L-rhamnose (L-Rha) is a deoxy-hexose sugar commonly found in nature. L-Rha catabolic
pathways were previously characterized in various bacteria including Escherichia coli.
Nevertheless, homology searches failed to recognize all the genes for the complete L-Rha
utilization pathways in diverse microbial species involved in biomass decomposition.
Moreover, the regulatory mechanisms of L-Rha catabolism have remained unclear in most
species. A comparative genomics approach was used to reconstruct the L-Rha catabolic …
