The DNA-binding HU-type proteins from several species of Rhizobiaceae including Rhizobium meliloti, two strains of Rhizobium leguminosarum with highly different phenotypic characters and Agrobacterium tumefaciens, were characterized and their amino acid sequences were determined. HU-type proteins isolated from R. leguminosarum L18 and A. tumefaciens are identical and show slight differences with the R. meliloti HU-type protein. On the other hand the R. leguminosarum L53 HU-type protein is quite different from the proteins cited above; several amino acid substitutions encountered in this protein result in significant changes in the folding of the polypeptide chain. The biochemical characteristics of these proteins are in good agreement with the respective position of these bacteria in the phylogeny determined by numerical taxonomy.
