Overproduction, crystallization and X-ray diffraction data analysis of ectoine synthase from the cold-adapted marine bacterium Sphingopyxis alaskensis.
Ectoine biosynthetic genes (ectABC) are widely distributed in bacteria. Microorganisms that carry them make copious amounts of ectoine as a cell protectant in response to high-osmolarity challenges. Ectoine synthase (EctC; EC 4.2.1.108) is the key enzyme for the production of this compatible solute and mediates the last step of ectoine biosynthesis. It catalyzes the ring closure of the cyclic e...
متن کاملSpecific growth rate plays a critical role in hydrogen peroxide resistance of the marine oligotrophic ultramicrobacterium sphingomonas alaskensis strain RB2256.
The marine oligotrophic ultramicrobacterium Sphingomonas alaskensis RB2256 has a physiology that is distinctly different from that of typical copiotrophic marine bacteria, such as Vibrio angustum S14. This includes a high level of inherent stress resistance and the absence of starvation-induced stress resistance to hydrogen peroxide. In addition to periods of starvation in the ocean, slow, nutr...
متن کاملSphingopyxis chilensis sp. nov., a chlorophenol-degrading bacterium that accumulates polyhydroxyalkanoate, and transfer of Sphingomonas alaskensis to Sphingopyxis alaskensis comb. nov.
The taxonomic position of a chlorophenol-degrading bacterium, strain S37T, was investigated. The 16S rDNA sequence indicated that this strain belongs to the genus Sphingopyxis, exhibiting high sequence similarity to the 16S rDNA sequences of Sphingomonas alaskensis LMG 18877T (98.8%), Sphingopyxis macrogoltabida LMG 17324T (98.2%), Sphingopyxis terrae IFO 15098T (95%) and Sphingomonas adhaesiva...
متن کاملDraft Genome Sequence of Sphingopyxis sp. Strain MWB1, a Crude-Oil-Degrading Marine Bacterium
Sphingopyxis sp. strain MWB1, which is capable of degrading crude oil, diesel, and kerosene, was isolated from crude oil-contaminated seashore in Tae-an, South Korea. Here, we report the draft genome sequence of this strain, which comprises 3,118,428 bp with a G+C content of 62.85 mol%.
متن کاملSphingopyxis soli sp. nov., isolated from landfill soil.
A Gram-negative, aerobic, rod-shaped, motile, oxidase-positive, catalase-negative bacterium, designated strain BL03(T), was isolated from landfill soil in Pohang, Republic of Korea. Colonies on Luria-Bertani agar plates were yellow. The strain grew in the presence of 0-3 % (w/v) NaCl, at 15-42 degrees C and at pH 5.0-9.5. The predominant ubiquinone was Q-10, and the major cellular fatty acids w...
