Genetic organization of the predicted lactate and L-rhamnose catabolic gene clusters in Endozoicomonas sp. OPT23. (A) Lactate catabolic gene cluster coding for D-lactate dehydrogenase (dldD), three iron-sulfur-containing proteins (lutABC), and transcriptional regulator (phdR). (B) L-rhamnose (L-Rha) utilization pathway gene cluster encoding for the enzymes L-rhamnulose-1-phosphate aldolase (rhaD), L-rhamnulokinase (rhaB), L-rhamnulose isomerase (rhaA), L-rhamnulose mutarotase (rhaM), L-Rha uptake transporter genes (rhaSGHI), and transcriptional regulator (deoR). A schematic diagram illustrating the conversion of L-Rha to the final products is also shown. Straight and curved arrows indicate the enzymatic reactions and the genes involved in each step, respectively.
