Abstract:Similarities between the nitrogen-fixing systems of the archaebacteriumMethanosarcina barkeri (strain Fusaro) and a number of eubacteria were investigated. Using antibodies againstRhizobium leguminosarum nitrogenase and a probe of clonednif-HDK genes of this species, homology withM. barkeri was demonstrated on the protein level and to a greater extent on the DNA level.
