Wolfgang Eisenreich er at.: Methanopterin biosynthesis Pteridines Vol. 5, 1994, pp. 8-17 Biosynthesis of Methanopterin In Methanobacterium thermoautotrophicum Wolfgang Eisenreich and Adelbert Bacher Lehrstuhl fur Organische Chemie und Biochemie, Technische Universitat Munchen, Lichtenbergstr. 4, D-85747 Garching, Federal Republic of Germany (Received November 15, 1993) Summary The early steps in the biosynthesis of methanopterin in Methanobacterium thennoautotrophicum were analyzed by in vivo incorporation experiments of DC labeled precursors and by

Carotenoid Biosynthesis — a Target for Herbicide Activity George Britton Department of Biochemistry, The University of Liverpool, P.O. Box 147, Liverpool L69 3BX, England Z. Naturforsch. 34 c, 979 — 985 (1979) ; received May 6, 1979 Chloroplast Pigments, Photoprotection by Carotenoids, Carotenoid Biosynthesis, Phytoene, Desatura­ tion Carotenoids are chloroplast constituents. In vivo different carotenoids may be present at different sites within the chloroplast, and may have different functions. Especially important is a role in protecting the chloroplast and

On the Origin of Protein Biosynthesis B. R. Thomas Organic Chemistry 2, Lund University, Lund (Z. Naturforsch. 30 c, 32 3 —326 [1975] ; received December 10, 1974) Evolution, Genetic Code, Codon-anticodon Site, Protein Biosynthesis There is a very close steric relationship between the codon-anticodon site which accounts for the genetic code dictionary and a polynucleotide replicase site. Protein biosynthesis must therefore have arisen out of a primaeval polynucleotide replicase system. The most important step in the evolution of life has been the bringing

Chem. 2013; 394(2): 251–259 Minireview Bertolt Gust * , Kornelia Eitel and Xiaoyu Tang The biosynthesis of caprazamycins and related liponucleoside antibiotics: new insights Abstract: The first step in the membrane cycle of reac- tions during peptidoglycan biosynthesis is the transfer of phospho-MurNAc-pentapeptide from UDP-MurNAc- pentapeptide to undecaprenyl phosphate, catalyzed by the integral membrane protein MraY translocase. Differ- ent MraY inhibitors are known and can be subdivided into classes
