[The cnr-like operon in strain Comamonas sp. encoding resistance to cobalt and nickel].
Plasmid pBS501 was detected in the strain Comamonas sp. BS501. This plasmid specifies high level of induced resistance (5 mM) to cobalt/nickel both in the host strain and in related strains C. testosteroni B-1241 and C. acidovorans B-1251. Hybridization analysis revealed a homology of pBS501 restriction fragments with the only well-characterized operon cnrXYHCBAT that resides in plasmid pMOL28 from Cupriavidus metallidurans CH34. Essential differences in the structural organization of the cobalt/nickel resistance determinant were found between plasmid pBS501 and the cnr-operon.
