-4S] cluster bound to the tRNA anticodon-binding (TAB) domain and an L-tryptophan ligand in the...
MOTIVATION One of the most successful methods to date for recognizing protein sequences that are evolutionarily related has been profile hidden Markov models (HMMs). However, these models do not capture pairwise statistical preferences of residues that are hydrogen bonded in beta sheets. These dependencies have been partially captured in the HMM setting by simulated evolution in the training ph...
