On a 4.7-kbp HindIII clone of Thermus strain ZO5 DNA, complementing an aspartate carbamoyltransferase mutation in Escherichia coli, we identified a cluster of four potential open reading frames corresponding to genes pyrR, and pyrB, an unidentified open reading frame named bbc, and gene pyrC. The transcription initiation site was mapped at about 115 nucleotides upstream of the pyrR translation ...
A yellow-pigmented strain of the genus Thermus, with optimum growth temperatures about 65 approximately 70 degrees C, was isolated from the hot springs in Rehai of Tengchong, Yunnan Province, China. Morphological, physiological and biochemical characteristics, pigment analysis of RH99-GF7504 strain and its phylogenetic analysis of 16S rDNA showed that this organism represented a new species of ...
Significant progress has been made in isolating novel alkaline β-mannanases, however, there is a paucity of information concerning the structural basis for alkaline tolerance displayed by these β-mannanases. We report the catalytic domain structure of an industrially important β-mannanase from the alkaliphilic Bacillus sp. N16-5 (BSP165 MAN) at a resolution of 1.6 Å. This enzyme, classified int...
(a) BlCel5B in the crystallographic and closed configuration; (b) Bacillus halodurans Cel5B (BhCel5B) (PDB id: 4V2X) (c) Piromyces rhizinflata GH5 endoglucanase (PDB id: 3AYR); (d) Clostridium cellulolyticum GH5 endoglucanase (PDB id: 1EDG); (e) Clostridium cellulovorans GH5 endoglucanase (PDB id: 3NDY); (f) Bacteroides ovatus GH5 xyloglucanase (PDB id: 3ZMR); (g) Paenibacillus pabuli GH5 xylog...
آنزیم متیل¬گلی¬اکسال¬سنتاز واکنش تبدیل دی¬هیدروکسی¬استون¬فسفات را به متیل¬گلی¬اکسال انجام می-دهد. این آنزیم هموهگزامر بوده و فسفات مهار¬کننده آلوستریک آن می¬باشد. این آنزیم اولین¬بار از باکتری اشرشیاکلی جداسازی و مطالعه شده است. بررسی ساختار کریستال mgs اشرشیاکلی نشان می¬دهد که پل¬نمکی ایجاد شده بین آسپارتیک¬اسید20 با آرژنین150 در حضور فسفات، در انتقال تغییرات آلوستریکی در آنزیم نقش دارد. اخیرا...
Thermus sp. isolate 2.9 was obtained from a hot water spring in Salta, Argentina. Here, we report the draft genome sequence (2,485,434 bp) of this isolate, which consists of 11 scaffolds of >10 kbp and 2,719 protein-coding sequences.
Linker histones are essential for DNA compaction in chromatin. They bind to nucleosomes in a 1:1 ratio forming chromatosomes. Alternative configurations have been proposed in which the globular domain of the linker histone H5 (gH5) is positioned either on- or off-dyad between the nucleosomal and linker DNAs. However, the dynamic pathways of chromatosome assembly remain elusive. Here, we studied...
