Abstract


The aim of the study was the identification of the homologues of the Mam proteins mediating the magnetite synthesis of Magnetospirillum gryphiswaldense MSR-1 in the proteome of agrobacteria and their host plants. The identification of the protein homologues was performed by pairwise alignment using the online-service BLAST. It was shown that the strains of symbiotic and pathogenic agrobacteria (AB) that are able for the root nodules formation and their typical host plants could be potential producers contain the homologues of proteins indispensable for magnetite synthesis (MamВ, MamМ, Mamand MamО) in magnetotactic bacteria (MTB). These homologues have a common ancestor, similar folding and common functions with the respective proteins of MTB. Thus, the symbiotic and pathogenic agrobacteria and host plants could be the potential producers of biogenic magnetic nanoparticles or magnetosensitive nanostructures.
