Removal of long-chain hydrocarbons and n-alkanes from oil-contaminated environments are mere important to reduce the ecological damages, while bio-augmentation is a very promising technology that requires highly efficient microbes. In present study, the efficiency of pure isolates, i.e., Geobacillus thermoparaffinivorans IR2, Geobacillus stearothermophillus IR4 and Bacillus licheniformis MN6 an...
Octaprenyl pyrophosphate synthase (OPPs) catalyzes the chain elongation of farnesyl pyrophosphate (FPP) via consecutive condensation reactions with five molecules of isopentenyl pyrophosphate (IPP) to generate all-trans C40-octaprenyl pyrophosphate. The polymer forms the side chain of ubiquinone that is involved in electron transport system to produce ATP. Our previous study has demonstrated th...
AIMS/HYPOTHESIS Polymorphisms in the transcription factor 7-like 2 (TCF7L2) gene have been shown to display a powerful association with type 2 diabetes. The aim of the present study was to evaluate metabolic alterations in carriers of a common TCF7L2 risk variant. METHODS Seventeen non-diabetic subjects carrying the T risk allele at the rs7903146 TCF7L2 locus and 24 subjects carrying no risk ...
The cardiac phosphoprotein phospholemman (PLM) regulates the cardiac sodium pump, activating the pump when phosphorylated and inhibiting it when palmitoylated. Protein palmitoylation, the reversible attachment of a 16 carbon fatty acid to a cysteine thiol, is catalyzed by the Asp-His-His-Cys (DHHC) motif-containing palmitoyl acyltransferases. The cell surface palmitoyl acyltransferase DHHC5 reg...
[structure: see text] A sequence of chemoselective cross-metathesis reactions and enantioselective allyltitanations of aldehydes has been used to prepare the C1-C13, C15-C26, and C27-C40 fragments of tetrafibricin.
Carotenoids could be divided into C30 carotenoids and C40 carotenoids. The immune functions of C40 carotenoids had been extensively researched, while those of C30 carotenoids still remain unclear. In this study, the immune functions of a biosynthetic C30 carotenoid, 4,4'-diaponeurosporene (Dia), were identified on dendritic cells (DCs). DCs treated with 1 μM Dia for 24 h showed morphologic and ...
1. Chloroplasts prepared by the non-aqueous technique will, after fragmentation by ultrasonic treatment, incorporate [2-14C]mevalonic acid into phytoene, the first C40 compound formed in the biosynthetic sequence to coloured carotenoids. 2. With suspensions containing 3*5mg. of chlorophyll, the optimum amounts of cofactor required were ATP (10,umoles), magnesium chloride (20,umoles) and glutath...
The properties of alkanes in the C20 – C40 mass range are of fundamental importance in industrial applications as they are important constituents of synthetic lubricant base stocks. In an extension to earlier work on alkanes in the C20–C40 carbon number range we present the results of molecular simulations for 9-octylheptadecane, a starlike isomer of C25 . Both equilibrium ~EMD! and nonequilibr...
