An extremely thermostable xylanase from the thermophilic eubacterium Thermotoga.
Endo-1,4-beta-xylanase (EC 3.2.1.8) was isolated from the culture supernatant of Thermotoga sp. strain FjSS3-B.1, an extremely thermophilic anaerobic eubacterium which grows optimally at 80 degrees C. Activity was purified 165-fold by anion-exchange and hydroxyapatite chromatography. The enzyme has an Mr of 31,000 as determined by SDS/PAGE and 35,000 by analytical gel filtration. The optima for...
متن کاملThe organization and expression of essential transcription translation component genes in the extremely thermophilic eubacterium Thermotoga maritima.
A 5789-nucleotide-long EcoRI fragment from the genome of Thermotoga maritima, identified by cross-hybridization to L11, L1, L10, and L12 ribosomal protein gene sequences from Escherichia coli, was cloned and sequenced. The fragment encodes five tRNAs (tRNA(met1), anticodon complementary to AUG; tRNA(met2), AUG; tRNA(thr), ACA; tRNA(tyr), UAC; tRNA(trp), UGG), the transcription termination-antit...
متن کاملThe extremely thermophilic eubacterium, Thermotoga maritima, contains a novel iron-hydrogenase whose cellular activity is dependent upon tungsten.
Thermotoga maritima is the most thermophilic eubacterium currently known and grows up to 90 degrees C by a fermentative metabolism in which H2, CO2, and organic acids are end products. It was shown that the production of H2 is catalyzed by a single hydrogenase located in the cytoplasm. The addition of tungsten to the growth medium was found to increase both the cellular concentration of the hyd...
متن کاملPreliminary X-ray crystallographic analysis of tRNA pseudouridine 55 synthase from the thermophilic eubacterium Thermotoga maritima.
Thermotoga maritima TruB, an enzyme responsible for the formation of pseudouridine in tRNA, has been purified and crystallized by the hanging-drop vapour-diffusion method in 100 mM citrate pH 3.5, 200 mM Li(2)SO(4), 20% glycerol, 13% PEG 8000. Crystals display orthorhombic symmetry, with unit-cell parameters a = 47.39, b = 83.88, c = 98.72 A, and diffract to 2.0 A resolution using synchrotron r...

چکیده : قرآن چشمه سار زلال هدایتی است که از سوی خداوند حکیم نازل شده تا بشر را به سر منزل کمال برساند. و در این راستا از شیوه های گوناگون بیانی خطابی و بلاغی استفاده کرده تا با فطرت زیبا طلب انسان درآمیزد و اورا مقهور خویش ساخته، به سوی کمالات سوق دهد.ازجمله جنبه های بارز اعجاز بیانی قرآن وجود فواصل در پایان آیات است که کار برد سجع و قافیه در کلام بشر شبیه آن است. برخی ازعلمای سلف تفاوت هایی ب...
