Abstract:
The bifunctional alcohol/aldehyde dehydrogenase (AdhE) comprises both an N-terminal aldehyde dehydrogenase (AldDH) and a C-terminal alcohol dehydrogenase (ADH). In vivo, full-length AdhE oligomerizes into long oligomers known as spirosomes. However, structural analysis of AdhE is challenging owing to the heterogeneity of the spirosomes. Therefore, the domains of AdhE are best characterized separately. Here, the structure of ADH from the pathogenic Escherichia coli O157:H7 was determined to 1.65 Å resolution. The dimeric crystal structure was confirmed in solution by small-angle X-ray scatterin

Abstract:
Bifunctional alcohol/aldehyde dehydrogenase (ADHE) enzymes are found within many fermentative microorganisms. They catalyse the conversion of an acyl-coenzyme A to an alcoholviaan aldehyde intermediate; this is coupled to the oxidation of two NADH molecules to maintain the NAD+pool during fermentative metabolism. The structure of the alcohol dehydrogenase (ADH) domain of an ADHE protein from the ethanol-producing thermophileGeobacillus thermoglucosidasiushas been determined to 2.5 Å resolution. This is the first structure to be reported for such a domain.In silicomodelling has been carried out

Abstract:
A bacterial strain, designated RHs22T, was isolated from a soil sample cultivated with rice in the Suwon region of South Korea. The cells were aerobic, Gram-stain-negative, non-spore-forming, non-flagellated rods or occasionally filaments. The strain grew at 10–37 °C (optimum, 28–30 °C), at pH 5.0–10.0 (optimum, 7.0) and in the presence of 0–1 % (w/v) NaCl (optimum, 0 %). Phylogenetically, the strain was closely related to members of the genus Spirosoma , as its 16S rRNA gene sequence had similarity of 90.3–92.1 % with respect to those of members of the genus Spirosoma , showing the highest se

Abstract:
A Gram-reaction-negative, yellow-pigmented strain, designated EX36T, was characterized using a polyphasic approach comprising phylogenetic, morphological and genotypic analyses. The endophytic strain was isolated from Zn/Cd-accumulating Salix caprea in Arnoldstein, Austria. Analysis of the 16S rRNA gene demonstrated that the novel strain is most closely related to members of the genus Spirosoma (95 % sequence similarity with Spirosoma linguale ).

Abstract:
A bacterial strain, designated MSd3T, was isolated from a freshwater sample collected from the Hosoda River in Japan. The cells of strain MSd3T were Gram-stain-negative, non-spore-forming, aerobic, non-motile, curved rods forming rings, coils and undulating filaments. The 16S rRNA gene sequence of strain MSd3T showed closest similarity to that of Spirosoma linguale DSM 74T (97.6 % similarity) and similarity to other members of the genus Spirosoma ranged from 90.3 to 95.9 %. Strain MSd3T contained menaquinone 7 as the sole respiratory quinone. The major cellular fatty acids were summed feature

Cette toxine est considérée comme un facteur de virulence majeur d’H. pylori. Elle interagit avec des protéines de l’hôte, perturbant la signalisation cellulaire et entraînant des modifications pouvant favoriser le développement de maladies gastrointestinales,
