Fig 2.

Comparison of the melezitose, raffinose, and stachyose gene clusters of B. breve UCC2003 with corresponding putative melezitose, raffinose, and stachyose utilization loci of other bifidobacteria. Each solid arrow represents an ORF. The length of each arrow is proportional to the length of the predicted ORF, and the gene locus name, which is indicative of its putative function, is given at the top. Orthologs are shown in the same color. The amino acid identity of each predicted protein to its equivalent protein encoded by B. breve UCC2003, expressed as a percentage, is given above each arrow.
