    Description / Table of Contents: This book covers the occurrence of a wide variety of metal-carbon bonds in living organisms, ranging from bacteria to humans, The occurrence of a wide variety of metal-carbon bonds in living organisms, ranging from bacteria to humans, is only recently recognized. Of course, the historical examples are the B12 coenzymes containing cobalt-carbon bonds, but now such bonds are also known for nickel, iron, copper, and other transition metal ions. There is no other comparable book; MILS-6, written by 17 experts, summarizes the most recent insights into this fascinating topic

    Raw materials for future energy supply (2018)
    Springer International
    In:  Springer International, Cham, X, 150 pp. ISBN 978-331991229-5; 978-331991228-8
    Details
    Publication Date: 2021-02-08
    Description: This is the first book that analyses the future raw materials supply from the demand side of a society that chiefly relies on renewable energies, which is of great significance for us all. It addresses primary and secondary resources and substitution, not only from technical but also socioeconomic and ethical points of view. The "Energiewende" (Energy Transition) will change our consumption of natural resources significantly. When in future our energy requirements will be covered mostly by wind, solar power and biomass, we will need less coal, oil and natural gas. However, the consumption of minerals, especially metallic resources, will increase to build wind generators, solar panels or energy storage facilities. Besides e.g. copper, nickel or cobalt, rare earth elements and other high-tech elements will be increasingly used. With regard to primary metals, Germany is 100 % import dependent; only secondary material is produced within Germany. Though sufficient geological primary resources exist worldwide, their availability on the market is crucial. The future supply of the market is dependent on the development of prices, the transparency of the market and the question of social and ethical standards in the raw materials industry, as well as the social license to operate, which especially applies to mining. The book offers a valuable resource for everyone interested in the future raw material supply of our way of life, which will involve more and more renewable energies.

    The DNA binding protein Tfx from Methanobacterium thermoautotrophicum: structure, DNA binding properties and transcriptional regulation (1999)

    Notes: In Methanobacterium thermoautotrophicum, the fmdECB operon encoding the molybdenum formylmethanofuran dehydrogenase is directly preceded by an open reading frame tfx predicted to encode a DNA binding protein. The 16.1 kDa protein has an N-terminal basic domain with a helix–turn–helix motif for DNA binding and a C-terminal acidic domain possibly for transcriptional activation. We report here on the DNA binding properties of the Tfx protein heterologously overproduced in Escherichia coli. Tfx was found to bind specifically to a DNA sequence downstream of the promoter of the fmdECB operon, as shown by electrophoretic mobility shift assays and DNase I footprint analysis. Northern blot hybridizations revealed that transcription of tfx is repressed during the growth of M. thermoautotrophicum in the presence of tungstate. Based on its structure and properties, the DNA binding protein Tfx is proposed to be a transcriptional regulator composed of a basic DNA binding domain and an acidic activation domain.

    A selenium-dependent and a selenium-independent formylmethanofuran dehydrogenase and their transcriptional regulation in the hyperthermophilic Methanopyrus kandleri (1997)
    Oxford BSL : Blackwell Science Ltd
    Molecular microbiology 23 (1997), S. 0 
    Details

    Topics: Biology , Medicine
    Notes: The genome of Methanopyrus kandleri was found to harbour a gene, fwuB, predicted to encode the catalytic subunit of a tungsten formylmethanofuran dehydrogenase with an active site selenocysteine, and a second gene, fwcB, encoding a tungsten formylmethanofuran dehydrogenase with an active site cysteine. Northern blot and primer-extension analysis revealed that both genes were differentially transcribed. During growth of the methanogen on medium supplemented with selenium only fwuB was transcribed, whereas transcription of both fwuB and fwcB was observed on selenium-deprived medium. Growth of M. kandleri was stimulated by tungstate and selenite but not by molybdate. The findings indicate that the hyperthermophilic archaeon contains two tungsten isoenzymes of formylmethanofuran dehydrogenase, one of which is a novel selenium enzyme. They also indicate that the hyperthermophilic methanogen probably does not contain a molybdenum formylmethanofuran dehydrogenase which appears to be present only in thermophilic and mesophilic methanogens.
