Two cDNA clones encoding cytochrome P450 enzymes belonging to the CYP79 family have been isolated from Triglochin maritima. The two proteins show 94% sequence identity and have been designated CYP79E1 and CYP79E2. Heterologous expression of the native and the truncated forms of the two clones in Escherichia coli demonstrated that both encode multifunctional N-hydroxylases catalyzing the convers...
An endonuclease IV homolog was identified as the product of a conceptual open reading frame in the genome of the hyperthermophilic bacterium Thermotoga maritima. The T. maritima endonuclease IV gene encodes a 287-amino-acid protein with 32% sequence identity to Escherichia coli endonuclease IV. The gene was cloned, and the expressed protein was purified and shown to have enzymatic activities th...
High-throughput sequencing of microbial genomes has allowed the application of functional genomics methods to species lacking well-developed genetic systems. For the model hyperthermophile Thermotoga maritima, microarrays have been used in comparative genomic hybridization studies to investigate diversity among Thermotoga species. Transcriptional data have assisted in prediction of pathways for...
بیماری ریزومانیا (Rhizomania) در حال حاضر یکی از مهمترین بیماریهای چغندرقند در دنیا است. در تحقیق حاضر آلودگی تعدادی از علفهای هرز مهم مزارع چغندرقند در شرایط آلودگی طبیعی به ویروس عامل بیماری (Beet necrotic yellow vein virus, BNYVV) در مرکز تحقیقات کشاورزی و منابع طبیعی استان فارس بررسی شد. بدین منظور ریشه علفهای هرز موجود در مزارع چغندرقند آلوده به بیماری ریزومانیا جمع آوری و برای ردیابی...
In the allosteric aspartate transcarbamylase (ATCase) from the hyperthermophilic eubacterium Thermotoga maritima, the catalytic and regulatory functions, which in class B ATCases are carried out by specialized polypeptides, are combined on a single type of polypeptide assembled in trimers. The ATCases from T. maritima and Treponema denticola present intriguing similarities, suggesting horizonta...
Exonuclease VII was first identified in 1974 as a DNA exonuclease that did not require any divalent cations for activity. Indeed, Escherichia coli ExoVII was identified in partially purified extracts in the presence of EDTA. ExoVII is comprised of two subunits (XseA and XseB) that are highly conserved and present in most sequenced prokaryotic genomes, but are not seen in eukaryotes. To better u...
Occurrence of the hsp70 (dnaK) gene was investigated in various members of the domain Archaea comprising both euryarchaeotes and crenarchaeotes and in the hyperthermophilic bacteria Aquifex pyrophilus and Thermotoga maritima representing the deepest offshoots in phylogenetic trees of bacterial 16S rRNA sequences. The gene was not detected in 8 of 10 archaea examined but was found in A. pyrophil...
Myriapods (e.g., centipedes and millipedes) display a simple homonomous body plan relative to other arthropods. All members of the class are terrestrial, but they attained terrestriality independently of insects. Myriapoda is the only arthropod class not represented by a sequenced genome. We present an analysis of the genome of the centipede Strigamia maritima. It retains a compact genome that ...
Strigamia maritima (Myriapoda; Chilopoda) is a species from the soil-living order of geophilomorph centipedes. The Geophilomorpha is the most speciose order of centipedes with over a 1000 species described. They are notable for their large number of appendage bearing segments and are being used as a laboratory model to study the embryological process of segmentation within the myriapods. Using ...
