Novel reconstructed regulons for rhamnose metabolism in Bacillales. The genes in each regulated operon are shown by arrows; TF genes are in black, ABC transporters are in dark gray, catabolic enzymes and other genes present in B. subtilis are in light gray, and genes lacking orthologs in B. subtilis are in white. TF binding sites are shown by circles (RhaR) (A), triangles (RhgR) (B), and squares (RmgR) (C). Regulons upregulated by growth on type I rhamnogalacturonan are marked with asterisks.
