Electrophoretic Characterization of Ribosomal Proteins from Methanogenic Bacteria 产甲烷菌核糖体蛋白的电泳特性研究

H.</em> Ribosomes from <em>Ms. barkeri</em> were analysed in more detail. They possess an apparent sedimentation constant of 70S and dissociate at 1 mM Mg<sup>++</sup> into 30S and 50S subunits. Electropherograms of 30 S subunits purified twice on sucrose gradients exhibit at least 27 protein spots, those for 50S subunits at least 33. The individuality of these spots has not yet rigorously been determined. The electrophoretic pattern of the two strains of <em>Ms. barkeri</em> investigated differ with respect to a considerable number of proteins, which indicates a high degree of diversity even within one morphologically similar group.</p><p>The number of ribosomal proteins, as judged from the 70S electropherograms from other methanogens studied, lies in the typical “procaryotic” range, between 50 and 55. Striking, however, is the large number of acidic proteins in all strains, Their content is highest in <em>Mb. arbophilicum</em>, in which almost 2/3 of the proteins are acidic, and lowest in <em>Mc. vannielii</em>, of which about 1/3 of the total number of ribosomal proteins migrate to the anode. As ribosomes from extreme halophiles consist almost exclusively of acidic proteins, this unusual property is consistent with the comparatively high degree of 16 s RNA sequence homologies between halobacteria and one specific group (group I) of the methanogens (<em>Magrum</em> et al, 1978). Those species from group I investigated (<em>Mb. arbophilicum</em>; <em>Mb. formicicum; Mb.</em> strain <em>M.o.H</em>) also exhibit a qualitative resemblance in their ribosomal protein pattern; the patterns from <em>Mb. formicicum</em> and <em>Mb</em>. strain <em>M.o.H</em> are very similar. The practical value of ribosomal protein determination for the rapid identification or comparison of unclassified isolates is discussed.</p></div>","PeriodicalId":101294,"journal":{"name":"Zentralblatt für Bakteriologie: I.
