Transhydrogenase and Growth Substrate Influence Lipid Hydrogen Isotope Ratios in Desulfovibrio alaskensis G20
Microbial fatty acids preserve metabolic and environmental information in their hydrogen isotope ratios ((2)H/(1)H). This ratio is influenced by parameters that include the (2)H/(1)H of water in the microbial growth environment, and biosynthetic fractionations between water and lipid. In some microbes, this biosynthetic fractionation has been shown to vary systematically with central energy met...
متن کاملEffects of transhydrogenase and growth substrates on lipid D/H ratios in Desulfovibrio alaskensis G20
20 Microbial fatty acids preserve metabolic and environmental information in their ratios of 21 deuterium (D) to hydrogen (H). This ratio is influenced by parameters that include the 22 D/H of water in the microbial growth environment, and biosynthetic fractionations 23 between water and lipid. In some microbes, this biosynthetic fractionation has been 24 shown to vary systematically with centr...
متن کاملNew model for electron flow for sulfate reduction in Desulfovibrio alaskensis G20.
To understand the energy conversion activities of the anaerobic sulfate-reducing bacteria, it is necessary to identify the components involved in electron flow. The importance of the abundant type I tetraheme cytochrome c3 (TpIc3) as an electron carrier during sulfate respiration was questioned by the previous isolation of a null mutation in the gene encoding TpIc3, cycA, in Desulfovibrio alask...
متن کاملTupA: A Tungstate Binding Protein in the Periplasm of Desulfovibrio alaskensis G20
The TupABC system is involved in the cellular uptake of tungsten and belongs to the ABC (ATP binding cassette)-type transporter systems. The TupA component is a periplasmic protein that binds tungstate anions, which are then transported through the membrane by the TupB component using ATP hydrolysis as the energy source (the reaction catalyzed by the ModC component). We report the heterologous ...
متن کاملMultiple sulfur isotope signatures of sulfite and thiosulfate reduction by the model dissimilatory sulfate-reducer, Desulfovibrio alaskensis str. G20
Dissimilatory sulfate reduction serves as a key metabolic carbon remineralization process in anoxic marine environments. Sulfate reducing microorganisms can impart a wide range in mass-dependent sulfur isotopic fractionation. As such, the presence and relative activity of these organisms is identifiable from geological materials. By extension, sulfur isotope records are used to infer the redox ...
