Phylogenetic analysis of erythritol catabolic loci within the Rhizobiales and proteobacteria.

ABSTRACT:

Background

The ability to use erythritol as a sole carbon source is not universal among the Rhizobiaceae. Based on the relatedness to the catabolic genes in Brucella it has been suggested that the eryABCD operon may have been horizontally transferred into Rhizobium. During work characterizing a locus necessary for the transport and catabolism of erythritol, adonitol and L-arabitol in Sinorhizobium meliloti, we became interested in the differences between the erythritol loci of S. meliloti and R. leguminosarum. Utilizing the Ortholog Neighborhood Viewer from the DOE Joint Genome Institute database it appeared that loci for erythritol and polyol utilization had distinct arrangements that suggested these loci may have undergone genetic rearrangements.
