    <p>Two pairs of degenerate primers, COM1_F&COM1_R (<i>Comamonas</i>-type), and PSE1_F&PSE1_R (<i>Pseudomonas</i>-type) (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0047530#pone-0047530-t001" target="_blank">Table 1</a>) and different DNA templates: 1, 2 - <sup>13</sup>C-DNA; 3, 4 - <sup>12</sup>C-DNA; 5– blank control were used. M - DNA molecular weight Ladder.</p

    <p>The <i>nag2</i> operon was of a mosaic-type pattern. The gray scale of individual genes within the <i>nag2</i> operon indicates % similarity to <i>nag</i>-U2 (black) or <i>nag</i>-CJ2 (white). The numbers beneath the <i>nag</i>2 operon indicates the % similarity to <i>nag</i>-U2/<i>nag</i>-CJ2/neither.</p

    Bioluminescence of biosensor transducers incorporating DHN degradation genes.

    <p>ADPWH_Nag containing a <i>nag</i>2 gene cluster was rapidly activated to show bioluminescence after the addition of 50 µM DHN, confirming the function of the gene cluster. No bioluminescence was detected in the absence DHN. The negative control ADPWH_1274 did not respond to DHN. ADPWH_Nah containing a <i>nah</i> gene cluster was used as a positive control.</p
